You can prevent lung cancer


Breathing properly is fundamental to good health, and you shouldn't take your respiratory system for granted, especially if you live in a big city.  In addition to prudent supplementation and a diet rich in beta-carotene and other antioxidants, simple lifestyle steps can help promote healthy lungs for a lifetime.

  1. Don't smoke. Tobacco addiction is the single greatest cause of preventable illness, greatly increasing the risks of developing lung cancer and respiratory diseases.
  2. Get regular exercise. It helps promote healthy lung function and optimal oxygen delivery throughout the body.
  3. Practice deep breathing exercises to increase lung capacity, improve respiratory efficiency, and promote general relaxation.
  4. Maintain a normal weight. Excess pounds tax both the heart and lungs. If you're overweight, you're more likely to experience shortness of breath.
  5. Avoid exposure to environmental air pollutants. High ozone levels, smog, car exhaust, asbestos and metal dusts are unhealthy for lungs and can lead to lung disease. Use a HEPA (high-efficiency particulate air) filter to reduce exposure to smoke and smog, and wear a protective mask when you are in close proximity to lung irritants such as drywall dust or fiberglass insulation fibers.
  6. Limit exposure to toxic household cleaners. Chlorine bleach, petroleum distillates, ammonia, formaldehyde and nitrobenzene can harm the lungs. Use safer alternatives for cleaning such as baking soda, lemon juice, and vinegar.

Prevent Prostate Cancer!!!

The Prostate Gland
The prostate is a walnut-sized gland that forms part of the male reproductive system. The gland is made of two lobes, or regions, enclosed by an outer layer of tissue. As the diagrams show, the prostate is located in front of the rectum and just below the bladder, where urine is stored. The prostate also surrounds the urethra, the canal through which urine passes out of the body.
Scientists do not know all the prostate's functions. One of its main roles, though, is to squeeze fluid into the urethra as sperm move through during sexual climax. This fluid, which helps make up semen, energizes the sperm and makes the vaginal canal less acidic.
Benign Prostatic Hyperplasia
It is common for the prostate gland to become enlarged as a man ages. Doctors call this condition benign prostatic hyperplasia (BPH), or benign prostatic hypertrophy.
As a man matures, the prostate goes through two main periods of growth. The first occurs early in puberty, when the prostate doubles in size. At around age 25, the gland begins to grow again. This second growth phase often results, years later, in BPH.
Though the prostate continues to grow during most of a man's life, the enlargement doesn't usually cause problems until late in life. BPH rarely causes symptoms before age 40, but more than half of men in their sixties and as many as 90 percent in their seventies and eighties have some symptoms of BPH.
As the prostate enlarges, the layer of tissue surrounding it stops it from expanding, causing the gland to press against the urethra like a clamp on a garden hose. The bladder wall becomes thicker and irritable. The bladder begins to contract even when it contains small amounts of urine, causing more frequent urination. Eventually, the bladder weakens and loses the ability to empty itself, so some of the urine remains in the bladder. The narrowing of the urethra and partial emptying of the bladder cause many of the problems associated with BPH.
Many people feel uncomfortable talking about the prostate, since the gland plays a role in both sex and urination. Still, prostate enlargement is as common a part of aging as gray hair. As life expectancy rises, so does the occurrence of BPH. In the United States in 2000, there were 4.5 million visits to physicians for BPH.
Why BPH Occurs
The cause of BPH is not well understood. No definite information on risk factors exists. For centuries, it has been known that BPH occurs mainly in older men and that it doesn't develop in men whose testes were removed before puberty. For this reason, some researchers believe that factors related to aging and the testes may spur the development of BPH.
Throughout their lives, men produce both testosterone, an important male hormone, and small amounts of estrogen, a female hormone. As men age, the amount of active testosterone in the blood decreases, leaving a higher proportion of estrogen. Studies done on animals have suggested that BPH may occur because the higher amount of estrogen within the gland increases the activity of substances that promote cell growth.
Another theory focuses on dihydrotestosterone (DHT), a substance derived from testosterone in the prostate, which may help control its growth. Most animals lose their ability to produce DHT as they age. However, some research has indicated that even with a drop in the blood's testosterone level, older men continue to produce and accumulate high levels of DHT in the prostate. This accumulation of DHT may encourage the growth of cells. Scientists have also noted that men who do not produce DHT do not develop BPH.
Some researchers suggest that BPH may develop as a result of "instructions" given to cells early in life. According to this theory, BPH occurs because cells in one section of the gland follow these instructions and "reawaken" later in life. These "reawakened" cells then deliver signals to other cells in the gland, instructing them to grow or making them more sensitive to hormones that influence growth.
Symptoms
Many symptoms of BPH stem from obstruction of the urethra and gradual loss of bladder function, which results in incomplete emptying of the bladder. The symptoms of BPH vary, but the most common ones involve changes or problems with urination, such as
a hesitant, interrupted, weak stream
urgency and leaking or dribbling
more frequent urination, especially at night
The size of the prostate does not always determine how severe the obstruction or the symptoms will be. Some men with greatly enlarged glands have little obstruction and few symptoms while others, whose glands are less enlarged, have more blockage and greater problems.
Sometimes a man may not know he has any obstruction until he suddenly finds himself unable to urinate at all. This condition, called acute urinary retention, may be triggered by taking over-the-counter cold or allergy medicines. Such medicines contain a decongestant drug, known as a sympathomimetic. A potential side effect of this drug may prevent the bladder opening from relaxing and allowing urine to empty. When partial obstruction is present, urinary retention also can be brought on by alcohol, cold temperatures, or a long period of immobility.
It is important to tell your doctor about urinary problems such as those described above. In eight out of 10 cases, these symptoms suggest BPH, but they also can signal other, more serious conditions that require prompt treatment. These conditions, including prostate cancer, can be ruled out only by a doctor's examination.
Severe BPH can cause serious problems over time. Urine retention and strain on the bladder can lead to urinary tract infections, bladder or kidney damage, bladder stones, and incontinence-the inability to control urination. If the bladder is permanently damaged, treatment for BPH may be ineffective. When BPH is found in its earlier stages, there is a lower risk of developing such complications.
Diagnosis
You may first notice symptoms of BPH yourself, or your doctor may find that your prostate is enlarged during a routine checkup. When BPH is suspected, you may be referred to a urologist, a doctor who specializes in problems of the urinary tract and the male reproductive system. Several tests help the doctor identify the problem and decide whether surgery is needed. The tests vary from patient to patient, but the following are the most common.
Digital Rectal Examination (DRE)
This examination is usually the first test done. The doctor inserts a gloved finger into the rectum and feels the part of the prostate next to the rectum. This examination gives the doctor a general idea of the size and condition of the gland.
Prostate-Specific Antigen (PSA) Blood Test
To rule out cancer as a cause of urinary symptoms, your doctor may recommend a PSA blood test. PSA, a protein produced by prostate cells, is frequently present at elevated levels in the blood of men who have prostate cancer. The U.S. Food and Drug Administration (FDA) has approved a PSA test for use in conjunction with a digital rectal examination to help detect prostate cancer in men who are age 50 or older and for monitoring men with prostate cancer after treatment. However, much remains unknown about the interpretation of PSA levels, the test's ability to discriminate cancer from benign prostate conditions, and the best course of action following a finding of elevated PSA.
A fact sheet titled "The Prostate-Specific Antigen (PSA) Test: Questions and Answers" can be found on the National Cancer Institute website at www.cancer.gov/cancertopics/factsheet/Detection/PSA.
Rectal Ultrasound and Prostate Biopsy
If there is a suspicion of prostate cancer, your doctor may recommend a test with rectal ultrasound. In this procedure, a probe inserted in the rectum directs sound waves at the prostate. The echo patterns of the sound waves form an image of the prostate gland on a display screen. To determine whether an abnormal-looking area is indeed a tumor, the doctor can use the probe and the ultrasound images to guide a biopsy needle to the suspected tumor. The needle collects a few pieces of prostate tissue for examination with a microscope.
Urine Flow Study
Your doctor may ask you to urinate into a special device that measures how quickly the urine is flowing. A reduced flow often suggests BPH.
Cystoscopy
In this examination, the doctor inserts a small tube through the opening of the urethra in the penis. This procedure is done after a solution numbs the inside of the penis so all sensation is lost. The tube, called a cystoscope, contains a lens and a light system that help the doctor see the inside of the urethra and the bladder. This test allows the doctor to determine the size of the gland and identify the location and degree of the obstruction.
Treatment
Men who have BPH with symptoms usually need some kind of treatment at some time. However, a number of researchers have questioned the need for early treatment when the gland is just mildly enlarged. The results of their studies indicate that early treatment may not be needed because the symptoms of BPH clear up without treatment in as many as one-third of all mild cases. Instead of immediate treatment, they suggest regular checkups to watch for early problems. If the condition begins to pose a danger to the patient's health or causes a major inconvenience to him, treatment is usually recommended.
Since BPH can cause urinary tract infections, a doctor will usually clear up any infection with antibiotics before treating the BPH itself. Although the need for treatment is not usually urgent, doctors generally advise going ahead with treatment once the problems become bothersome or present a health risk.
The following section describes the types of treatment that are most commonly used for BPH.
Drug Treatment
Over the years, researchers have tried to find a way to shrink or at least stop the growth of the prostate without using surgery. The FDA has approved six drugs to relieve common symptoms associated with an enlarged prostate.
Finasteride (Proscar), FDA-approved in 1992, and dutasteride (Avodart), FDA-approved in 2001, inhibit production of the hormone DHT, which is involved with prostate enlargement. The use of either of these drugs can either prevent progression of growth of the prostate or actually shrink the prostate in some men.
The FDA also approved the drugs terazosin (Hytrin) in 1993, doxazosin (Cardura) in 1995, tamsulosin (Flomax) in 1997, and alfuzosin (Uroxatral) in 2003 for the treatment of BPH. All four drugs act by relaxing the smooth muscle of the prostate and bladder neck to improve urine flow and to reduce bladder outlet obstruction. The four drugs belong to the class known as alpha blockers. Terazosin and doxazosin were developed first to treat high blood pressure. Tamsulosin and alfuzosin were developed specifically to treat BPH.
The Medical Therapy of Prostatic Symptoms (MTOPS) Trial, supported by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), recently found that using finasteride and doxazosin together is more effective than using either drug alone to relieve symptoms and prevent BPH progression. The two-drug regimen reduced the risk of BPH progression by 67 percent, compared with 39 percent for doxazosin alone and 34 percent for finasteride alone.

Minimally Invasive Therapy
Because drug treatment is not effective in all cases, researchers in recent years have developed a number of procedures that relieve BPH symptoms but are less invasive than conventional surgery.
Transurethral microwave procedures,  In 1996, the FDA approved a device that uses microwaves to heat and destroy excess prostate tissue. In the procedure called transurethral microwave thermotherapy (TUMT), the device sends computer-regulated microwaves through a catheter to heat selected portions of the prostate to at least 111 degrees Fahrenheit. A cooling system protects the urinary tract during the procedure.
The procedure takes about 1 hour and can be performed on an outpatient basis without general anesthesia. TUMT has not been reported to lead to erectile dysfunction or incontinence.
Although microwave therapy does not cure BPH, it reduces urinary frequency, urgency, straining, and intermittent flow. It does not correct the problem of incomplete emptying of the bladder. Ongoing research will determine any long-term effects of microwave therapy and who might benefit most from this therapy.
Transurethral needle ablation,  Also in 1996, the FDA approved the minimally invasive transurethral needle ablation (TUNA) system for the treatment of BPH.
The TUNA system delivers low-level radiofrequency energy through twin needles to burn away a well-defined region of the enlarged prostate. Shields protect the urethra from heat damage. The TUNA system improves urine flow and relieves symptoms with fewer side effects when compared with transurethral resection of the prostate (TURP). No incontinence or impotence has been observed.
Water-induced thermotherapy, This therapy uses heated water to destroy excess tissue in the prostate. A catheter containing multiple shafts is positioned in the urethra so that a treatment balloon rests in the middle of the prostate. A computer controls the temperature of the water, which flows into the balloon and heats the surrounding prostate tissue. The system focuses the heat in a precise region of the prostate. Surrounding tissues in the urethra and bladder are protected. Destroyed tissue either escapes with urine through the urethra or is reabsorbed by the body.
High-intensity focused ultrasound. The use of ultrasound waves to destroy prostate tissue is still undergoing clinical trials in the United States. The FDA has not yet approved high-intensity focused ultrasound.
Surgical Treatment
Most doctors recommend removal of the enlarged part of the prostate as the best long-term solution for patients with BPH. With surgery for BPH, only the enlarged tissue that is pressing against the urethra is removed; the rest of the inside tissue and the outside capsule are left intact. Surgery usually relieves the obstruction and incomplete emptying caused by BPH. The following section describes the types of surgery that are used.
Transurethral surgery,  In this type of surgery, no external incision is needed. After giving anesthesia, the surgeon reaches the prostate by inserting an instrument through the urethra.
A procedure called transurethral resection of the prostate (TURP) is used for 90 percent of all prostate surgeries done for BPH. With TURP, an instrument called a resectoscope is inserted through the penis. The resectoscope, which is about 12 inches long and 1/2 inch in diameter, contains a light, valves for controlling irrigating fluid, and an electrical loop that cuts tissue and seals blood vessels.
During the 90-minute operation, the surgeon uses the resectoscope's wire loop to remove the obstructing tissue one piece at a time. The pieces of tissue are carried by the fluid into the bladder and then flushed out at the end of the operation.
Most doctors suggest using TURP whenever possible. Transurethral procedures are less traumatic than open forms of surgery and require a shorter recovery period. One possible side effect of TURP is retrograde, or backward, ejaculation. In this condition, semen flows backward into the bladder during climax instead of out the urethra.
Another surgical procedure is called transurethral incision of the prostate (TUIP). Instead of removing tissue, as with TURP, this procedure widens the urethra by making a few small cuts in the bladder neck, where the urethra joins the bladder, and in the prostate gland itself. Although some people believe that TUIP gives the same relief as TURP with less risk of side effects such as retrograde ejaculation, its advantages and long-term side effects have not been clearly established.
Open surgery, In the few cases when a transurethral procedure cannot be used, open surgery, which requires an external incision, may be used. Open surgery is often done when the gland is greatly enlarged, when there are complicating factors, or when the bladder has been damaged and needs to be repaired. The location of the enlargement within the gland and the patient's general health help the surgeon decide which of the three open procedures to use.
With all the open procedures, anesthesia is given and an incision is made. Once the surgeon reaches the prostate capsule, he or she scoops out the enlarged tissue from inside the gland.
Laser surgery, In March 1996, the FDA approved a surgical procedure that employs side-firing laser fibers and Nd: YAG lasers to vaporize obstructing prostate tissue. The doctor passes the laser fiber through the urethra into the prostate using a cystoscope and then delivers several bursts of energy lasting 30 to 60 seconds. The laser energy destroys prostate tissue and causes shrinkage. As with TURP, laser surgery requires anesthesia and a hospital stay. One advantage of laser surgery over TURP is that laser surgery causes little blood loss. Laser surgery also allows for a quicker recovery time. But laser surgery may not be effective on larger prostates. The long-term effectiveness of laser surgery is not known.
Newer procedures that use laser technology can be performed on an outpatient basis.
Photoselective vaporization of the prostate (PVP), PVP uses a high-energy laser to destroy prostate tissue and seal the treated area.
Interstitial laser coagulation, Unlike other laser procedures, interstitial laser coagulation places the tip of the fiberoptic probe directly into the prostate tissue to destroy it.

Your Recovery After Surgery in the Hospital

The amount of time you will stay in the hospital depends on the type of surgery you had and how quickly you recover.
At the end of surgery, a special catheter is inserted through the opening of the penis to drain urine from the bladder into a collection bag. Called a Foley catheter, this device has a water-filled balloon on the end that is put in the bladder, which keeps it in place.
This catheter is usually left in place for several days. Sometimes, the catheter causes recurring painful bladder spasms the day after surgery. These spasms may be difficult to control, but they will eventually disappear.
You may also be given antibiotics while you are in the hospital. Many doctors start giving this medicine before or soon after surgery to prevent infection. However, some recent studies suggest that antibiotics may not be needed in every case, and your doctor may prefer to wait until an infection is present to give them.
After surgery, you will probably notice some blood or clots in your urine as the wound starts to heal. If your bladder is being irrigated (flushed with water), you may notice that your urine becomes red once the irrigation is stopped. Some bleeding is normal, and it should clear up by the time you leave the hospital. During your recovery, it is important to drink a lot of water (up to 8 cups a day) to help flush out the bladder and speed healing.

Do's and Don'ts
Take it easy the first few weeks after you get home. You may not have any pain, but you still have an incision that is healing-even with transurethral surgery, where the incision can't be seen. Since many people try to do too much at the beginning and then have a setback, it is a good idea to talk with your doctor before resuming your normal routine. During this initial period of recovery at home, avoid any straining or sudden movements that could tear the incision.
Here are some guidelines:
·         Continue drinking a lot of water to flush the bladder.
·         Avoid straining when having a bowel movement.
·         Eat a balanced diet to prevent constipation. If constipation occurs, ask your doctor if you can take a laxative.
·         Don't do any heavy lifting.
·         Don't drive or operate machinery.

Getting Back to Normal After Surgery

Even though you should feel much better by the time you leave the hospital, it will probably take a couple of months for you to heal completely. During the recovery period, the following are some common problems that can occur.
Problems Urinating
You may notice that your urinary stream is stronger right after surgery, but it may take awhile before you can urinate completely normally again. After the catheter is removed, urine will pass over the surgical wound on the prostate, and you may initially have some discomfort or feel a sense of urgency when you urinate. This problem will gradually lessen, and after a couple of months you should be able to urinate less frequently and more easily.
Incontinence
As the bladder returns to normal, you may have some temporary problems controlling urination, but long-term incontinence rarely occurs. Doctors find that the longer problems existed before surgery, the longer it takes for the bladder to regain its full function after the operation.
Bleeding
In the first few weeks after transurethral surgery, the scab inside the bladder may loosen, and blood may suddenly appear in the urine. Although this can be alarming, the bleeding usually stops with a short period of resting in bed and drinking fluids. However, if your urine is so red that it is difficult to see through or if it contains clots or if you feel any discomfort, be sure to contact your doctor.

Sexual Function After Surgery

Many men worry about whether surgery for BPH will affect their ability to enjoy sex. Some sources state that sexual function is rarely affected, while others claim that it can cause problems in up to 30 percent of cases. However, most doctors say that even though it takes awhile for sexual function to return fully, with time, most men are able to enjoy sex again.
Complete recovery of sexual function may take up to 1 year, lagging behind a person's general recovery. The exact length of time depends on how long after symptoms appeared that BPH surgery was done and on the type of surgery. Following is a summary of how surgery is likely to affect the following aspects of sexual function.
Erections
Most doctors agree that if you were able to maintain an erection shortly before surgery, you will probably be able to have erections afterward. Surgery rarely causes a loss of erectile function. However, surgery cannot usually restore function that was lost before the operation.
Ejaculation
Although most men are able to continue having erections after surgery, a prostate procedure frequently makes them sterile (unable to father children) by causing a condition called retrograde ejaculation or dry climax.
During sexual activity, sperm from the testes enters the urethra near the opening of the bladder. Normally, a muscle blocks off the entrance to the bladder, and the semen is expelled through the penis. However, the coring action of prostate surgery cuts this muscle as it widens the neck of the bladder. Following surgery, the semen takes the path of least resistance and enters the wider opening to the bladder rather than being expelled through the penis. Later it is harmlessly flushed out with urine. In some cases, this condition can be treated with a drug called pseudoephedrine, found in many cold medicines, or imipramine. These drugs improve muscle tone at the bladder neck and keep semen from entering the bladder.
Orgasm
Most men find little or no difference in the sensation of orgasm, or sexual climax, before and after surgery. Although it may take some time to get used to retrograde ejaculation, you should eventually find sex as pleasurable after surgery as before.
Many people have found that concerns about sexual function can interfere with sex as much as the operation itself. Understanding the surgical procedure and talking over any worries with the doctor before surgery often help men regain sexual function earlier. Many men also find it helpful to talk with a counselor during the adjustment period after surgery.

Is Further Treatment Needed?

In the years after your surgery, it is important to continue having a rectal examination once a year and to have any symptoms checked by your doctor.
Since surgery for BPH leaves behind a good part of the gland, it is still possible for prostate problems, including BPH, to develop again. However, surgery usually offers relief from BPH for at least 15 years. Only 10 percent of the men who have surgery for BPH eventually need a second operation for enlargement. Usually these are men who had the first surgery at an early age.
Sometimes, scar tissue resulting from surgery requires treatment in the year after surgery. Rarely, the opening of the bladder becomes scarred and shrinks, causing obstruction. This problem may require a surgical procedure similar to transurethral incision (see section on Surgical Treatment). More often, scar tissue may form in the urethra and cause narrowing. The doctor can solve this problem during an office visit by stretching the urethra.

Prostatic Stents
A stent is a small device that is inserted through the urethra to the narrowed area and allowed to expand, like a spring. The stent pushes back the prostatic tissue, widening the urethra. It is designed to relieve urinary obstruction in men and improve the ability to urinate. The device is approved for use in men for whom other standard surgical procedures to correct urinary obstruction have failed.

BPH and Prostate Cancer: No Apparent Relation
Although some of the signs of BPH and prostate cancer are the same, having BPH does not seem to increase the chances of getting prostate cancer. Nevertheless, a man who has BPH may have undetected prostate cancer at the same time or may develop prostate cancer in the future. For this reason, the National Cancer Institute and the American Cancer Society recommend that all men over 40 have a rectal examination once a year to screen for prostate cancer.
After BPH surgery, the tissue removed is routinely checked for hidden cancer cells. In about one out of 10 cases, some cancer tissue is found, but often it is limited to a few cells of a nonaggressive type of cancer, and no treatment is needed.

Hope through Research
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) was established by Congress in 1950 as one of the National Institutes of Health (NIH), whose mission is to improve human health through biomedical research. NIH is the research branch of the U.S. Department of Health and Human Services.
The NIDDK conducts and supports a variety of research in diseases of the kidney and urinary tract. Much of the research targets disorders of the lower urinary tract, including BPH, urinary tract infection, interstitial cystitis, urinary obstruction, prostatitis, and urinary stones. The knowledge gained from these studies is advancing scientific understanding of why BPH develops and may lead to improved methods of diagnosing and treating prostate enlargement. One such study was the MTOPS Trial , which ended in 2003. The results are summarized above under the Drug Treatment section.

PREVENTION
There's no proven prostate cancer prevention strategy. But you may reduce your risk of prostate cancer by making healthy choices, such as exercising and eating a healthy diet.
If you're concerned about your risk of prostate cancer, you may be interested in prostate cancer prevention. Prostate cancer is the most common cancer diagnosed in men. You may have friends or family members who have been diagnosed with prostate cancer, and this may make you wonder about what you can do for prostate cancer prevention.
There's no sure way to prevent prostate cancer. Study results often conflict with each other, and no clear ways to prevent prostate cancer have emerged. In general, doctors recommend that men with an average risk of prostate cancer make choices that benefit their overall health if they're interested in prostate cancer prevention.
Choose a healthy diet
There is some evidence that choosing a healthy diet that's low in fat and full of fruits and vegetables may reduce your risk of prostate cancer, though study results haven't always agree. If you want to reduce your risk of prostate cancer, consider trying to:

Choose a low-fat diet.
Foods that contain fats include meats, nuts, oils and dairy products, such as milk and cheese. In studies, men who ate the highest amount of fat each day had an increased risk of prostate cancer. While this association doesn't prove that excess fat causes prostate cancer, reducing the amount of fat you eat each day has other proven benefits, such as helping you control your weight and helping your heart. To reduce the amount of fat you eat each day, limit fatty foods or choose low-fat varieties. For instance, reduce the amount of fat you add to foods when cooking, select leaner cuts of meat and choose low-fat or reduced-fat dairy products.
Eat more fat from plants than from animals.
In studies that looked at fat and prostate cancer risk, fats from animals were most likely to be associated with an increased risk of prostate cancer. Animal products that contain fats include meat, lard and butter. When possible, use plant-based fats in place of animal fats. For instance, cook with olive oil rather than butter. Sprinkle nuts or seeds on your salad rather than cheese.
Increase the amount of fruits and vegetables you eat each day.
Fruits and vegetables are full of vitamins and nutrients that are thought to reduce the risk of prostate cancer, though research hasn't proved that any particular nutrient is guaranteed to reduce your risk. Eating more fruits and vegetables also tends to make you have less room for other foods, such as high-fat foods. Increase the amount of fruits and vegetables you eat each day by adding an additional serving of a fruit or vegetable to each meal. Eat fruits and vegetables for snacks.
Eat fish.
Fatty fish — such as salmon, sardines, tuna and trout — contain a fatty acid called omega-3 that has been linked to a reduced risk of prostate cancer. If you don't currently eat fish, try adding it to your diet.
Reduce the amount of dairy products you eat each day.
In studies, men who ate the most dairy products — such as milk, cheese and yogurt — each day had the highest risk of prostate cancer. But study results have been mixed, and the risk associated with dairy products is thought to be small.
Drink green tea.
Studies of men who drink green tea or take green tea extract as a supplement have found a reduced risk of prostate cancer. If you like to drink tea, consider choosing green tea.
Try adding soy to your diet.
Diets that include tofu — a product made from soy beans — have been linked to a reduced risk of prostate cancer. It's thought that the benefit of soy comes from a specific nutrient called isoflavones. Other sources of isoflavones include kidney beans, chickpeas, lentils and peanuts.
Drink alcohol in moderation.
If you choose to drink alcohol, limit yourself to no more than a drink or two each day. There's no clear evidence that drinking alcohol can affect your risk of prostate cancer, but one study found men who drank several drinks each day over many years had an increased risk.
Maintain a healthy weight
Men with a body mass index (BMI) of 30 or higher are considered obese. Being obese increases your risk of prostate cancer. If you are overweight or obese, work to lose weight. You can do this by reducing the number of calories you eat each day and increasing the amount of exercise you do.If you have a healthy weight, work to maintain it by exercising most days of the week and choosing a healthy diet that's rich in fruits, vegetables and whole grains.
Exercise most days of the week
Studies of exercise and prostate cancer risk have mostly shown that men who exercise may have a reduced risk of prostate cancer. But not all studies have agreed. Exercise has many other health benefits and may reduce your risk of heart disease and other cancers. Exercise can help you maintain your weight, or it can help you lose weight.
If you don't already exercise, make an appointment with your doctor to ensure it's OK for you to get started. When you begin exercising, go slowly. Add physical activity to your day by parking your car farther away from where you're going, and try taking the stairs instead of the elevator. Aim for 30 minutes of exercise most days of the week.
Talk to your doctor about your risk
Some men have an increased risk of prostate cancer. For those with a very high risk of prostate cancer, there may be other options for risk reduction, such as medications. If you think you have a high risk of prostate cancer, discuss it with your doctor.

3 ways to get rid of acne


Exercise 

"We tend to focus on the cardiovascular benefits of physical activity, and those are important. But anything that promotes healthy circulation also helps keep your skinhealthy and vibrant," says dermatologist Ellen Marmur, MD, author of Simple Skin Beauty: Every Woman's Guide to a Lifetime of Healthy, Gorgeous Skin and associate professor of dermatology at Mount Sinai School of Medicine. 
If you have dermatological conditions such as acnerosacea, or psoriasis, you may need to take special care to keep your skin protected while exercising. But don't let skin problems prevent you from being active. Here's why.
By increasing blood flow, exercise helps nourish skin cells and keep them vital. "Blood carries oxygen and nutrients to working cells throughout the body, including the skin," says Marmur. In addition to providing oxygen, blood flow also helps carry away waste products, including free radicals, from working cells. Contrary to some claims, exercise doesn't detoxify the skin. The job of neutralizing toxins belongs mostly to the liver. "But by increasing blood flow, a bout of exercise helps flush cellular debris out of the system," Marmur tells WebMD. "You can think of it as cleansing your skin from the inside."
Exercise has also been shown to ease stress. "And by decreasing stress, some conditions that can be exacerbated by stress can show some improvement," says Brian B. Adams, MD, associate professor and director of the Sports Dermatology Clinic at the University of Cincinnati. Conditions that can improve when stress is reduced include acne and eczema. Although researchers are still investigating the link between stress and skin, studies show that the sebaceous glands, which produce oil in the skin, are influenced by stress hormones.
Regular exercise helps tone muscles, of course. That doesn't have a direct affect on skin, dermatologists say. But firmer muscles definitely help you look better overall.

Have a healthy Diet
A study completed by the Australia's RMIT University and Royal Melbourne Hospital Department of Dermatology have discovered what is being hailed as a "solid link" between diet and acne development.
Associate Professor Neil Mann, from RMIT University's School of Applied Sciences, led the research team which spent more than two years studying metabolic changes in glucoseand insulin levels due to diet and the resulting changes on the skin.

Researchers believe carbohydrates with a highglycemic index, which cause glucose and insulin levels to spike, may influence the development and severity of acne. Conversely, a diet high in protein and carbohydrates with a low glycemic index seemed to improve acne breakouts.
Professor Mann, along with Robyn Smith, PhD and Royal Melbourne Hospital, divided forty-three males, between the ages of 15 and 25, into two groups. One group was given foods with a low glycemic index, such as whole grain breads and pasta, legumes, as well as high protein foods. The second group was fed a more "typical" teenage diet consisting of white bread, potatoes, and sugary drinks and snacks.
The results, researchers say, were astounding. After 12 weeks, the boys in the high protein-low glycemic index group showed a fifty percent reduction of acne. The results seem to suggest a link between diet and acne development.
The results of the study were presented at the 15th Congress of the European Academy of Dermatology and Venerology, and have been published in the July 2007 issue of the American Journal of Clinical Nutrition, and the August 2007 issue of the Journal of the American Academy of Dermatology.
Dr. Mann, along with the Australian College of Dermatologists, has published a booklet, "The Teenage Anti-acne Diet," based on his research.
What This Means to You
Dr. Mann's study is intriguing, as it challenges the long-held beliefs regarding diet and acne. Interesting as the results are, they are preliminary and more research needs to be done.
So, is diet alone going to clear your acne? Probably not. However, a healthy diet will certainly improve your overall health. Instead of highly processed foods, try incorporating more whole grains (such as whole wheat bread, wheat pastas, brown rice, oatmeal, etc.) into your diet, as well as plenty of fresh vegetables, fruit, and lean protein. Limit the amount of soda, sugary snacks, and other "junk foods" whenever possible. You have nothing to lose, and a healthy body to gain. And possibly clearer skin, too.


Take Vitamins and supplements
Healthy and radiant skin requires proper nutrition. However, according to a 2007 report by the Center for Disease Control and Prevention, 39.5 percent of Americans eat less than the recommended three to five servings of fruits and vegetables each day. Deficiencies in vitamins and minerals can affect the body's ability to function optimally. Vitamins and minerals can be taken to supplement our diets when our nutritional needs are lacking through food consumption alone.
However, multivitamins should not be taken as a substitute for eating healthy foods. Taking too much of any vitamin or mineral can be toxic and extremely dangerous. Please consult with a doctor or other trained healthcare professional before taking any dietary supplements.
·         Vitamin A - Retinoids, derivatives of vitamin A, are used to treat acne and other skin disorders. Retinoids are prescribed by dermatologists both topically and orally. A common type of retinoid used in the oral treatment of acne isisotretinoin.
·         Omega-3 Fatty Acids - Omega-3 fatty acids from fish oil, chromium, zinc, and selenium are nutrients that may have both anti-acne and mood regulating properties according to an acne study conducted at the Lasky Skin Clinic in 2008.
·         Zinc - The National Library of Science recognizes that zinc may be effective in the treatment of acne based on available science evidence. The Department of Dermatology at SUNY Downstate Medical Center in New York also recognizes zinc, along with vitamin A, and tea tree oil (also ayurvedic therapies) as over-the-counter remedies available for treating acne. However, its position on these remedies is that additional and better studies are needed to clarify the benefits.
Essential Vitamins for Skin Care in General
·         Vitamin A - According to Dr. Eugene S. Bereston "the therapeutic use of Vitamin A began almost with the discovery of the vitamin." Bereston also noted that the first property of vitamin A is its ability to stimulate growth. The American Academy of Dermatology reports that vitamin A is vital to the health of both your skin and your eyes. The academy recommends a daily dose of vitamin A. Examples of vitamin A enriched foods include citrus fruits, carrots, tomatoes, yellow squash, and pumpkin. Vitamin A can also be applied to the skin topically with creams to promote cell growth.
·         Vitamin B - The Office of Dietary Supplements at the National Institute of Health states that inflammation of the skin is one sign of B6 deficiency. Clinical signs of vitamin B6 deficiency are rarely seen in the United States. Alcoholics and aging adults are at the highest risk for B6 deficiencies due to poor dietary habits.
·         Vitamins C and E - The American Academy of Dermatology recommends daily oral dosages of vitamins C and E to protect the body and for its antioxidant properties that are important for healthy skin.
·         Zinc - A study conducted at Duke University provides evidence that Zinc is an important antioxidant supporting healthy skin. Among the findings: "Zinc protects against UV radiation, enhances wound healing, contributes to immune and neuropsychiatric functions, and decreases the relative risk of cancer and cardiovascular disease." So, in addition to the antioxidant benefits zinc offers to our skin, zinc is also important for the proper functioning of the immune system.
Proflavanol
Grape seed extract and vitamin C. The proanthocyanidins (a type of bioflavonoid) in grape seed extract appear to be some of the most powerful free-radical scavengers yet discovered. These proanthocyanidins are available in only extremely small amounts from foods. Proflavanol supplements can be a key weapon in your antioxidant arsenal. Together with vitamin C, these exclusive formulations provide you with potent free-radical scavengers for superior antioxidant protection.
