Slim Down and Pump Up for Prostate Cancer Protection
Men who have more lean body mass are less likely to get prostate cancer, according to a study in the Journal of Urology (2005;174:2169–73). Previous studies on the relationship between body size and prostate cancer have yielded conflicting results. The new study compared men with prostate cancer and their cancer-free male siblings to better understand the influence of weight, height, body mass, and body fat on prostate-cancer risk. They also looked at what influence, if any, body composition had on the aggressiveness of the cancer. Most of the men were in their early 60s.
The case-control study included 413 families: 439 men with prostate cancer (cases) and 479 cancer-free siblings (controls). The aggressiveness of prostate cancer in cases was graded on a scale of one to five based on microscopic examination of prostate tissue samples, or biopsies. The degree of cancerous infiltration throughout the gland, known as the Gleason score, can give a fairly accurate picture of the stage of cancer development when considered together with levels of prostate specific antigen (PSA) in the blood. (Outside of a study setting, a urologist would also perform a rectal examination of the prostate gland to assess its size, shape, and texture.)
Lean body mass, the total body weight not including fat, is typically higher in people who engage in regular aerobic and strength-building exercise, though it is also influenced by genetic predisposition. The researchers found that men with higher lean body mass had a lower incidence of prostate cancer than did men with low lean body mass. Researchers also found that prostate cancer was less aggressive in men with high lean body mass. Simple measurements of weight relative to height (calculated as the body mass index) did not correlate with cancer incidence or aggressiveness in this study, suggesting that something about lean body mass itself was protective.
The protective effects of lean body mass against prostate cancer may be due to comparatively higher levels of androgens, like testosterone, when lean body mass is higher. Low testosterone in aging men can promote conditions in the prostate that contribute to cancer development, and other studies have correlated low testosterone levels with more aggressive cancer. Comparing siblings makes the data from this study more useful than many others, as it significantly reduced the possibility that the findings could be confounded by genetic and early-life environmental factors. One limitation of the study was that it derived its results from a primarily white population, and therefore may not apply to other ethnic groups.
While these findings are preliminary, they suggest that doing exercises that build muscles might help prevent prostate cancer.

Green Tea and Prostate Health
New research suggests that green tea may help prevent the spread of prostate cancer. Specifically phytochemicals in green tea, called polyphenols attack growth factors and proteins, interrupting growth processes of tumors, thus preventing them from spreading to other organs. Since earlier studies suggests that the same natural plant substances might also help prevent the start of prostate cancer, researchers indicate that more studies are needed on green tea’s affect on fighting this common cancer. The best way to reduce your risk of prostate cancer still lies in eating a mostly vegetarian diet.Studies on diet and cancer also show that green tea when tested with mice with an aggressive form of cancer can decrease the spread or metastasis of prostate cancer to liver, bone, and other parts of the body. Additional study of green tea may help develop a treatment to prevent the dormant, non threatening type of prostate cancer many men have in their 70’s & 80’s from becoming aggressive and fatal. Around six cups of green tea per day would contain the equivalent amount of polyphenols for individuals to help block the spread of cancer. Other data shows that the phytochemicals in green tea could inhibit the early phases of prostate cancer development.
The phytochemicals seem to increase the number of enzymes that help convert carcinogens to dormant, harmless forms. Many questions remain about the amount and frequency of green tea necessary to affect the formation of prostate cancer. Black tea has shown similar benefits to green tea, although they appear to have lower levels of the beneficial substances than green tea. Whatever the benefits of green tea, it would be a mistake to rely on tea alone for prevention. Studies suggest a variety of nutritional influences on prostate cancer risk. The use of Vitamin E may offer some protection. The antioxidant mineral selenium also seems protective. Most Americans get adequate amounts of selenium, but these studies used nutrition supplements, so the study participants achieved higher intake levels. It waits to be seen whether men can protect themselves by taking supplements, including multivitamins, with selenium. If total selenium intake exceeds 400 mcg per day, nerve damage and other side effects can occur in the individual.
Other good foods for natural nutrition are blueberries, broccoli, cabbage, Brussels sprouts, flaxseed, soybeans, and tomatoes. Cooked tomatoes are actually a far better source than raw tomatoes because the cooking process releases the lycopene from cells.

Prostate Cancer Risk Factors
A risk factor is anything that may increase a person's chance of developing a disease. It may be an activity, such as smoking, diet, family history, or many other things. Different diseases, including cancers, have different risk factors. In general, all men are at risk for prostate cancer. However, there are specific risk factors that increase the likelihood that certain men will develop the disease, including the following:Age is a risk factor for prostate cancer, especially men age 50 and older. More than 80 percent of all prostate cancers are diagnosed in men over the age of 65. Race: Prostate cancer is nearly twice as common among African-American men than it is among Caucasian-American men. Japanese and Chinese men native to their country have the lowest rates of prostate cancer.
Diet: Data suggests that the diet consumed in Western industrialized countries may be one of the most important contributory factors for developing prostate cancer. The following information regarding diet and its effect on the risk for prostate cancer include men who eat a high-fat diet may have a greater chance of developing prostate cancer. Dietary fiber intake may decrease the progression of prostate cancer. Soy protein lowers fat intake, and the isoflavones in soy have been found to inhibit the growth of prostate cancer. Vitamin E and selenium Vitamin E, an antioxidant, combined with selenium, has been shown to inhibit tumor growth in laboratory animals. Carotenoids Carotenoids containing lycopenes have been shown to inhibit the growth of human prostate cancer cells in tissue cultures. The primary source of lycopenes is processed tomatoes in tomato juice and tomato paste. Obesity Obesity not only contributes to diabetes and high cholesterol, but has also been associated with some common cancers including prostate cancer.
Vasectomy, BPH (benign prostatic hyperplasia), or STD (sexually transmitted disease) Researchers have looked at whether men who have had a vasectomy, BPH, or those who have had exposure to STD’s are at increased risk for prostate cancer. Some studies suggest a link, while others don’t. Family history of prostate cancer. A father or brother with prostate cancer doubles a man's risk of developing prostate cancer. The risk is even higher for men with several affected relatives. Geneticists divide families into three groups, depending upon the number of men with prostate cancer and their ages of onset, including the following: Sporadic - a family with prostate cancer present in one man, at a typical age of onset. Familial - a family with prostate cancer present in more than one person, but with no definitive pattern of inheritance and usually an older age of onset. Hereditary - Five to 10 percent of prostate cancer cases are considered hereditary. Genetic Approximately 9 percent of all prostate cancers and 45 percent of cases in men younger than age 55 can be attributed to a cancer susceptibility gene that is inherited as a dominant trait (from parent to child).

PROSTATE CANCER
Prostate Cancer is danger which needs to be taken heed by all man. Statistical show 1 from 6 man can experience of prostate cancer and 1 from 35 man die because this cancer. The American Cancer Society estimate in the year 2008 there are 186.320 new case of prostate cancer. Prostate cancer represent cause both of death because cancer at man.- Why only at Man? And what that Prostate Cancer
Prostate Cancer only found at man. Its situation encircle Urethra, channel bringing urine go out from body. Prostate have cells producer of functioning dilution protect and feed cell of sperm. Prostate Gland growing larger below influence of yielded by androgen hormone is testis. This gland will continue to grow reach puberty. Afterward its size measure will be except to fixed man old age. This condition is known as Benign Prostatic Hyperplasia (BPH).
At other condition of prostate cells can grow uncontrollably, referred by condition of cancer. Some risk factor incidence of prostate cancer have succeeded to be identified
- Prostate Cancer very rare happened in age under 40 year but its risk mounts sharply at age above 60 year
- High diet of fat will improve Prostate Cancer risk, whereas rich diet of vegetable and fruit will like watermelon and tomato can degrade it.
- Family history also influences the make-up of Prostate Cancer.
- Can Prostate Cancer cured
Hypodermic therapy of Leuprolide acetate work to depress androgen hormone (hormone required by prostate cancer cells to expand). Giving of hypodermic of Leuprolide acetate each month with dose 3.75 mg can depress activity of prostate cancer equal to 82-89%. READ MORE...
