Vitamin E and Prostate Cancer

Does vitamin E prevents prostate cancer or not, that's the question in highlight for some researchers from Harvard. The U.S. Preventive Services Task Force recently recommended against routine vitamin use to prevent cancer and cardiovascular disease. The recommendation was based on a series of clinical trials. However, just a few weeks later, results from a trial showed that men with high blood levels of alpha-tocopherol (a form of vitamin E) had a lower risk of prostate cancer, reports Harvard Men's Health Watch.

"The ATBC research provides some support for vitamin E, but it's not conclusive," notes Dr. Harvey Simon, editor in chief of Harvard Men's Health Watch. "Although it was a well-conducted clinical trial, its primary goal was to evaluate lung cancer. More important, all the subjects were smokers." A few other studies looked into this matter and found that vitamin E was not consistently beneficial in reducing the risk of prostate cancer in smokers and nonsmokers.

The relationship between vitamin E and prostate cancer has yet another complexity. Vitamin E consists of a family of chemicals known as tocopherols. Alpha-tocopherol, the form usually found in supplements, is most common. But another tocopherol, gamma-tocopherol, which is found in foods but not normally in supplements, may have an impact on prostate cancer. Studies disagree, however, on which form has the greatest effect.

Should you use antioxidants to reduce your risk of prostate cancer? The Harvard Men's Health Watch reports that despite the encouraging ATBC results, there is not enough evidence at present to warrant widespread use of any form of vitamin E for prostate cancer risk reduction. But while supplementation does not seem wise, there's plenty of support for getting lots of antioxidants from foods.

Prostate cancer
The prostate is located just below the bladder and in front of the rectum in male. The tube that carries urine runs through the prostate. The prostate contains cells that make some of the seminal fluid. This fluid protects and nourishes the sperm. Prostate cancer usually starts in the gland cells of the prostate. This kind of cancer is known as adenocarcinoma. Prostate cancer is usually a slow disease, but sometimes it can grow fast and spread quickly to other organs.
