No special measures are known to prevent the development of prostate cancer. At present, therefore, we hope only to prevent the progression of cancer by providing early diagnosis and then try to cure the disease. Early diagnosis can be done to screen men for prostate cancer with PSA and DRE goal of screening is to detect cancers early, small or even microscopic who are confined to the prostate. Early treatment of these malignancies (cancers) can stop growth and prevent their spread, and possibly cure cancer.
Based on research in animals and humans, a certain diet was suggested to prevent progression of prostate cancer. For example, low fat, particularly avoiding red meat, has been suggested because they are thought to slow the growth of prostate tumors in a manner not yet known. Soy products, which works by reducing testosterone levels in the blood, would also can inhibit the growth of prostate tumors. Finally, other studies show that tomato products (lycopene), selenium and vitamin E may slow the growth of prostate tumors in a not yet understood.
Recently, studies have shown that certain medications (finasteride [Propecia] and dutasteride [Avodart]) reducing the chances of having a prostate cancer when taken long term. These drugs are currently used to reduce the size of the prostate and relieve symptoms associated with benign (not cancerous) prostate cancer. They may have a future role in reducing the risk of developing prostate cancer in men at high risk for the disease.
