Specific cause of prostate cancer has not definitely known. A man whose prostate cancer risk associated with age, genetics, race, diet, lifestyle, and medications. The main risk factor is age. Prostate cancer occurs less in men aged less than 45 years, but could increase the possibility with the addition of age. The average age at time of diagnosis is 70 years old.
Genetic influence on the development of prostate cancer can be seen from the increase in the incidence of prostate cancer in a particular race, male identical twins and have prostate cancer, and men with certain genes. The U.S. study showed that prostate cancer is more often attacked black men than white men or men of Spain and more deadly when attacking a black man. Men who have a brother or father with prostate cancer have twice the likelihood of prostate cancer. Research in the male twins in the Scandinavian states that 40% risk of prostate cancer can be explained by innate factors. However, not only single genes responsible for prostate cancer; many different genes that affect. Two genes (BRCA1 and BRCA2) which is an important risk factor for ovarian cancer and breast in women cancer also play a role for prostate cancer.
A diet of foods, vitamins, and minerals can contribute to the risk of prostate cancer. Men with serum levels of short-chain ?-6 fatty acid linoleic acid which has increased the incidence of prostate cancer is higher, while increasing levels of long chain ?-3 (EPA and DHA) had a lower incidence. Trans fats are the hydrogenated vegetable oil related with increased risk of prostate cancer. Another factor that could increase the risk of prostate cancer is low consumption of vitamin E (vitamin E found in green leafy vegetables), omega-3 fatty acids (found in fatty fish like salmon), and selenium. Low levels of vitamin D in the blood can also increase the risk of prostate cancer.
