what are the causes of prostate cancer
The exact cause of the prostate cancer still remains unknown. The risk factors that contribute to the prostate cancer are advanced age, hereditary, environmental effects like the exposure to toxic chemicals and industry products. People aged above 40 are more prone to this type of cancer and rare in people below the age of 40. The hereditary plays a vital role in the development of prostate cancer. For instance, the black people are more vulnerable to prostate cancer than the white people. These genetic propositions can be modified by a number of factors such as the diet and environment. For instance, if a Japanese lives in Japan, then he is less prone to prostate cancer than when he lives in America. Prostate cancer commonly develops in the individual who have family background with prostate cancer. At present there are no proofs of the genes that are responsible for the development of prostate cancer. Both the prostate tissues and the prostate cancer cells are directly stimulated by

Like breast cancer, prostate cancer is particularly sensitive to factors that influence hormone levels. Concern that vasectomy may increase the risk of prostate cancer stems from the conflicting results of a number of studies. The studies that started the controversy were published in 1993, and reported that men who underwent vasectomy had a very small – 1.5 percent – increase in risk. More recently, another large study compared 753 men with prostate cancer to 703 men who didn’t have the disease. After adjusting for age, race (African Americans have twice the risk of whites) and family history of the disease, they found that among those with prostate cancer 39.4 had vasectomies compared with 37.7 percent of those who didn’t have cancer. Such a small difference suggests that there r
