What should I know about Prostate Cancer
The cause of prostate cancer is unknown. However, it is known that the growth of cancer cells in the prostate, like that of normal prostate cells, is stimulated by male hormones, especially testosterone. Testosterone is produced almost entirely by the testes (about 95%), with only a small percentage (about 5%) being produced by the adrenal glands (small glands that sit above each kidney).
Compared with other types of cancer, generally, prostate cancer is relatively slow growing. A man with prostate cancer may live for many years without ever having the cancer discovered. In fact, many men with prostate cancer will not die from it but with it. As a man gets older, his risk of developing prostate cancer increases. About 64% of prostate cancers are found in men over the age of 65.1
