Prostate Cancer

Prostate cancer is cancer of the prostate gland, which produces much of the fluid that makes up semen. Early prostate cancer usually doesn't cause any symptoms, but more advanced symptoms include difficulty urinating, blood in the urine, or impotence. Many cases of prostate cancer are not immediately treated but monitored closely for signs of growth or disease advancement. In some cases, prostate cancer is treated with surgery, radiation therapy, cryotherapy, hormone therapy, chemotherapy, and/or vaccine therapy. The survival rate for prostate cancer varies depending on the stage of diagnosis, type of treatment, and other factors.
