Incidence

The American Cancer Society estimates that there will be 186,320 new cases of prostate cancer diagnosed in the United States in 2008 and that over 28,000 men will die from their disease. The prostate gland is located under the bladder and forms a donut-like collar around the urine channel (urethra). The prostate makes the fluid that helps sperm survive. Sperm are made in the testicles and travel through the vas deferens. They are stored in the seminal vesicles, which are located behind the bladder, just above the prostate gland.

Symptoms

Early prostate cancer has few symptoms, as the disease advances men may experience weak urine flow or other issues with their ability to void urine. The use of the PSA test has enabled physicians to identify prostate cancer cases before symptoms develop.
