Prostate Cancer

Prostate Cancer
by: Seth Miller
The prostrate is a gland found only in males and located in front of the rectum, on the neck of the bladder. It is a walnut-sized gland about 3 cm in size that encircles the urethra. The prostrate produces seminal fluids and, along with the sperm received from the testes, releases the semen into the urethra during ejaculation. It also prevents the semen from flowing back into the bladder.

Prostrate cancer starts quite late in life; the number of persons who have prostrate cancer but are dying of other causes is large. One in 6 American males is likely to get prostrate cancer but only one in 32 dies of it.
