What is prostate cancer?

Prostate is part of the male reproductive system.  It is a walnut-shaped gland located between the bladder neck surrounding the urethra.  The main function of the prostate is to secrete a milky white liquid into the semen and sperm to help sperm injection in vitro.
In general, men over the age of 50 are more likely to have prostate cancer.  Prostate cancer and the occurrence of cancer in other parts of the body is slightly different. If the cancer occurs only in small part of the prostate, the cancer cells can remain unchanged for some time before it starts to spread and grow.  Cancer cells can be found in prostates among approximately one-third of men over the age of 50. Cancer cells can mostly be found in all men over 80.  These cancer cells can grow in a very slow pace, especially in the elderly, and it may never turn into cancer. Though, in certain  cases, the cancer cells can grow fast and spread to other parts of the body, such as bone marrow.
