Prostate cancer affects the prostate gland that is responsible for making the fluid in semen. The prostate is located below the bladder and surrounds a part of the urethra, the tube that drains urine from the bladder. Men are at greater risk for prostate cancer as they age. According to the National Cancer Institute, an estimated 20 percent of men will experience prostate cancer in their lifetimes. While doctors detect most forms of prostate cancer in their earliest stages, prostate cancer can progress. When it spreads to other parts of the body, it’s said to be in the more advanced stages. This diagnosis is not common as doctors diagnose most men in the cancer’s earliest, most treatable stages, according to the Mayo Clinic.
