Prostate cancer is a type of cancer that develops in the prostate gland, a small walnut-shaped gland in men that produces seminal fluid.

Prostate cancer is a disease in which cells in the prostate gland grow abnormally and form a tumor.

The prostate is a small gland in men, about the size of a walnut, located below the bladder and in front of the rectum. It helps produce fluid that mixes with sperm to make semen.

What it is

• Prostate cancer happens when cells in the prostate grow uncontrollably.
• It’s one of the most common cancers in men, especially after age 50.
• Many prostate cancers grow slowly, but some can be aggressive.

Symptoms (often none at early stages)

• Trouble urinatingg (weak stream, frequent urination, especially at night)
• Blood in urine or semen
• Erectile dysfunction
• Pain in hips, back, or chest (if cancer spreads)
• Many men don’t notice symptoms until later stages.

Outlook

• Many prostate cancers grow slowly and may never cause serious problems.
• When caught early, the survival rate is very high.
• Advanced prostate cancer can spread (metastasize), most often to bones.
