Prostate Cancer

A small gland in the male reproductive system called the prostate makes the fluid that carries and nourishes sperm. This gland, which is about the size of a walnut, can develop cancer when some of its cells grow abnormally. Prostate cancer is among the most common cancers in men.

Signs and Symptoms

Early-stage prostate cancer usually causes no symptoms. More advanced prostate cancer might cause:

• Difficulty urinating or decreased force in the stream of urine
• Blood in the urine or semen
• Bone pain
• Erectile dysfunction

Clinical Progression

Prostate cancer can grow slowly or aggressively. Aggressive types can spread quickly to other organs.
