Prostate Cancer Overview


Prostate cancer is the most common form of cancer among men in the United States, and is the second-leading cause of cancer death in men, after lung cancer. Prostate cancer is a disease in which the cells of the prostate begin to grow uncontrollably, forming tumors. A tumor is a mass or lump of tissue made of abnormal cells that can eventually spread, or metastasize, from the prostate to other parts of the body. The most common sites to which it spreads are the lymph nodes, the lungs, and bones.

While some prostate cancers can grow and spread quickly, many prostate cancers grow slowly. In fact, autopsy studies show that many older men who died of other diseases also had undiagnosed prostate cancer that did not contribute to their death.

As with many forms of cancer, early detection of prostate cancer greatly increases the chances of survival. Regular check-ups and screenings, especially after age 50, are very important.
