What It Is

Normally the growth of all cells is carefully controlled in the body. As cells die, they are replaced in an orderly fashion. When cancer develops, the cells start to multiply in an uncontrolled way.

If this happens in the prostate gland, prostate cancer can develop. In most cases this is a slow growing cancer and it may stay undiagnosed because it never causes any symptoms or problems. However, this is not true for all men. Sometimes prostate cancer cells can grow quickly and move outside the prostate. They may then cause symptoms in other parts of the body, such as the bones.
