Prostate Cancer

What is Prostate Cancer?

Prostate cancer is a disease that begins in the prostate gland when normal prostate cells begin to show new properties and take on a different appearance and behavior. If prostate cancer cells are viewed under a microscope, they look nothing like kidney, colon, lung or any other type of cancer cell. Whereas normal prostate cells are incapable of growing in other parts of the body, prostate cancer cells have the ability to invade and spread into other organs. This process is called metastases. The development of metastases is what makes cancers so dangerous and life-threatening.

When prostate cancer cells grow and then spreads to other parts of the body, they still have most of the same properties and appearance as when it first developed. It is not a new cancer. For example, when prostate cancer spreads into the bones, it is still called prostate cancer rather than bone cancer.
