Prostate Cancer Cells

Cancer begins in cells, the building blocks that make up tissues. Tissues make up the organs of the body.

Normal cells grow and divide to form new cells as the body needs them. When normal cells grow old or get damaged, they die, and new cells take their place.

Sometimes, this process goes wrong. New cells form when the body doesn't need them, and old or damaged cells don't die as they should. The buildup of extra cells often forms a mass of tissue called a growth or tumor.

Prostate growths can be benign (not cancer) or malignant (cancer).

Benign growths are not as harmful as malignant growths:

* Benign growths (such as BPH):
o are rarely a threat to life
o can be removed and probably won't grow back
o don't invade the tissues around them
o don't spread to other parts of the body

* Malignant tumors:
o may be a threat to life
o often can be removed, but sometimes grow back
o can invade and damage nearby tissues and organs
o can spread to other parts of the body

Cancer cells can spread by breaking away from the prostate tumor. They enter blood vessels or lymph vessels, which branch into all the tissues of the body. The cancer cells can attach to other tissues and grow to form new tumors that may damage those tissues. The spread of cancer is called metastasis. See the Staging section for information about prostate cancer that has spread.
