Breast cancer is a persistent disease that starts when cells in the breast grow out of control, usually forming a mass (tumor). If the tumor is cancerous (malignant), the cells can invade surrounding tissues or spread (metastasize) to distant areas of the body.
Prostate cancer is one of the common cancers affecting Americans. The disease occurs when cells in the prostate gland grows abnormally.
Prostate glands are unique to males and responsible for generating some of the fluid in the semen. It is about the size of a walnut, but it may grow bigger in size as a male person ages. It is located near the urethra and the bladder.
