What Is Prostate Cancer?
Prostate cancer is a malignant (cancerous) tumor growth that comprises of cells of the prostate gland. The tumor normally grows slowly and remains confined to the gland for many years. As the cancer advances, however, it can spread beyond the prostate into the surrounding tissues (local spread). Moreover, the cancer also can metastasize (spread even further) to other areas of the body such as bones, lungs and liver.
