stage I prostate cancer(...PROS-tayt KAN-ser)
Cancer is found in the prostate only. The cancer (1) is found by needle biopsy or in a small amount of tissue during surgery for other reasons; the prostate-specific antigen (PSA) level is lower than 10 and the Gleason score is 6 or lower; or (2) is found in one-half or less of one lobe of the prostate; the PSA level is lower than 10 and the Gleason score is 6 or lower; or (3) cannot be felt during a digital rectal exam and is not visible by imaging; cancer is found in one-half or less of one lobe of the prostate and the PSA level and Gleason score are not known.
As prostate cancer progresses from Stage I to Stage IV, the cancer cells grow within the prostate, through the outer layer of the prostate into nearby tissue, and then to lymph nodes or other parts of the body.
