There are 4 stages of Prostate Cancer
In stage I-Cancer is found in the prostate only
In stage II-Cancer is more advanced than in stage I, but has not spread outside the prostate.
In stage III-Cancer has spread beyond the outer layer of the prostate and may have spread to the seminal vesicles. In stage IV- Cancer has spread beyond the seminal vesicles to nearby tissue or organs, such as the rectum, bladder or pelvic wall or cancer has spread to nearby lymph nodes; or has spread to distant parts of the body, which may include lymph nodes or bones.
