| | A common system used by doctors to determine the stage of prostate cancer is the TNM (tumor, node, metastasis) system. Cancer is staged according to:
= the type of tumor
= tumor spread to the lymph nodes
= tumor spread to distant sites
a small tumor that is confined to the prostate, (not detected during a digital rectal exam). This stage of prostate cancer usually produces no symptoms. Treatment may involve observation, surgery to remove the prostate or radiation.
