Once testing is complete, your doctor assigns your cancer a stage. This helps determine your treatment options. The prostate cancer stages are:
- Stage I. This stage signifies very early cancer that’s confined to a small area of the prostate. When viewed under a microscope, the cancer cells aren’t considered aggressive.
- Stage II. Cancer at this stage may still be small but may be considered aggressive when cancer cells are viewed under the microscope. Or cancer that is stage II may be larger and may have grown to involve both sides of the prostate gland.
- Stage III. The cancer has spread beyond the prostate to the seminal vesicles or other nearby tissues.
- Stage IV. The cancer has grown to invade nearby organs, such as the bladder, or spread to lymph nodes, bones, lungs or other organs.
