Once testing is complete, your doctor assigns a stage to your cancer. This helps guide your treatment options. The stages of prostate cancer are:

  • Stage I: Cancer is confined to a small area within the prostate. Under the microscope, the cancer cells appear non-aggressive.

    Stage II: Cancer may still be small but looks aggressive under the microscope, or it may be larger and involve both sides of the prostate gland.

    Stage III: Cancer has spread beyond the prostate to the seminal vesicles or nearby tissues.

    Stage IV: Cancer has invaded nearby organs (such as the bladder) or spread to lymph nodes, bones, lungs, or other distant sites.
