   • Stage 1 is the least advanced form of prostate cancer. Cancer in this stage is small and hasn’t spread past the prostate gland. It’s characterized by a PSA of less than 10 ng/mL, a grade group score of 1, and a Gleason score of 6.
   • In stage 2, the tumor is still confined to your prostate and hasn’t spread to lymph nodes or other parts of your body. A doctor may or may not be able to feel the tumor during a prostate exam, and it may appear on ultrasound imaging.
   • At stage 3, cancer cells may or may not have spread outside the prostate to other tissues. The survival rate of prostate cancer that hasn’t spread to distant parts of your body is still close to 100 percent.
   • Stage 4 is the most advanced stage of prostate cancer and is divided into two letter groups. Stage 4 prostate cancer can have any grade group, PSA value, and Gleason score.
