Cancer is more advanced than in stage I, but has not spread outside the prostate. Stage II is divided into stages IIA, IIB, and IIC. In stage IIA, cancer (1) is found in one-half or less of one side of the prostate. The prostate-specific antigen (PSA) level is at least 10 but lower than 20 and the Grade Group is 1 (Gleason score is 6 or less); or (2) is found in more than one-half of one side of the prostate or in both sides of the prostate. The PSA level is lower than 20 and the Grade Group is 1. In stage IIB, cancer is found in one or both sides of the prostate. The PSA level is lower than 20 and the Grade Group is 2 (Gleason score is 7). In stage IIC, cancer is found in one or both sides of the prostate. The PSA level is lower than 20 and the Grade Group is 3 or 4 (Gleason score is 7 or 8).
