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.
This process is called staging. The stage of a prostate cancer describes how much cancer is in the body. It helps determine how serious the cancer is and how best to treat it. Doctors also use a cancer’s stage when talking about survival statistics.
Stage IV: The cancer has spread beyond the prostate. Stage IVA: The cancer has spread to the regional lymph nodes (any T, N1, M0, any PSA, any Grade Group). Stage IVB: The cancer has spread to distant lymph nodes, other parts of the body, or to the bones (any T, N0, M1, any PSA, any Grade Group).
