What factors are used to assess the success of prostate cancer treatment?
After treatment for prostate cancer, a physician will monitor the disease carefully, checking to see if the cancer recurs or spreads further. A physician uses both a prostate-specific antigen test (PSA) and prostate biopsies following treatment to keep the cancer in check (see Fact Sheet for explanation of PSA). The PSA test can detect elevated levels of the PSA protein while a biopsy shows if cancer is present in the prostate tissue.
