Biochemical recurrence

From Wikipedia, the free encyclopedia

Biochemical recurrence is a rise in the blood level of PSA (prostate-specific antigen) in prostate cancer patients after treatment with surgery or radiation. Biochemical recurrence may occur in patients who do not have symptoms. It may mean that the cancer has come back. Also called PSA failure and biochemical relapse.
