Biochemical Recurrence

Meaning

Biochemical Recurrence is the measurable increase of a specific tumor marker in the bloodstream following definitive treatment for a malignancy, signaling the potential return of the disease at a cellular level. For example, in prostate health, this term specifically refers to a rise in Prostate-Specific Antigen (PSA) after surgery or radiation therapy. This elevation serves as a crucial, early diagnostic signal that typically precedes any clinical or radiological evidence of disease recurrence. Monitoring these quantitative markers allows for timely clinical intervention and strategic adjustment of personalized wellness protocols.
