Biochemical recurrence
Biochemical Recurrence
Biochemical recurrence (pronunciation: /ˌbaɪoʊˈkɛmɪkəl rɪˈkɜrəns/) is a term used in the field of oncology to describe the return of cancer after treatment, as indicated by rising levels of specific biomarkers in the blood.
Etymology
The term "biochemical recurrence" is derived from the words "biochemical", referring to the chemical processes and substances occurring within living organisms, and "recurrence", meaning the return of a medical condition after a period of improvement.
Definition
Biochemical recurrence is defined as the return of cancer, specifically prostate cancer, after treatment, as indicated by a rise in the level of prostate-specific antigen (PSA) in the blood. This rise in PSA level is often the first sign of recurrence, even before any physical symptoms or imaging tests show evidence of disease.
