What is the definition or description of: ca125?
A doctor has provided 1 answer
CA125 Definition: Ca-125 (cancer antigen 125 or carbohydrate antigen 125) is a biomarker/tumor marker for ovarian cancer (etc); however, it is not sensitive or specific enough to use as a screening test. Also, a uk study showed that treating based on ca125 level did not improve outcomes. "125" comes from the 125th attempt to develop a marker. It was introduced by bast et al. In 1983.
