The CA125 test measures the level of cancer antigen 125 (CA125) in the blood. CA125 is a protein that is often found in higher concentrations in the blood of women with certain types of cancer, particularly ovarian cancer. Overall, the CA125 test is a valuable tool for detecting and managing ovarian cancer, especially when used as part of a comprehensive diagnostic and monitoring strategy. It helps guide treatment decisions, monitor response to therapy, and detect recurrences early, contributing to better patient outcomes.
