Ca 125 (Ovarian Cancer Marker)

The CA 125 test is a critical tool used to monitor the progression of ovarian cancer and assess the effectiveness of treatment. By measuring the concentration of the CA 125 protein in the blood, healthcare providers can gain critical insights into whether a tumor is shrinking, stable, or recurring, often detecting changes before they are visible on imaging scans. For individuals at high risk due to family history or genetic markers, it serves as a helpful supplemental indicator, though it is most powerful when used to track known cases. Ultimately, this test provides a measurable roadmap for oncology teams to refine treatment plans and improve patient outcomes.
