This test measures levels of Cancer Antigen 125 (CA 125), a protein often elevated in ovarian cancer and some benign conditions.
Diagnostic Value: Elevated CA 125 can indicate epithelial ovarian cancer or, in some cases, endometriosis, pelvic inflammatory disease, or menstruation-related inflammation.
Clinical Significance: While not diagnostic alone, CA 125 is used to monitor treatment response, detect recurrence, and track disease progression in patients with known ovarian malignancy.
Symptom Correlation: Patients may experience abdominal bloating, pelvic pain, or changes in appetite related to ovarian or pelvic disorders.
Because of its role in detecting early changes during disease management, CA 125 testing is a key biomarker in ovarian cancer monitoring.
