A woman with a known history of endometriosis experiencing a sudden spike in CA-125 will be evaluated differently than a postmenopausal woman with no risk factors who has a slightly elevated level. This score is particularly useful for women experiencing pelvic pain or bloating, helping to stratify their risk into low, moderate, or high categories.

These tests serve as the indispensable bridge between vague symptoms and a concrete medical reality, providing the data physicians need to move from suspicion to confirmation. This test measures the level of a protein called cancer antigen 125 in the bloodstream.
While imaging provides a visual map, laboratory tests offer a distinct advantage: they can detect molecular-level changes long before a tumor becomes large enough to see. Many benign conditions, such as endometriosis, uterine fibroids, or even severe menstrual cramping, can also raise these levels.

HE4 is a protein that is often elevated in ovarian cancer but is less likely to be raised by benign conditions. This signal prompts a visit to the doctor, where the initial focus often shifts to blood work and imaging.
