Low CA-125: what it means

- Low or normal CA-125 does NOT rule out ovarian cancer in a symptomatic woman; complementary imaging and clinical work-up are needed.
When to discuss with a doctor
If you have CA-125 ordered in the context of a known ovarian cancer or with concerning gynaecological symptoms (persistent bloating, abdominal pain, early satiety), the result belongs in conversation with your gynaecologist or oncologist. An incidentally elevated CA-125 in a woman without symptoms is far more likely to reflect a benign cause; Mediora.AI shows the value with the benign-vs-malignant context but cannot make this call alone.
