CA125
Also called Cancer antigen 125
CA125 is a protein blood test clinicians sometimes use when investigating ovarian cancer symptoms or monitoring some high-risk surveillance plans.
Levels can rise with ovarian cancer, but also with endometriosis, fibroids, infection and pregnancy. Doctors pair it with imaging and examination; it is not a standalone screening test for the general public in the UK.
