Ovarian cancer screening is a way for doctors to look for early signs of ovarian cancer in those who have no symptoms of the disease. To screen for ovarian cancer, doctors can do a blood test called CA 125, an imaging test called an ultrasound, or both. These tests do not always give useful information about whether someone has ovarian cancer. Still, doctors sometimes recommend them for people who are at high risk for ovarian cancer. Experts do not recommend screening for those who are not at high risk.
The goal of screening is to find cancer early, before it has a chance to grow, spread or cause problems. Unfortunately, there is no good proof that screening for ovarian cancer actually helps people live longer.
