Can a CT scan detect ovarian cancer?

A New Treatment for Ovarian Cancer

Best Answer

Computed tomography (CT) scans.

The CT scan is an x-ray test that makes detailed cross-sectional images of your body.

CT scans do not show small ovarian tumors well, but they can see larger tumors, and may be able to see if the tumor is growing into nearby structures.
