You might also need imaging tests, such as computed tomography (CT) scans, to ensure your cancer hasn’t spread to other areas of your pelvis or abdomen. CT scans use multiple X-ray images to create a 3-D picture of your body.

If your cancer is large or has spread further, you might need chemotherapy before surgery. Chemotherapy uses medicine to destroy cancer cells and shrink cancer, making surgery easier. Radiation therapy uses targeted radiation, like X-rays, to shrink and destroy cancer.
