Overview

Uterine cancer, also known as endometrial cancer, is a disease that forms in the endometrium, which is the tissue lining the uterus. Type 1 endometrial carcinomas are associated with obesity and excess estrogen; they tend to present at an early stage and have a better prognosis. Type 2 endometrial carcinomas are not due to estrogen stimulation and are more likely to be higher grade with a poorer prognosis.

Uterine cancers that start in the muscle layer or connective tissue belong to another group of cancers called sarcomas. Cervical (uterine cervix) cancer begins in the cervix and can spread to the uterus, but is distinct from uterine cancer that starts in the uterus itself.
