What is uterine and endometrial cancer?

Uterine cancer is a disease in which cancer cells form in the tissues of the uterus (womb). There are two primary types of uterine cancer: endometrial cancer, which is more common, and uterine sarcoma, which is rare. In endometrial cancer, cancer cells form in the endometrium, which is the lining of the uterus.

Types of uterine and endometrial cancer

  • Endometrioid adenocarcinoma. This is the most common form of uterine and endometrial cancer. It forms in the glands of the endometrium and varies in severity.
  • Uterine papillary serous carcinoma. This is an aggressive yet more rare form of uterine and endometrial cancer that forms in the lining of the uterus. It tends to return, even when caught early.
  • Uterine clear cell carcinoma. This is an even more rare form, making up fewer than 5 percent of cases.
  • Uterine carcinosarcoma. This is another rare yet typically more aggressive form of uterine and endometrial cancer. It makes up fewer than 5 percent of cases.
  • Uterine sarcoma. Uterine sarcoma develops in the muscle wall of the uterus, also called the myometrium. Fewer than 10 percent of uterine cancer cases are uterine sarcoma. Uterine sarcomas are often more aggressive than other types of uterine cancer.
