ENDOMETRIAL CANCER: A guide for patients patient information based on ESMO clinical practice gudielines
DEFINITION OF ENDOMETRIAL CANCER
This definition comes from and is used with the permission of the National Cancer Institute (NCI) of the United States of America. Cancer that forms in the tissue* lining the uterus (the small, hollow, pear-shaped organ in a woman's pelvis in which a fetus develops). Most endometrial cancers are adenocarcinomas* (cancers that begin in cells that make and release mucus and other fluids).
Important note regarding other types of cancer of the uterus
Cervical cancer Cervical cancer is a cancer forming in the cervix of the uterus, unlike endometrial cancer which forms in the corpus of the uterus. Diagnosis and treatment of this type of cancer is different from endometrial cancer.
Uterine sarcoma* Uterine sarcoma* is another type of cancer forming in the corpus of the uterus. It forms in the muscle of the uterus (myometrium) or in other tissues* in the uterus. Although the treatment of uterine sarcoma* and endometrial cancer have some similarities, the information presented here is valid for endometrial cancer but not for uterine sarcoma*.
Uterine carcinosarcoma* Uterine carcinosarcoma is a type of cancer forming in the corpus of the uterus. It is now acknowledged that carcinosarcoma may be a type of aggressive endometrial cancer. The information provided on endometrial cancer is therefore also valid for uterine carcinosarcoma
