Uterine cancer is the most prevalent type of reproductive system cancer in women. It develops when the healthy cells of the uterus transform and grow uncontrollably to form a tumor. Uterine cancer is classified into two categories: adenocarcinoma and sarcoma. Adenocarcinoma develops from the endometrial cells and accounts for more than 80% of uterine cancers. This is commonly known as endometrial cancer. One common form of endometrial adenocarcinoma is endometrioid carcinoma, for which the treatment depends on the grade of the tumor, the stage or the extent of the disease, and how far the tumor goes into the uterus. A less common form of endometrial adenocarcinoma is endometrial serous carcinoma. Sarcoma develops in the uterine glands’ supporting tissues or in the myometrium, and accounts for approximately 2–4% of uterine cancers. Types of endometrial sarcoma include endometrial stromal sarcoma and leiomyosarcoma.
