Uterine Cancer & Endometrial Cancer Types
Adenocarcinoma, which originates in surface cells of the endometrium, accounts for approximately 90 percent of cases of endometrial cancer. Adenocarcinomas are more common during perimenopause (i.e., transitional years preceding and following actual menopause) and usually are associated with an early onset of symptoms.
Other types of endometrial cancer include papillary serous carcinoma and clear cell carcinoma. These types usually develop in postmenopausal women and are more likely to metastasize (spread) and recur.
Types of uterine sarcoma include carcinosarcoma (most common type), leiomyosarcoma (develop in the muscular tissue of the myometrium), and endometrial stromal sarcoma (develop in supporting connective tissue).
