Types of Uterine Cancer
There are several types of uterine cancer based on where the cancerous cells develop, and if they spread. Your treatment depends on the type of uterine cancer you have.
- Endometrial cancer—the most common type of uterine cancer, starts in the uterine lining (endometrium). According to the American Cancer Society, endometrial cancer tends to develop in women who are at least 60 years old.
