Are there types of uterine cancer?
In general, there are 2 types of uterine cancer. The most common type, endometrial carcinoma, forms in the lining of the uterus and is often related to prolonged exposure to estrogen (typically in the absence of progesterone). Estrogen exposure in this fashion can occur due to a variety of reasons including being overweight, as well taking medications (estrogen replacement therapy without progesterone), or due to production of estrogen by your own body. The second type is uterine sarcoma, which is a much less common form and may arise from the uterine muscle (myometrium) or from the support tissue (stroma) within the uterus.
