Endometrial cancer is cancer that starts in the endometrium, or inner lining of the uterus the hollow, pear-shaped organ that is part of your reproductive system. It is sometimes also referred to as uterine cancer. Endometrial cancer usually occurs after natural menopause, with 60 being the average age at diagnosis. Other symptoms include unusual pelvic pain or pressure, difficult or painful urination, and pain during intercourse. The breast cancer treatment tamoxifen sometimes called by its brand name, Nolvadex increases the risk of developing endometrial cancer, but not nearly enough to outweigh its benefits against breast cancer in most women.
