The endometrium is the lining of the uterus that periodically thickens and sheds during a woman’s reproductive years. When menopause occurs, this cycle is ended and hormone changes ensue. Consequently, postmenopausal women are at greater risk for certain adverse health conditions, including endometrial neoplasms, which are the most common and most readily cured kind of uterine cancers. Approximately 40,000 American women are diagnosed with endometrial cancer each year, and when caught early, the five-year survival rate for patients is greater than 90 percent. Adenocarcinomas, which originate in epithelial cells and exhibit gland-like characteristics, account for most cases of the disease.
