Additional Study Information: The purpose of this study is to collect vaginal, cervical, and uterine samples for the study during your scheduled surgery. The samples will be collected using cell collection tools similar to how samples are collected during your regular pelvic exams, such as a pap smear to develop a collection method for endometrial sampling which is less invasive and less painful than the current sampling method and develop a test which can be used to identify those patients who are benign for uterine cancer with similar accuracy as current diagnostic methods. This could greatly reduce the patients requiring invasive endometrial sampling per the current standard of care.
