Dennis R. Scribner, MD, FACOG, FACS, clinical associate professor for the University of Arizona School of Medicine, Arizona Oncology, explains an important telltale sign of uterine cancer.
While there is no test for uterine cancer (such as a mammogram for breast cancer or a colonoscopy for colorectal cancer) vaginal bleeding is one of the first signs that a woman might have uterine cancer. so, Scribner suggests that women who are experiencing abnormal bleeding contact their health care providers.
