Carrying even an extra 30 pounds significantly increases a woman's risk for endometrial cancer, the most common cancer of the female reproductive organs. Abnormal vaginal bleeding is the chief symptom, but too many women are unsure what's normal and abnormal. Mary Cunningham, MD, explains bleeding patterns during menopause and when to see a doctor. She also goes over the diagnosis and treatment options for endometrial cancer. Cunningham, a professor of obstetrics and gynecology, is the chief of gynecologic oncology at Upstate.
