Early on, cervical cancer may not cause signs and symptoms. As it advances, it may cause symptoms that call for medical attention. “You should see your gynecologist immediately if you have symptoms, such as a significant change in your discharge, if discharge smells bad or has a brown or pink color, if there is pain or bleeding outside of your usual menstrual cycle, if your cycles become irregular, or if you have been through menopause and have any vaginal bleeding even if spotting or light,” Dr. Janco says.
