The problem: The biggest concern with postcoital bleeding is that it is a sign of cervical cancer. Fortunately, that is rare in young women – about 3-5% of women worldwide who bleed after sex have cervical cancer. However, up to 18 percent have cervical intraepithelial neoplasia (CIN), a precancerous condition in which abnormal cells grow on the surface of the cervix, according to a 2014 review in Obstetrics and Gynecology International. That is why you should inform your doctor about any problems.
The Solution: “Cervical cancer is a disease that we can almost completely prevent from women receiving the HPV vaccine,” says Dr. Minkin. In fact, the current formula protects you from about 90 percent of cervical cancers; therefore, if you have not already had it, talk to your doctor.
