It is normal to have menstruation in early stage of cervical cancer because the lesion is localized in the cervix and menstruation is caused by the shedding of the endometrium. When the early stage of cervical cancer does not invade the endometrium and other tissues, menstruation is still regular at this time and the time of menstruation is also normal. Early symptoms of cervical cancer are relatively few, and some people may experience contact bleeding during intercourse. Once contact bleeding occurs, go to the hospital for cervical cancer screening in time, and if necessary, colposcopy can be done to make a preliminary diagnosis. If you have abnormal menstruation, you should go to the hospital for examination to understand the cause and then give adjustment, and women should have cervical cancer screening once a year.
