Bleeding during intercourse is the first of several things to consider. First, it is inflammation of the cervix. If the cervix is inflamed, the tissue is relatively fragile, in the coitus, external forces may appear vaginal bleeding. Second, is there cervical redundancy, the most common is the cervical polyp, after intercourse will also cause a little bleeding. Third, cervical cancer. Cancer of the cervix is most likely to vaginal bleeding, the earliest clinical manifestation of cervical cancer is a little vaginal bleeding after intercourse. If you want to exclude the above situations, you should go to the hospital for examination. If there are polyps, we need to perform cervical polyp removal; if there is cervical inflammation or suspected pre-cancerous cervical lesions, we need to perform cervical cancer screening, cervical cancer screening includes cytology and viral examination.
