Cervical cancer bleeding is usually manifested as supracervical bleeding, but supracervical bleeding is not necessarily due to cervical cancer, cervical inflammation, cervical columnar epithelial ectasia and so on can cause supracervical bleeding. Bleeding from cervical cancer is usually caused by contact bleeding or vaginal bleeding due to exposure of blood vessels or shedding of cancerous tissues, etc., all of which belong to supracervical bleeding. However, cervical polyps, cervical columnar epithelial ectasia, cervical cysts and other diseases can also cause cervical bleeding. Therefore, if cervical bleeding occurs, it should be diagnosed under the examination of relevant pathology, and should not be blindly presumed and treated. Cervical cancer is a very serious disease, usually manifested as bleeding on the cervix, so if symptoms of cervical bleeding occur, it is necessary to go to the hospital for examination and consultation in time to promote the alleviation of the condition.
