Since the causes of cervical bleeding are different, its exact severity varies from person to person. If the bleeding is caused by cervical erosion, it is usually not serious, but if it is caused by cervical cancer, it is more serious. There are many reasons for women to have cervical bleeding, it may be caused by cervical erosion, cervical polyp, cervical intraepithelial neoplasia, or even cervical cancer. If the bleeding is caused by cervical erosion, contact bleeding after intercourse is usually not serious because cervical erosion is usually a physiological displacement of the columnar epithelium, so it can be treated vaginally with povidon suppositories. If the bleeding is caused by cervical intraepithelial neoplasia, it may develop into cervical cancer, so cervical conization surgery is usually required, but since it is not cancerous at present, it is usually not life-threatening and therefore not serious. If it is caused by cervical cancer, it is more serious at this point because the cancer cells may spread and even endanger the woman’s life. Therefore, when a woman has cervical bleeding, she needs to go to the gynecology department of the hospital for an internal examination to confirm the specific cause of the bleeding and then treat it symptomatically.
