When a woman has cervical bleeding, she needs to go to a hospital gynecology department for an internal examination to confirm the exact cause of the bleeding and then treat the symptoms. There are many reasons for cervical bleeding, including cervical erosion, cervical polyps, cervical intraepithelial neoplasia, or even cervical cancer, and in the case of women who give birth in normal labor, the cervical cervix may be torn during the process, causing heavy bleeding. If the bleeding is caused by cervical erosion, contact bleeding after intercourse is usually a physiological displacement of the columnar epithelium, so it can be treated vaginally with povidone suppositories, and if the bleeding is caused by cervical polyps, the polyps are usually benign lesions, so it is not serious and can usually be considered for surgical removal. 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 necessary to seek immediate medical attention at that time because the cancer cells may spread and even endanger the woman’s life.
