Causes of cervical bleeding

The main causes of cervical bleeding include cervicitis, cervical polyps, cervical intraepithelial neoplasia, cervical cancer, improper uterine operation, endocrine disorders, etc. 1. Cervicitis Cervicitis is one of the more common causes of cervical bleeding. When the cervix is infected by pathogens, such as bacteria, viruses, mycoplasma, etc., causing inflammatory reactions, it will make cervical tissue congestion, edema, easy to bleeding in sexual life, gynecological examination, etc. 2. Cervical polyps The polyps in the cervical canal or in the external mouth of the cervix, the surface of which is covered with columnar epithelium or squamous epithelium, the texture is brittle, easy to rupture bleeding, usually manifested as contact bleeding. 3. Cervical intraepithelial neoplasia cervical intraepithelial neoplasia is cervical precancerous lesions, with the progression of lesions, cervical tissue will become fragile, prone to bleeding symptoms. 4. Cervical cancer early stage may appear contact bleeding, late stage may appear irregular vaginal bleeding. Cancer cells invade cervical tissue, destroy blood vessels and cause bleeding. 5. Improper uterine operation such as abortion, curettage and other uterine operations, if improper operation, may damage the cervix, causing bleeding. 6. Endocrine disorders When estrogen levels fluctuate greatly, it may lead to irregular endometrial shedding, causing a small amount of cervical bleeding.
