Small granules at the mouth of the cervix may be caused by ectropion of the cervical columnar epithelium during cervical erosion thus causing local hyperplasia, which manifests as small granules when touched. It may also be a cervical canal polyp, resulting in small particles. The specific conditions and treatments are as follows: 1. Cervical erosion: cervical columnar epithelium ectropion causing local hyperplasia, even granular, resulting in small granule-like growths at the cervical opening. Through HPV and TCT examination to exclude other cervical lesions, generally do not need treatment, regular screening cervical lesions can be; 2, cervical polyp: cervical infection, chronic inflammation caused by cervical tissue proliferation, resulting in cervical confined hyperplasia, the formation of polyps, usually red, purple or off-white, the shape may be like a finger, bulb or thin stem, polyps protrude from the cervical opening, manifested as small granular. The main treatment for cervical polyps is surgery, such as polyp removal, post-operative application of painkillers and hemostatic drugs to aid recovery, as well as good personal hygiene to prevent polyp infection and recurrence. 3, cervical naevus: small particles at the mouth of the cervix may be caused by cervical naevus, which is visible as greenish-white vesicles protruding from the surface of the cervix, containing mucus, small as rice grains, large as corn grains, protruding from the surface of the cervix and even reaching the vaginal opening. Patients who do not have uncomfortable symptoms usually do not need to be treated, with inflammation to be treated with drugs or physical therapy, cervical naevus is rare huge, can be treated surgically. Attentions appearing small particles of cervical opening can be temporarily observed, but attention should be paid to regular gynecological examinations to detect abnormalities and deal with them in time; symptoms such as abnormal bleeding and abnormal discharge should be sought in time to avoid delaying the condition.
