cin3 refers to cervical intraepithelial neoplasia grade III, currently known as squamous intraepithelial lesion grade III. Squamous intraepithelial lesion grade III is usually fine after removal of the uterus, but it needs to be reviewed in time. Squamous intraepithelial lesion grade III is a precancerous cervical lesion, which may be related to HPV infection and autoimmune function abnormality to a certain extent, but it has not developed into cervical cancer, and the removal of the uterus after the patient has been sick can avoid the continuous development of the disease, so the patient will usually be fine after the removal of the uterus. After the operation, patients need to pay attention to personal hygiene, avoid unclean sex, and go to the hospital for regular checkups to observe the postoperative recovery. Squamous intraepithelial lesion grade III requires timely treatment and review to avoid further progression of the disease.
