Cervical precancerous lesions are also known as squamous intraepithelial lesions, and the development of the disease is associated with persistent infection with high-risk types of human papillomavirus. For treatment, precancerous cervical lesions are usually surgically removed immediately after diagnosis because of their tendency to become cancerous. The two main types of surgery for precancerous cervical lesions are cervical conization and total hysterectomy. Cervical conization is usually performed on younger patients with reproductive needs. This procedure removes only the cervical cancerous lesions, preserving the uterus and ovaries. Total hysterectomy is for older patients who have no need for childbearing. This procedure removes the cervical cancer as well as the uterus, but also preserves the ovaries. If you are diagnosed with precancerous cervical lesions, follow your doctor’s instructions.
