Low-grade squamous intraepithelial lesion (LSIL)

Low-grade squamous intraepithelial lesion (LSIL) is a term used by doctors to describe mild changes in the cells on the surface of the cervix caused by the human papillomavirus (HPV). These changes are usually associated with HPV infections that often go away on their own and are considered early, low-level abnormalities. LSIL is detected through a Pap smear, a screening test, and typically doesn’t cause symptoms. Most cases resolve without treatment, but regular follow-up is important to ensure the cervical cells return to normal and to monitor any changes that might develop into more serious conditions.
