What is LSIL?
You may hear low-grade squamous intraepithelial lesion (LSIL) being referred to as LGSIL or a low-grade abnormal Pap smear. Unusual cell growth is caused by certain strains of the human papillomavirus (HPV). Upon microscopic examination, these squamous cells will display mild dysplasia or abnormalities.
The presence of intraepithelial lesions is extremely common in Pap screenings and does not indicate cancer. In fact, the overall likelihood of patients with LSIL getting cancer is less than 1%.
