CIN 1

A cervical biopsy finding that means slightly abnormal cells were found on the surface of the cervix. CIN 1 is usually caused by infection with certain types of human papillomavirus (HPV). CIN 1 is not cancer and usually goes away on its own without treatment, but sometimes it can become cancer and spread to nearby normal tissue. CIN 1 is sometimes called low-grade or mild dysplasia. Also called cervical squamous intraepithelial neoplasia 1.
