Precancerous Cervical Dysplasia

Cervical High-grade Squamous intraepithelial Lesion (HSIL) is a disease of the cervical epithelium, also known as moderate- and high-grade cervical intraepithelial neoplasia (CIN2 and CIN3). HSIL is caused by persistent infection with the cancer-causing human papillomavirus (HPV). HPV infection is common in sexually active women, with a lifetime risk of infection of 75%¹. Most HPV infections are in an incubation period, and most infected individuals clear the virus on their own within three years² . In non-cleared individuals, persistent oncogenic HPV infection may lead to HSIL and invasive cervical cancer.
