Cervical precancer (CIN, HSIL/LSIL)
Abnormal cervical cells caused by HPV that can turn into cancer over 10-20 years. Screening finds them; a five-minute procedure removes them.
Cervical intraepithelial neoplasia grades 1-3, now reported as low-grade (LSIL, CIN1) or high-grade (HSIL, CIN2-3) squamous intraepithelial lesions; adenocarcinoma in situ is the glandular equivalent. Most LSIL regresses; ~30% of untreated CIN3 progresses to cancer within 30 years. Treated by LEEP/LLETZ excision, cold-knife cone, cryotherapy, or thermal ablation. HPV16 is the most persistent and carcinogenic type.
