This early phase I clinical trial studies the side effects of topical fluorouracil and
imiquimod ointment in treating patients with high-grade cervical intraepithelial neoplasia.
Topical fluorouracil may kill precancerous cells. Imiquimod ointment may stimulate the immune
system. Applying topical fluorouracil and imiquimod ointment may cause fewer side effects and
may be a better way to treat patients with precancerous cervical lesions.
