Fourteen women with a biopsy-confirmed CIN3 diagnosis will be enrolled. The participants will receive 500mg of curcumin orally twice daily for 12 weeks. Colposcopies will be performed at the participants' baseline, 6 week, and 12 week visits. Two biopsies will be performed at the baseline and 12 week visit, and if there is suspicion for cancer formation or invasion, at the 6-week visit. One sample will be used for histologic examination, while the other sample will be used for p65 assays. Based on the biopsy, if cancer is present, then the patient will be referred to gynecologic oncology for further care and the trial will be terminated. At the end of the 12 week period, if CIN3 persists, Loop electrosurgical excision procedure (LEEP) or Cold knife conisation (CKC) will be performed to remove the dysplastic cells as this is considered standard of care.
