Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This randomized phase II trial is studying green tea extract to see how well it works compared to a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. The use of green tea extract may stop cervical cancer from forming in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia. It is not yet known whether green tea extract is more effective than a placebo in preventing cervical cancer in patients with human papillomavirus and low-grade cervical intraepithelial neoplasia.
