Rectal low-grade intraepithelial neoplasia cannot be cured by taking traditional Chinese medicine, and this kind of lesion can be cured mainly by surgical resection, and it is generally recommended to monitor the changes of the condition with regular follow-ups after the surgery, so as to detect recurrence and give timely treatment. Low-grade intraepithelial neoplasia of the rectum is a benign lesion, but there is a certain risk of cancer, which is a precancerous lesion. The exact cause of this lesion is not known, and if left untreated, it is likely to develop into rectal cancer in a few years. The main treatment for low-grade intraepithelial neoplasia of the rectum is complete surgical resection of the diseased area with no other postoperative treatment. However, since there is a certain recurrence rate after surgery, regular follow-up is required, and colonoscopy is generally recommended every six months or a year.
