Tubulointerstitial adenoma is usually a benign tumor, but it has a certain tendency to become cancerous. Early detection can be cured by surgical excision, and its development time to cancer is related to the shape and size of the tumor and the treatment effect. Tubulointerstitial adenoma grows slowly and is clinically manifested as a painless mass. If the diameter of tubular adenoma is <1cm, it can be surgically excised and can achieve clinical cure after surgery. If the tumor is >1 cm, it is prone to malignant transformation and requires timely pathological examination to clarify the specific pathological grade, such as low grade, intermediate grade or high grade intraepithelial neoplasia. After the pathological examination results are clarified, patients should undergo thorough treatment as soon as possible to prevent the development of cancer, which can be done by surgical resection or interventional treatment. Patients are advised to take timely treatment such as surgery after the discovery of tubular adenoma, which can stop its developmental changes to a certain extent. In addition, patients should also pay more attention to rest and develop a good life rhythm in general.
