Choriocapillary tubular adenomas are usually not cancerous 2 years after removal. Choriocapillary tubular adenoma, also known as mixed adenoma or papillary adenoma, is a pathological type of colorectal polyp with tubular and choriocapillary structure, which is a benign lesion but has the possibility of malignant transformation if not removed early by surgery. The disease may be related to dietary impurity, smoking and drinking and other stimuli, and is prone to abdominal pain, diarrhea, blood in stool and other symptoms. If this kind of adenoma is found, it should be surgically removed as early as possible. If it does not recur 2 years after surgical removal, the chance of cancerous transformation is generally very low. Patients with choriocapillaris adenoma should go to the hospital in time, complete the relevant examination under the guidance of the doctor, and follow the doctor’s instructions for timely treatment.
