Benign colonic tumors: for example, polyps, benign polyps over three centimeters are relatively large, first of all, you can consider the laparoscopic resection under the electronic enteroscopy and titanium clips for local bleeding points to stop bleeding. Surgical resection is performed if necessary.
Malignant tumors of the colon: malignant lesions of the colon, if the tumor is 3 cm, first need to rule out the existence of local or systemic metastasis, but also need to improve the pathology biopsy under the electronic enteroscopy, ruled out the contraindications to surgery and there is no clear metastasis, you can carry out radical surgical resection treatment. Postoperative radiotherapy or chemotherapy can also be used.
If there are metastases, extended surgery can be considered, or radiotherapy is the mainstay when surgery is not suitable.
