What should be done if a biopsy of a colorectal polyp shows cancerous changes?

When biopsy results of colorectal polyps show malignancy, prompt and aggressive treatment measures should be initiated immediately. Doctors may recommend colectomy or proctectomy to remove the cancerous tissue along with potentially affected lymph nodes, in order to prevent further spread of cancer cells. Adjuvant therapies such as chemotherapy and targeted therapy may also be used to kill or inhibit the growth of cancer cells. After surgery and treatment, patients require close monitoring of vital signs and wound healing, and should follow their doctor's recommendations for regular follow-up examinations to promptly detect and manage any recurrence or newly developed polyps. Through comprehensive treatment and postoperative surveillance, the progression of malignant transformation in colorectal polyps can be effectively controlled, improving both survival rates and quality of life. For patients with malignant polyps identified on biopsy, early medical intervention and adherence to professional medical advice are crucial.
