Indications and contraindications for surgery in colon cancer

For colon cancer, surgery is still the main treatment method. The purpose of surgery is to remove lesions, reduce tumor burden, alleviate symptoms, obtain tissue specimens to obtain biological information of the tumor, estimate prognosis, and guide comprehensive treatment.

1. Indications for surgery

1. Tumor factors

2. Host factors

The patient is in good general condition, and the functions of important organs such as heart, lung, liver, and kidney can withstand the impact of surgery and anesthesia. The patient and his family members approve of surgical treatment.
