The surgical approach for colon cancer should be tailored based on the specific circumstances of the patient, involving a rational, comprehensive treatment strategy. The surgical principle is that early-stage cancers should undergo curative resection, while more advanced cancers should be treated with radical surgery or extended radical surgery. Once the treatment plan is determined, the choice of surgical methods should be made comprehensively based on the patient's specific conditions. For example, in the surgery of rectal cancer in the middle and lower segments, it should be considered whether to preserve the anus or perform abdominoperineal resection based on the tumor's biological characteristics, patient's age, overall health, and any concurrent diseases. It is not that there is one fixed type of surgery; the approach should be specifically tailored based on the detailed analysis of the issues at hand.
