CT examination can help us clarify the invasion of the intestinal wall by lesions. It is a very critical examination item for the staging and efficacy evaluation of colon cancer. However, it cannot directly diagnose colon cancer because it examines hollow organs such as the stomach and intestines. The sensitivity is low, so CT examination has limitations in the diagnosis of colon cancer. Only when the tumor grows and causes the intestinal wall to thicken, CT may be able to indicate colon cancer, but the diagnosis requires colonoscopy and cancer cell specimens. Make a diagnosis.
