In some cases, enhancement CT can help detect bowel cancer, but it cannot fully characterize it. Because after suffering from bowel cancer, especially in the middle and advanced stages, you can see obvious masses in the intestine, and then enhanced CT will show a different shape from normal. However, some benign tumors or junctional tumors are basically close to intestinal cancer, so the most accurate way to examine intestinal cancer is to do colonoscopy and take a small part of tissues for pathological biopsy. If tumor cells are found in the tissues, the diagnosis can be confirmed. After the discovery of bowel cancer, it is necessary to actively improve relevant examinations, perform radical resection of tumor, and then cooperate with lymph node dissection, and later give chemotherapy, targeted drug therapy and Chinese medicine treatment, etc., the disease may be cured. Even if the disease is severe, it can prolong the life of patients and improve the quality of survival.
