How is sigmoid colon cancer treated?

Sigmoid cancer is treated by surgery to remove the lesion and its adjacent tissues. After surgery, doctors will also give relevant adjuvant therapy according to the cancer stage, including chemotherapy, molecular targeted therapy, immunotherapy, etc. For patients with early disease, after systematic treatment, clinical cure can be achieved. However, if the disease is detected later, the prognosis is usually worse. Therefore, once diagnosed with sigmoid colon cancer, patients should go to the hospital in time for treatment under the guidance and advice of doctors, and regular reexamination should be carried out during treatment to prevent tumor recurrence.
