Patients with colon cancer and colorectal cancer may have hemicolectomy. Surgery to remove part of the colon or large intestine is called hemicolectomy or sigmoid colectomy. Depending on where the cancer is located will determine which side of the colon is removed. Colectomy. The primary treatment for colon cancer is surgery. The part of the large bowel with cancer is removed, along with surrounding lymph nodes. Removal of the colon is called a colectomy. The remaining bowel is then joined together.
