Surgery: If the cancer is localized in the polyp, a simple colonoscopy is the only treatment required to remove it. In a laparoscopy, a thin, lighted tube mounted with a tiny video camera is inserted into an incision in the abdominal wall. Guided by the image generated on the screen, the operation is performed by special instruments.
Chemotherapy: Some colon cancer patients develop abnormal microscopic that escape detection and metastasize to other parts of the body. In such cases secondary chemotherapy is given after surgery.
Other Treatments: For metastatic colon cancer, other procedures may be employed like radiation and immunotherapy, etc. Surgery may also be performed on other areas where the cancer has spread.
