Treatment options for Colorectal Cancer :
Standard options for colorectal cancer treatment include:
Partial Colectomy for Colorectal Cancer)
Partial Colectomy (also called partial bowel resection)—The tumor and normal tissue on either side of the diseased area in the colon are removed. The surgeon then reconnects the healthy colon. Sometimes the physician may have to create a temporary colostomy, or an opening for solid waste from the bowel to a special bag a patient wears outside the body, until the healthy tissue has healed. At times, the colostomy is permanent.
Laparoscopic Surgery or Keyhole Surgery for Colorectal Cancer —
Small tube-like instruments and an extremely small camera are inserted into the abdomen through incisions made in the abdominal wall. The surgeon sees what the camera sees on a television-type screen and can cut out a large section of the bowel and adjacent tissue, called the mesentery.
Radiation Therapy for Ccolorectal Cancer -
High-energy radiation is used to kill cancer cells. Radiation may be used in conjunction with surgery as definitive therapy, or may be used to reduce, or palliate, the symptoms of colorectal cancer such as pain, bleeding, or blockage. Radiation therapy is usually delivered as external-beam radiation. Radiation comes from outside the patient’s body and is directed onto the cancer and surrounding tissues.
Chemotherapy for Ccolorectal Cancer —
Drugs are given intravenously or orally to kill cancer cells. Chemotherapy is often given to decrease the chance of the tumor returning elsewhere in the body. Like radiation therapy, chemotherapy can ease disease symptoms and increase length of survival for patients with tumors that have spread
