What are the treatment options for colorectal cancer?

The type of treatment a patient receives is largely determined by the severity of the condition. Some patients with colorectal cancer notice improvements with one method of treatment, while others are treated with a combination. Treatment options include: 
 
Surgery
  • Polypectomy is the removal of polyps during a colonoscopy. A colonoscope (a long tube with a camera on the end) allows the doctor to inspect the inner lining of the large intestine. A tiny, scissor-like tool or wire loop is used to remove the polyps. 
  • Colectomy, also known as hemicolectomy or partial colectomy, is a procedure to remove areas of the colon invaded by the cancer, along with some healthy surrounding tissue.
  • Endoscopic mucosal resection (EMR) is the removal of polyps on the surface of the colon using a needle that is placed in the colon wall, and then injected with saline to make a bubble under the growth. The lesion is then removed using suction. 
  • Endoluminal stent placement uses an endoscope to place expanding metal stents to help relieve a bowel obstruction.
  • Permanent or temporary colostomy is surgery to create a way for waste to leave your body. An opening in the wall of your abdomen is created for the elimination of body waste into a special bag. 
 
 
Chemotherapy
Chemotherapy refers to the use of chemical agents whose main effect is either to kill or slow the reproduction of rapidly multiplying cancer cells. This results in tumor shrinkage or cancer cell death. Drugs can be delivered through a vein in your arm (intravenously), or they can be taken orally
 
 
Radiation Therapy
Radiation therapy damages the DNA of cancer cells by the use of high-energy X-rays or other types of radiation. It may be an alternative to surgery or used in combination with surgery and/or chemotherapy. 
 
 
Targeted drug therapy
Targeted drug therapy works by targeting specific abnormalities in cancer cells. This form of treatment is often combined with chemotherapy drugs.
