Many people with colon cancer experience no symptoms in the early stages of the disease. When symptoms appear, they will likely vary depending on the cancer size and location in your large intestines.
Terms describing the orders of treatment:
Note:- Colon cancer is a serious disease that can be treated. Not every person will receive every type of treatment listed. They are several terms used to describe the type of treatment to be given ex:- some people receive chemotherapy after surgery. In this case surgery is the primary treatment and chemotherapy is an adjuvant treatment.
If the cancer has grown beyond the polyps a colectomy is done to remove that part of the colon with cancer. There are a few steps to prepare for surgery. In this case you need to stop taking medication to reduce the risk of severe bleeding. Eating less changing to liquid diet or using animas, laxatives will empty the colon for surgery. A colectomy is done with either an open or a laparoscopic method. The Laparoscopic approach removes tissue through a small incision with a laparoscope.
The surgery to remove lymph nodes is called lypmphectomy. It is often done during a colectomy. A minimum of 12 nearby lymph nodes should be removed and tested. All abnormal looking nodes shall be removed too.
The treatment uses high energy beams to kill cancer cells. It is not often used to treat colon cancer. External radiotherapy delivers a beam of radiation from a machine outside the body. Internal radiotherapy places a radioactive object near or inside the body.
Colon cancer is able to spread beyond the colon to other parts of the body. Doctors use drugs to treat cancer cells that have spread through the body. The treatment is called systematic therapy.
Chemotherapy and targeted therapy are systematic therapies for colon cancer. Most of these drugs are liquids that are injected in the vein. Others are a pill that is swallowed. The drugs travel in the blood to all parts of the body where they attack cancer cells.
