What Is The Prognosis For Colon Cancer?

Every person responds to treatment differently but, the extent of disease at the time of diagnosis as well as its rate depends on how the patient responds to treatment. Several factors determine how fast a person responds to treatment and how well a person will do after treatment of colon cancer.

The factors that influence colon cancer prognosis are:

  • Stage: Firstly, the stage refers to how far the colon cancer has metastasized. It is the most critical factor. Research done by the American Cancer Society states that if the cancer has not spread to the lymph nodes or any other distant body organs, it tends to have a better outcome upon treatment than if the cancer has metastasized.
  • The number of lymph glands involved: The lymphatic system is a part of the circulatory system which comprises of the extensive network of lymph vessels and lymph nodes. Furthermore, it aids in the coordination of the body’s immune system to protect the body from foreign substances. The higher the number of lymph nodes contains cancer, the greater the chances of cancer recurring. Therefore, chemotherapy should be done in this case.
  • Colon blockage: When the cancerous cells grow through the walls of the colon, they may cause holes in the bowel or obstruction of the colon. This can affect how well you respond to treatment.
  • Spread of cancer to other organs of the body: Lastly, if the colon cancer has advanced, it tends to spread to other body organs like the lungs. This will lead to radiation and additional chemotherapy which will help in reducing the rate at which cancer spread.

Other Factors That Affect Colon Cancer Prognosis

  • One’s general health: The healthier one is at the time of diagnosis, the faster one responds to treatment and the side effects of the treatment.
  • The quality of the surgery offered: This is considered to be very important in a case where it is administered on rectal cancers. This is because it may turn out to be a complicated surgery.
  • The presence of carcinoembryonic antigen: Carcinoembryonic antigen (CEA) is a protein molecule that is present in the blood. This molecule increase is the colon cancer travels to the blood, and this may affect the rate at which you respond to treatment.

What Are Survival Rates Of Colon Cancer?

Many colon cancer statistics involves a five-year survival rate. This is according to research by Surveillance, Epidemiology and End Results (SEER) Program. The following explains the information in detail:

  • Localized: If cancer has not metastasized, it usually has a survival rate of five years of 90.1%
  • Distant: If cancer has metastasized to other organs, the five-year survival rate is 13.5%
  • Regional: When cancer has spread to the nearby lymph nodes, the five-year survival rate is at 71.2.
  • Unknown stage: This is where the person diagnosed with colon cancer defaults treatment and further testing. The survival rate is therefore unclear, and the five-year survival rate is 35.5%.
