Cancer of the colon is a highly treatable and often curable disease when localized to the bowel. Surgery is the primary form of treatment and results in cure in approximately 50% of the patients. Recurrence following surgery is a major problem and is often the ultimate cause of death.Incidence and Mortality
Note: Estimated new cases and deaths from colon cancer in the United States in 2014:
- New cases: 96,830 (colon cancer only).
- Deaths: 50,310 (colon and rectal cancers combined).
The prognosis of patients with colon cancer is clearly related to the following:
- The degree of penetration of the tumor through the bowel wall.
- The presence or absence of nodal involvement.
- The presence or absence of distant metastases.
