Staging is a method of evaluating the progress of colon cancer in a pateint.
That is, it looks at the colon cancer (tumor) and the extent to which the cancer has spread to otehr parts of the body. Once doctors know how far along the colon cancer is, they can decide on the best course of treatment.Today, the most common used sysetm for the staging of colon cancer is the American Joint Committee on Cancer's (AJCC) TNM staging system. This staging system places patients into one of four stages (Stage I, Stage II, Stage III and Stage IV).American Joint Comimttee on Cancer (AJCC) Staging SystemStage 0 Colon CancerIn Stage 0, the colon cancer is found in the innermost lining of the colon only. Stage 0 colorectal cancer is also called carcnioma in situ.Stage I Colon CancerIn Stage I, the colon cancer has begun to spread, but is still in the inner lining of the colon or rectum.

Another name for Stage III colroectal cancer or Duke C.Stage IV Colon CancerIn Stage IV, the colon cancer has been carried through the lymph system to distant parts of the body. This is known as metastasis. The most likely organs to experience metastasis from colroectal cancer are the lungs and liver.
