Does stage 4 colon cancer spread ?

Stage 4 colon cancer is a disease that has already spread to another site in the body, notes the Cancer Treatment Centers of America. It is the most advanced stage of the disease.

Clinicians who diagnose and treat cancer use a staging system to classify the progression of the disease, explains the Cancer Treatment Centers of America. These stages are numbered 0 through 4. Stage 4 is the most advanced stage, meaning that the cancer has spread to another organ in the body. Within stage 4, there are further classifications used to describe the disease's progress. These classifications involve tumor size, the number of organs to which the cancer has spread, and whether or not lymph nodes are involved.
