If colon cancer can be treated surgically, generally, the outcomes might be quite good. It often applies to cancer in relatively early stages, with potentials to survive for over three years, five years, or even longer. Of course, there are cases of colon cancer that are discovered in later stages, where complete surgical removal is not possible, and only palliative stoma surgery can be performed. In such situations, the survival time might be within three to five years, but the exact life expectancy cannot be fully determined. Each individual's condition is different, and treatment must be adapted accordingly. Typically after surgery, treatments like chemotherapy, radiation therapy, and targeted therapy might be used in combination to prolong survival.
