What factors affect prognosis with colon cancer?

Pathology stage: The cell type, dna type (k-ras mutation, etc.), stage of the cancer depending on how deep it may invade, whether the cancer spread to lymph nodes or other organs; these are some of the evaluations performed after the cancer is surgically removed. Overall health and age have some affect, but not as much.

Staging & treat soon: Staging addresses prognosis--based on tumor depth of local invasion through colon & spread of tumor (metastasis) to sites distant from primary mass. Histology (microscopic typing), genetic factors (polyposis syndromes), age of onset, co-morbidities, completeness of removal, & environmental factors (for example Aspirin increase survivability) all play roles. Early detection & removal is key here.
