Are certain cases of colon cancer more aggressive than others? - cancer colon more condition_symptoms

My father died of colon cancer until December 2007, shortly after 9 months. but I read that the survival rate was higher than that. He had surgery, chemotherapy and radiotherapy. I wonder whether some cases can be treated more aggressively and more difficult than others?
