Should I do chemo after surgery?

I had colon cancer and I did the full surgery for them to remove the mass the surgeon said he didn’t think I needed chemo but the oncologist said she wanted to do chemo because of my age.

I had stage 1 they told me I didn't have to do chemo or other meds because it was removed by recesction. The only one that can make the final decision really is you. I was offered by my surgeon to do the full surgery instead of just the sigmoidoscopy resection (which is where they go in by ultrasound and a scope and remove it) but they later came back and said that they couldn't encourage me to get the surgery because it was no need. But what is the reasoning for your surgeon to recommend chemo?

My cancer was stage 2 I had a mass but he also removed the lymph nodes and the were negative.

What stage was your cancer? Are any lymph nodes involved? Did you have a mass?
