@shiwlika Welcome to connect. I am colon cancer survivor. It is very scary at first when you are diagnosed. However, we are lucky to be born at a time where they have made tremendous progress with treating colon cancers.
My colon cancer surgery was done at Mayo. They check my CEA levels every six months. I believe they do that for 5 yrs post op.
I had a colonoscopy at 6 months post op. Then at 1 year post op. Now I am on a schedule of every 3 years for a colonoscopy.
Hope that helps? I did not have adjuvant chemotherapy so I cannot help answer that. .
I wish you the best
Jackie
