Good surgeon, good staff w/some limits, tests and scans scheduled, still some serious pain meanwhile, goes unattended.

Dr. Flermoen is amazing. And his follow up care was very much appreciated.

Still not clear to me what if any options or alternatives exist to the recommendations which seemed to be a "one size fits all" approach. When a CT scan shows no evidence of any malignancy outside of the polyp removed, and surgery excises surrounding organic tissue, is chemo really necessary or just advised as precaution? As a diabetic how much risk is there to having your immune system further compromised?

I received well informed information on my care and treatment. I'm very comfortable & would recommend the doctor to anyone that needs care.
