Hi Kathy,
I know that this is scary. Breathe. Take it one day at a time.

My Kris also had a BOT tumour treated with rads and chemo.
At his routine checkup and scope the ENT saw a new ulcer in the same place as his original tumour.
Kris then had this new ulcer biopsied under a general anaethetic. This caused him absolutely no problems. No pain, no bleeding. A biopsy only removes a small portion, it does not cut hugely into the tongue or carve it up. It is a simple procedure .
Kris also had a CT which showed a small local reoccurence at the same site of the original tumour. This together with the pathology of the biopsy was what was needed to decide the next option for treatment.

As nothing has been seen on Kevins scopes maybe thats why they want to wait until after the MRI. Should this show just healing inflammatory tissue, then a biopsy may not be needed.

All my fingers toes and legs crossed for you both.
Hugs to you,
Tammy
