Hi Theresa,
and welcome to the site. Not many of us have had brachytherapy so I am sure that is bound to help those coming in with that decision.

Most of us have had radiation though so we know what you're going through in that area.

I also opted for nonsurgical treatment and the radiation and chemo combination completely shrunk the tumor to obliteration within the first 3 weeks of treatment. There was no trace of it on the midpoint CT scan. It was a remarkable "before and after" comparison.

I know what you mean about checking your tongue constantly - it's the most logical place for the tonsil cancer to migrate to and they have been watching my tongue closely also. There will be some scar tissue from the radiation that will fool you, as it did me. At over 6 months out I am less worried about it and the doctors feel pretty good about a "complete response" to the treatment. I am not checking my mouth every day anymore. I do stay on top of dental care as I opted to keep ALL of my teeth.

Once again, welcome and I will add you to my prayer list also.
