Hello everyone,
Thank you all for your responses. All of your responses have given me so much to think about.
I have been so overwhelmed these past few days about what is the best treatment for my mother.

I don't know all of your ages, but my mother is 70yrs old. We have to take into consideration her age and what radiation can do to someone of that age.
She is getting treatment at one of the CCC centers in our town. Getting treatment at the actual CCC is out of the question. The distance is to far for her to travel daily for radiation treatments.
I had some more questions for the RO so we called him today and we went to see him again to discuss my mother's treatment. We have met with him 3 times now. We had no problem getting in to see him. I am very confident that he is a good RO. He actually worked at the main CCC a few years ago. He specializes in head/neck cancer.
We talked again about the IMRT treatment verses the conventional radiation. We discussed the benefits and risks just as Gary suggested.
Again he said she is a stage1-2. No lymph node involvement and clean margins with surgery. 1/2 of tongue removed.
He was only considering the IMRT if he was going to radiated both sides. He spoke with her ENT dr. and they both decided that she needs only the right side treated. He said IMRT is not for everyone. He felt if he was to do the IMRT that my mother would not be able to handle the full treatment and if he had to stop treatment because of the side effects than that would be no benefit to her. One of the main factors was her age and the quality of life she would have. He did not directly say that but that was what I felt he was expressing. If she did have lymph node involvement than the IMRT would be the treatment planned.
She had SCC back in 1986 and 1988 and had been fine until now. Each of the 3 times this has occured the patho report stated moderately well differentiated SCC. Which is the better one to have he said. The gap from 1986 and 1988 until now is about 17 years. When she had it in 1986 and 1988 she just had surgery. Now she is having radiation. Hopefully this will take care of it.
At this point they got all the cancer out with surgery. The microscopic cell are what we are dealing with now.

So we are set up to begin radiation this Thursday with the dry run on wednesday.
Deciding on the treatment process is very stressful and overwhelming. I am beginning to see what all of you have gone through.
I commend you all for the strength and courage that you all have shown. That is where I have gained some of my strength through all of your support and kind words. I thank you all very much.
Nelie I do hope your swallowing issues gets resolved. I have been thinking a lot about you lately.
I wish you all the best.
I will keep you undated as our journey begins. Anymore thoughts or suggestions are always appreciated.
My thoughts and prayers are with you all.
