I thank you both for your above replies. We will be researching further and are in contact with two other docs out of state, one in San Francisco and one at the Cleveland Clinic. Perhaps we should consider treatment at a comprehensive cancer center, as you mentioned Tammy.
I am a nurse, but I'm a labor and delivery nurse, and this whole thing is far out of my area (I hesitated to even include my occupation on my profile bc it certainly does not apply here, as far as I'm concerned)
Vanpaddler, I'm glad your treatment was successful and that you were left with minimal side effects. I understand radiotherapy varies a lot depending on how it's administered and by whom. This only complicates the issue further for us, and we're still trying to understand it all.
Again, thanks to you both. I'll be reading more on here, and perhaps posting from time to time.
