Hello John, I write this to calm your nerves about the balloon.
It has been my policy to be non confrontational and to never recommend a treatment.
I chose and experienced Image Guided IMRT with Balloon.
I probably researched the balloon more than anything else since I hated the idea so much. I assure you, it IS best practice. It's also tolerable. Check out the Brotherhood of the Balloon.
I expect that my buddy pcdave will have several paragraphs of carefully done wordcraft to counter what I have said. As always, I welcome his opinion and care.
