My Rad Dr told me that mine was completely curable. On my way to see him for the first time I saw a billboard that said Trust God and before thinking about it I shouted I do. Well I put my trust in my Dr as well and I still don't understand what stage I had but I had no surgeries and no Chemo. 33 radiation treatments and he said it was gone. Now as with the rest of us we have to watch for it but tell you and your dad to read everything and ASK questions about everything. Write them down so you won't forget. My sister is a RN and a patient advocate so when I didn't understand something I would hav eher talk to the Dr and she would explain it to me in my terms. Keeps positive thoughts about you and your dad the same he WILL be ok. Good luck to you and your dad. I will be watching and praying for you as well. And as everyone will tell you take a deep breath then get busy.
