Thanks Everyone for all of your advice and thoughts. It helps to know I'm not alone in being terrifed that we will not make the right treatment choice and regret it forever. I feel like given the info we got from both the Dr and through extensive research we made the best decision for us. I'm on my knees praying that this was the right one and I get many years left with my Dad.

That being said, he began his first cisplatin and rads trmt today. So incredibly hard to watch him go through this. I have cried I think as much as I can cry. But I am hopeful that he can withstand the side effects and we can just get through each day.The have already given him a slew of meds and the cisplatin hasn't even begun infusing yet. So I hope that all of these will help him. I am terrified and sad, but I have nothing else to do but wait and watch. Any advice on what I can do to help him is greatly appreciated. Keep your fingers crossed for us!
