I done the same thing my last diagnoses for Head & Neck cancer, I found all sorts of things that said I should be dead, or would be soon. all gloom and doom stuff. I went to the first meeting with doc and asked all those questions, He says, "you've been on the internet, haven't you"? Don't put too much stock into what you read about numbers, percentages of who will make it, reoccurence, etc. Every case is different, some worse than others, some far better than others, you are you. Even if the numbers say 90% won't make it, OK, somebody has to be in tha 10%, might as well be ME.
Ask particular questions about YOU. What is the Plan. When do we start. How long will it take. What drugs will I get. What are the side effects. What should you do if you see, feel, or have something that's wrong. Who should you call in the middle of the night if you need to. Will you have radiation. Write the questions down, have them ready when you go to the doc. I always forget what I wanted to asks.
Best of luck to you, you will be on the other side of this before you know it!!
