Hello Terri, Welcome! Your father has a difficult road in front of him. It sounds like he doesn't want to be a burden for you, but in fact his situation is a burden anyway. Try to explain to him that you need to know and that he needs you to know. I realize that may be difficult but it is important that you know.

I also want to advise you in a practical sense that he needs to tell you what his financial situation is and get a will and a medical care directive in order. YES he might survive this and I don't want you to freak out. You need to know so that your grandmother is well cared for. If your father goes through radiation treatments he will probably not be able to care for your grandmother for a while. The treatments are really going to set him back. We can answer questions as they come up but you need to connect with him in a really close way now.

Feel free to ask questions here all you want.

Take care
