I'm sorry that you have to wait a little longer before your plan of action is in place. It's tough to have a partial answer and still have to wait for action. Continued prayers for you both.
Waiting can be such a breeding ground for worry, can't it? Lifting prayers for peace for you both in these times of uncertainty and wondering and waiting. And praying even more for a positive prognosis and a return to health when the specifics come to you.
Cancer is curable these days. I am proof of that. My Mom had three kinds of cancer and she lived to age 90. It wasn't cancer which ended her life. I have another friend who has lymphoma and he is doing well five years later. Hang in there and try to have hope, as scary as it is.
