Anytime we deal with the "unknown", it's very easy to think of the worst that can happen - but even the term "unknown" suggests that it could also mean something good. The good I see here is that you have a team approach which means several doctors get together and decide the best approach for the patient. There have been so many advances that can make a big difference in the getting the best care for your husband. Does your hospital have a website? You can find out lots of stuff there about all the doctors, what their experience is, their research and where they received their education. Which hospital are you with? (In case someone else here has had an experience there)
So have your questions ready (yours and your husband's) and bring a notepad to write down what the oncology team has to tell you. . . . if you don't understand something, be sure and say so or ask why. It's only 10 days away so try to keep busy. And find some moments to smile with your husband.
