Tell her very simply and directly what's going on, and then immediately tell her that you know it's scary and upsetting news, but that you need her to be there for you. You'll be taking care of your daughter and yourself, and right now what you both need is for those around you to be positive and supportive. Then I'd give her no more than one reminder between now and Thanksgiving (although it's up to you if you want to give any at all) -- if she starts with the pessimism, "Mom, I know you're anxious and upset, but hashing over the worst-case scenarios is too upsetting and makes this a lot harder for me, and I need you to stop." If she still can't stop, cancel the trip for Thanksgiving. You can't be a good support for your daughter if you're too upset about your mother's reaction.
I think you should do whichever you think will be least stressful for you, in terms of going for Thanksgiving or cancelling. But in either case, I think you can say something along these lines above to your mother.
Is it possible that her constant contacting of you by text, Facebook and calls is because she thinks this needs to be checked and she doesn't know you are doing it, because (understandably) you haven't told her because she will make you more anxious with her gloom and doom? In other words, she may be badgering you because she thinks you aren't taking action and she thinks she can get you to do it, but you know that you already are.
If that's so, then would it help to tell her that you've taken your child to the doctor and they're doing tests (so she knows it's being addressed and can stop bugging you on that point), and that while you are waiting to hear back, you need her NOT to be contacting you for updates or questions or speculation? You could tell her something like the above writer suggested, that you understand she's anxious about it but you need her to talk to someone else about that, because it makes it harder for you and you don't need the speculation right now. You could say that when you know something you will let her know, but until then you don't want to talk about it and don't want her to text/FB/call you.
If you think she will ignore that and bother you anyway, then take whatever measures you need to in order to best protect your own peace of mind while you're in this very stressful situation. Whether that's not telling her what's going on until you have results and coming up with a reason for your child's bandage, or cancelling the trip, do what you need to for yourself and your child and your husband.
