Larry,
Sorry to hear about your sister's condition and the stress that it brings to you and everyone else that loves her and cares about her.
I am glad to hear that they found it and are acting quickly to remove it.
Surround her with love, laughter and positive, healing thoughts and energy. If you can't think of anything to cheer her, spring the happy banana
on her!
If she seems to be struggling with it, reach for her hand.
