Grandma appears to have improved considerably!  Received the following message from my mother this morning from Taiwan:

"We just came back from the hospital, Grandma just came out of operation room still sleeping. the operation was very smooth. She has a chance to come home, my brothers are preparing for her home coming some day. She stopped bleeding after the tumor removed and 6 pts of blood transfused. The only trouble with her now is breathing, she has to be trained in hospital until she can breath by herself then she can come home."

Looks like Grandma plans to stick around for a while!  Good for her.
