mom having lung surgery any advice?

I know this has nothing to do with gastric bypass but my mom has had pneumonia since December. They are going in and doing surgery on her they said her lungs have like leather in there and they have to scrape it out and get the infection out. She had breast cancer 5 years ago and has beat it. They took out 6 cups of fluid on her 2 months ago so none of the antibiotics are working. They have to break her ribs to get into her lungs. She has lost 50 lbs in the last 2 months so I will be going home to help out. I feel like there is more going on than she is telling me I almost wonder if she has lung cancer and don't want to tell me. If anyone knows of anything let me know if this sounds right. The surgery will take 9 hours to do so its very serious. I don't want to lose her but her best friend wrote me and told me not to be shocked when I see her. She lives in North Carolina and I live in Washington state so I haven't seen her for a while. Thanks for the information.

I am not familiar with this situation, but I wanted to say that I will pray for your travels, and for your mom, that they get everything, and that she recovers quickly.. God BLess.. Tanya
