Mom Diagnosed With Lung Cancer

Hello all,

my mother age 60 has been preliminarily diagnosed with lung cancer, breast cancer, and lymphoma. All of the stages, details, etc are forthecoming and I will share those with you to get better insight, but my main concern right now is the lung cancer. Her left lung was completely full of fluid and had to be drained yesterday at which point it collapsed, her heart sac has fluid around it and her liver was not functioning to it's full capacity. The lymph nodes are visible through the under-arm. She smoked for over 40 years quite the day she was diagnosed last month. Too little too late. I also quit the day she was diagnosed and I have smoked for 22 years. What should I expect given that the cancer is in multiple locations? Her breathing is obviously labored and she has trouble moving around without a wheelchair. The odd part of this is that it has been a very quick decline from a very active 59 year old to a very limited 60 year old. Over the span of 6 months I watched as she rapidly deteriorated to a state where she could not even climb a set of stairs or hold a conversation for too long. I forced her to go to the doctor and my worst fears were realized. She has 3 grandchildren ages 11 months to 10 years old and I have not told them the extent of what we are facing right now because I am not too sure myself. How long does she have? Will she leave the hospital etc... Will her functions improve? I know that I need to wait for the staging but given what I have right now what do you think?

Thanks
