I'm hoping that someone can answer a very important question for me tonight. My mother had liposarcoma cancer removed from her back about 8 months ago and the cancer spreaded into her lungs. The Doctor said she could expect to live 5 months to a year. She is having terrible pain in her left breast tonight. So bad that it's taking her breath when she tries to talk. She said it feels like her breast is falling off or something. The doctor said she has fluid in her back still where the cancer was removed and he also said that she has a touch of pneumonia. Could this be the cancer spreading into her back or could this be the fluid moving around. Maybe the pneumonia has something to do with it as well Please write if you have any suggestions. Thanks!
