a family member has metastised breast cancer to the R lung, liver and brain. While the liver and brain are under control for the moment, the lung seems to be spreading quickly. The doctors are removing about 1 litre of fluid every 5 days, and she is on 8-12 L of O2. A cat scan has revealed that the tumor has doubled in 2 wks, and the left lung is showing some shadows. She is scheduled for pic line tomorrow. How long do you think she has?
