My mother was recently diagnosed with brain cancer, which resulted from her also having lung cancer. The doctors will not tell us what stage or how long her life expectancy is either. She was told that she can't have chemo and radiation at the same time, is this true? I'm concerned because while she's getting radiation for her brain cancer the other is just going to spread like wildfire since she can't have the chemo...it's such a mess. Any advice would be greatly appreciated.
