My sister first had eye cancer, then lung cancer, both are gone, then she had cancer somewhere else Cant think right now. That too was treated and gone. Her kidneys are functioning at 40% due to chemo. Yesterday she was diagnosed with cancer in her spinal fluid, test could not find any in the brain but we are all pretty sure they just haven t found it there yet. She had radiation today on her spine and steroid treatment for the swelling of the tumors on her spine. At this stage what is her life expectancy?
