My wee mum who is 66 has been diagnosed with primary lung cancer which has spread to lung,liver and brain she is on an anti seizure tablet and dexamethasone I am speaking to the medics in her behalf because she is terrified the doctor told me last week that she had 6 to 8 weeks without treatment of 6 to 9 months with treatment of course it depends if she is strong enough  I told a nurse on Monday that we would like to speak to the doctor about treatment and she said she would message him but we have heard nothing since I'm terrified I keep imagining a clock ticking down one now mum has a terribly sore lower back  this started after she had a liver biopsy and had to lay flat for 7 hours afterwards she is eating and drinking just like normal but the back is really getting her down and nothing seems to help does anyone know if chemo does extend things or are we just clutching at straws TIA.
