we found out last week that dad had stage 4 lung cancer which has spread to his brain, (massive shock). We lost mum 16 months ago, she had a massive stroke & eventually had vascular dementia- dad nursed mum for 12+ years & this has come as such a shock. We are struggling as a family to come to terms with the prognosis which means the time we have left is pretty short-I am distraught & shocked at how agressive this cancer is & feel so sad for my dad
