Bet I know what your going through my mother was diagnosed with Lung Cancer 3 years ago , she had no symptoms the hospital picked it up when mam had a x ray for something else , We were devastated , Mam had Radiotherapy they didn't want to operate because of her age , My mother gave up smoking 28 years ago so it was a shock , Its 3 years on now and she's doing fine she has check ups every 6 months so far there is no trace, So Bet don't give up there is hope please keep us informed , If you need help The Roy Castle Website are brilliant or you can keep in touch with me , take care
