Yes, you can live quite a normal life with one lung...I had a lobe removed in Sept and feel quite fine...no breathing difficulties etc...so I would think that once chemo and radiation have done their job I would definitly not hesitate to have a part or the whole lung removed...whatever is deemed necessary...I have heard of people living with 1/2 of a lung...of course with oxygen...but still...if its going to save your life...Good luck and God Speed.
