Heather,
Welcome to our club and sorry you need to be here. As you've already heard there are more treatments added for Lung Cancer in the past 5 years than in the previous 20 so your husband can have a good chance of overcoming this disease. Surely you'll be hearing from others soon with even longer periods of NED (No Evidence of Disease) since their diagnosis, but in May of this year I will be two years out from my LC (lung cancer) diagnosis and surgery. So, stay strong and let us help you by sharing our experiences.
Lou
