Hi there,
I think if you go to the lung cancer section here, you'll find all kinds of coversations about tarceva. It's been proven to be a wonderful drug, keeping patients stable for sometimes years. Your doctor should have given you information about the drug and it's side effects. My oncologist gave me an entire loose leaf notebook along with some cream. Some of the side effects are diahrea and facial sores resembling pimples. I do think though, if you check out the lung cancer discussions about tarceva and what good results people are having with it, you'll be pleasantly surprised.
I was stage 3a non small cell lung cancer, and I've been cancer free since July 2010. I am so very thankful to God, and I pray your husband recieves excellant results with the tarceva. God Bless the both of you, Byrd
