Thank you so much for your replies which are reassuring. Yes, I agree we should get a second opinion and Geoffrey's surgeon did recommend this as he does not appear to have a lot of faith in the present oncologist either. However, when the surgeon phoned Geoffrey last week and suggested this he, Geoffrey, said no he would rather stick with the present one. So I have to go with what he says.
By the way, I am in the U.K. but have not been able to find a simple website over here. Was so pleased to find this one and read the success stories, particularly in relation to Tarceva, which has been available in the States for much longer than U.K. My husband is having is treatment privately so was lucky to get Tarceva as it is not available to everyone here yet.
