Based on our research and asking around, one of the best lung cancer especialists is Karen Reckamp, we have taken our mom to her for consultation on a number of occasions, she is good and has a number of clinical trials going.
There is another guy that is supposed to be very good his name is Robert Figlin, however, we have not met him.
Keep in mind that these guys are all good at COH. the two names are base on the research I did.
Best of luck.
