@amareese I have EGFR mutated adenocarcinoma stage 1B. I have ~30 pulmonary nodules and 3 primary tumors (each has a different activating mutation). I have the genetic T790M mutation that makes it easy to develop lung cancer, similar to the BRCA mutation with breast cancer. I'm on Tagrisso, which is a targeted therapy that blocks T790M, and 2 of the 3 primary tumors have resolved. in your initial post did you mean that your EGFR tumor doesn't have any targetable mutations?
