So sorry to hear this, lmd. I was diagnosed with Stage 1b EGFR in late Feb. had lung surgery in March followed by 4 chemo treatments. Have been taking Tagrisso for not quite 2 months with my first scan scheduled for early Oct. I’m sure you are frightened, but there is such hope for lung cancer these days. I personally know 2 people who have had recurrences and are thriving 15 years after first diagnosis. Stay strong. The community is with you.
