Thanks so much for your response and sharing your story. I see now that cancer is a long journey.

Husband too was cancer free after lobectomy - 0% ctDNA and doing immunology just for “insurance”. . So we were surprised with latest PetScan showing SUV 4.3 on lung. He does not have mutation. APRN said probably CT next, then probably more chemo and/or radiation. We meet with oncologist tomorrow to solidify next steps,
