I am a month past my ct scan showing a mass on my left lung. I too had terrible anxiety while waiting for pet scan mri and biopsy results. My way of coping has been to lean on family and my faith. Although the results confirmed cancer they also showed hope for a treatable type with no surgery or chemo. The last step is where I am now and after 19 days I learned that the lab didn't have enough tissue, so I am back to waiting for next steps. It's tough and I can't give any great advise accept that we are being treated by the best team of doctors in the country and I keep reminding myself that the wait will be worth it when they know the exact DNA to treat.
