@catdoris I am only sharing my own experience. I have no symptoms either. I went to the ER because I hurt my back and they took chest x-rays and that’s where they found the tumors. I did a biopsy of my lungs but the idiot collapse my lungs and I was really struggling for a while and then they found out it was Cancer. It took quite a while. I started in May and I didn’t get my diagnosis until June and then I had surgery in September because it was doubling in size every month I got my right upper and lower lobes removed and some lymph nodes have test size and I went through Kimo and now Tagrisso
