Didn't know I was limited space. I had follow-up cat scan in Aug that showed I have three new densities in my same lung. No mets anywhere else. Did a 2nd cat in Sept that showed same so Dr is continueing tarceva. He thinks it will still fight cancer-didn't mention it could mutate. I still feel great but have noticed some shortness of breath. My chin continues to break out & Dr said that is a marker that tarceva is working. Also it works better in non-smokers. I still believe my quality of life is greatly improved on tarceva. Has anyone else had the tumors recur? What did Dr recomend? I have never had a 2nd opinion.
