I am wondering how many of those with lung cancer, started out with a non-calcified nodule of 6mm or slightly larger? My husband has one this size when I requested a CT due to his shortness of breath. The Dr. didn't feel it was necessary, then they found the small nodule. He was to go back in six months and after demanding he call the doctor and get one set up, it will be nine months since his last scan. His shortness of breath scares me. He needs to lose about 40 pounds and feels that is the reason he has the problems. While I see that as an issue as well, I also see breathing problems. Any input would be appreciated. Always the worrier.
