I was diagnosed with COPD about a year ago. I was told that the emphysema is not that bad and I rarely have a cough. I am usually the last one to get sick, if I do at all. I was told about two weeks ago that I have a 7mm nodule on my lower right lung and a couple of 3mm ones as well. The Dr. told me that I shouldn't be worried but all I do is think about it. I go back in 4 months for another scan. Does anyone know much about nodules on your lungs?
