I have COPD and was recently hospitalized. I was diagnosed with exasperation from bronchitis. From chest x-ray they thought I might have small blood clot on lung and did a CT scan. It turned out to be an nodule. They did a comparison to a 2014 CT scan I had and noticed the nodule was enlarged so radiologist wants to repeat in 2-3 months. I didn't think much about it cause I was just happy to breathe and get home. But now starting to worrying and wonder if anyone else has had this. Could it be caused by a infection? They scheduled my appointment 3 months out but wondering if I should go in two? We have had so much cancer in our family and it is always in the back of my mind. Thanks for your help!
