Hi, Doc. I am concerned about lung cancer. I have so many of the symptons....5 incidents of pneumonia in 1 year, even after a pneumonia shot. The last one was microplasmic double pneumonia and I had to be isolated in the hospital. The ex-ray always shows pneumonia but cancer has never been raised. I also have a bone dry throat, hoarseness for several years and COPD. My father had lung cancer. If an X-ray doesn t show anything, would I still be able to get a bronchioscopy and is that ever the way it is diagnosed.
