I just have a question about how they do lung biopsies? A PET/CT scan for ovarian cancer revealed several calcified lymph nodes in my right lung and another unidentified small mass that isn't necessarily calcified. I don't have an appointment with a pulmonologist until June 17th and I'm just worried. Will they for sure want to biopsy it? How else will they know for sure what it is? And if they do a biopsy, how is that done? Does it take long? Does it hurt? Any help would be much appreciated. Thanks!
