It is a long story but 10 months ago I had a chest ct scan, it showed enlarged mediastinal and hilar nodes 1.5cm on the short axis. I was not able to do the post f/u due to an injury and surgery that had me non weight bearing, my PC received the results but never followed up until I had my check up in Oct and I mentioned it. He was very concerned sent me for CT scan #2 which showed the same results with the hilar being 1.9cm . The impression was possible sarcoidosis or indolent lymphoproliferative process. I am headed to the pulmonologist on Tuesday. I am not sure what comes next my P. C. indicated he thinks a biopsy would be next since I have had 2 c. t. scans. What questions should I ask, which test should be scheduled? I am a 63 year old female who walked 2-5 miles 3 or so times per week but I am tired and lately getting to 2 miles really zaps me, but I also think the mental game of knowing something could be seriously wrong possibly is getting to me. I was very tired before I knew the nodes were still enlarged. It is a little crazy because I have let myself leap right into the rabbit holes on google.
