No diagnosis yet. The petscan showed a lymph node as "hot", but not the ground glass lesion! I had a needle biopsy of the errant lymph node, but there were no clear cut results. Then they advised an excisional biopsy of the lymph node, but the surgeon said that if they couldn't find it, the risk of edema, etc would go from 3% to 30% if they just took several nodes. I decided the middle route was an ultrasound of that area before surgery. All this has taken about 3 months; finally got the referral but no ultrasound until March 17. So, long story, short, I am still on the journey. I have nodules in both thyroid and lung.
