Thanks for your responses...trying not to worry!!!
If solid mass has NO blood flow, it is very likely to be benign [95%]; even with blood flow AND calcifications it has 22% chance of being malignant.
Try to relax and not think the worst.....I had complex nodules that turned out fine with biopsy. The biopsy wasn't a bad experience for me and the scariest part was my mind wandering and worrying. The good news is that IF it was thyroid cancer, it is one of the easiest cancers to cure.
