Mine did too .. clusters are more than "rare clusters" from what I understand .. a good am't of cells present like this .. mine turned out to be benign upon partial thyroidectomy but they ended up finding two other small cancer findings elsewhere in the gland so I'm glad I had it out. My pathologist , who I met in person, said 25% of atypical cells turn into cancer if left intact.
