HI, Welcome to HCM, I am Dr. Das.
FIrstly, FNAC is a just tool which gives us a rough idea which should be kept in mind during diagnosing a disease. But, The diagnosis which is given in FNAC, must be confirmed in biopsy
done from that area. And in case of thyroid
, one problem is presence of different disease in different parts of one thyroid tissue .
So, first consult with a general surgeon
who will go for removal of thyroid and then wit for the biopsy report which will confirm the disease and then only treatment should be started.
No treatment should be given ony on the basis of a FNAC report.
