Enlarged thyroid but my blood thyroid test was normal.?

It can be enlarged or you can have thyroiditis without it afecting thyroid hormone output. I wouldn't worry, they wouldn't have said what they did if they suspected cancer from the ultrasound.

I had the same problem a few years ago (but i was really sick) The growth on my thyroid ended up being goiters...which are completely harmless unless they prevent your thyroid from functioning properly. I was diagnosed with graves disease and had to have my thyroid removed so hopefully you don't have to go thru that process!! If your blood test (tsh, t3 and t4) are all normal then i wouldn't worry too much, could even just be a cystic mass. Good luck!

I have an enlarged thyroid and all my blood tests were fine too. After my ultrasound scan they said it is a benign goitre which means I have no lumps etc on the thyroid and there is no obvious cause. However I have no iodine source in my diet and am experienceing a few other symptoms of thyroid problems so am now taking an iodine supplement and am going to see if that makes a difference.

One of the reason could be fluoride that displaces iodine in the thyroid and creating the "iodine deficiency". "This common additive to your water supply, and ingredient in the toothpaste you and your children use may be contributing to the increased rates of goiter and hypothyroidism -- and other health concerns -- in the U.S. . . without improving dental health."

Sometimes a disease called Hashimoto's thyroiditis is to blame.
