Welcome - Happy New Year!
The fact that you have two, relatively small nodules is a good sign. It's the singular nodules that *can* be of concern for thyroid cancer.
The 1cm nodule will most likely be biopsied, just to play it safe.
Reece on here knows a lot about nodules and I defer to her additional comments.
I must admit that the title of your thread really got my attention. While it doesn't seem you have Graves', the labs you posted did not indicate that you were tested for it. A TSI (thyroid stimulation immunoglobulin) or TRab (TSH receptor antibody) test is the only definitive test for Graves'.
However, the fact that your TSH, FreeT4 and FreeT3 all fell within the normal range indicates you're not dealing with Graves'.
And, just because you tested negative for the antibody test results you shared doesn't necessarily mean you don't have Hashi's....I hope not but, just wanted you to know that many people with Hashi's test negative for the antibodies.
Now, back to your TSH, FreeT4 and FreeT3 that all fell within the normal range. Please know that having levels within the normal range is fine *if* you are not dealing with any symptoms.
Now, you didn't mention symptoms so, I hope all is well for you in thyroidland. If you are dealing with any of the symptoms mentioned in this thread:
I suggest you share the actual results of your TSH, FreeT4 and FreeT3 tests (with ranges since they vary from lab to lab).
We can show you how to interpret them.
