Brief Answer:
Thyroid

Detailed Answer:
I understand what you are saying here.

Yes I agree that logically there is a decreasing trend of the TSH.
However please note that there is roughly a 20% variation in TSH even in the same blood sample, each time it is tested. Hormones are complex things to measure and that is why one of the golden rules of endocrinology is to by trends and patterns rather than just a hard number.
Your TSH trend is in the normal range although I agree it is on the lower side.
The vast majority of individuals I see with this type of thyroid blood test result, are normal in terms of thyroid status.
That being said, I like to order a blood test called Free T4 in addition to TSH which gives a better idea regarding the overall thyroid status, especially in circumstances like yours where greater clarity is desired.
Further tests are considered only on the basis of a comprehensive physical examination.

Detailed Answer:
I have noted your thyroid auto antibody results which are essentially negative.

Whether or not thyroid removal is necessary will depend on a host of factors of which ultrasound and FNA are very useful tests.
