I noticed a left thyroid mass May 2019. The ultrasound on July 9 comments were that there is a predominantly solid left thyroid mass with some cystic components measuring 5.4 x 3.4 cm. There is a 12 mm cystic solid mass in the interpolar region on the right side. On August 9, a needle biopsy was carried out of this mass and was described as a follicular lesion of undetermined significance. TSH level was 1.65 mU/L, T4 Free 12.0 pmol/L, T3 Free 4.9 pmol/L on Sept 9. I am told that at minimum I will require a lobectomy. Is this the only option, or is it possible to shrink the mass in some other way by way of diet?
