Doctor last year I went for usg neck as a was having swollen lymph nodes and incidentally a small hypoecoic nodule 4*3 mm was seen in thyroid. That time the doctor told me not to do anything with it . Sir just out of curiosity yesterday I went for an usg to check the nodule and the usg report shows that a small benign hypoecoic nodule 3*2 mm is seen. Sir my thyroid blood report is normal also.. doctor is it something serious ?? As I can see according to the usg report the size of the nodule has reduced in 1year .. will it resolve on its own? Or should I do something with it??
