Thanks for the query to H.C.M. Forum. Thyroid nodule
is a discrete lump noted on palpation of the thyroid gland.
Since , you mentioned that three biopsies reports are inconclusive , so this is a good news.
In October thyroid was increasing in size but not significantly, so what is about tumor
( lump or nodule) . Red chest is not significant until some symptoms are not there.
If you have any report ( recent ) of tumor than upload it , otherwise wait and watch.
Hope I have answered your question.
If further any question I will help.
