Does anyone have a goiter (thyroid lump) ?

I have a rather large goiter (thyroid lump). Every time I go to the endocrinologist he asks if I want it taken out. I keep saying no. I don't want surgery and I don't want to be on medication for the rest of my life (I cannot swallow pills - ugh).

I am researching food sources to see if I can handle it naturally.

Does anyone have the same problem and any advice ? Thanks.
