I got my ultrasound results today..I have goiter. My doctor

I got my ultrasound results today..I have goiter. My doctor suggested that I have surgery as opposed to the iodine radiation. She said 2 of the nodules were about 1 inch big, and that the radiation would make them smaller but not much. I go for my biopsy on the 31st. Should I get another doctor's opinion?

I think for surgery, a second opinion is always wise.

@CKarma thank you
