I did not get a second opinion. I was diagnosed by my pcp and was moving to Milwaukee when I was diagnosed. I ended up going to Froedert medical college. I saw a board certified endocrinologist who specializes in thyroid cancer. I trusted what I was told. My cancer had spread to 9 lymph nodes, so a total thyroidectomy was necessary. My advice is to find a someone who specializes in thyroid cancer. My pcp in MN would have treated me has I not moved and I have no doubt I would not have received the proper care. I moved back to MN and my pcp took over my thyroid care and I went through a year of my TSH being on a roller coaster. I gained 7 lbs, lost a lot of hair, it is not fun. See an endocrinologist for sure. Surgeons don’t always have the best communication skills, so keep that in mind. Definitely find someone who is a pro at this.
