A lot of people have nodules and usually more than one is better than just one. Regular ultrasound to watch if it changes in size is advised . They do not always turn cancerous and if so thyroid cancer is one of the slower growing ones but it’s nothing to be complacent about if it is cancerous.
I had a total thyroidectomy after my third bout of Graves’ disease . It had nothing to do with the 3 nodules I had on my thyroid. They never changed in size over 30 years but the medications that I could use for my Graves’ disease ( 2 available) had other issues. When I was 30 after the birth of my son I had a racing heart , lost a ton of weight very quickly , could not sleep and then I had to sit up as I felt my heart was going to jump out of my chest, my hands were a bit shaky and when I tried to do anything I was exhausted. Blood tests proved I had Greaves disease . After 14 months of medication it went into remission and then a well meaning natural nutritional therapist told me I should take lugils iodine ( just a few drops a day) . It’s good for both overactive and under active thyroids . She quoted a book by a dr Bronstein or something, but it wasn’t . My endocrinologist said get off it straight away. I had another 15 months before it went into remission. It was the third time that things became much more serious as there are only 2 medications for it and the first one I had previously had success with I now had developed an allergy to and the itch was unbearable so I stopped after a few days and changed to the other one and I was having regular blood tests but within that one month it knocked out my immune system and I was in isolation getting intravenous antibiotics and getting me well enough for surgery. I was worried about the surgery but knew I had a good female surgeon that answered all my questions . They have a device that lets them know where the nerve to your voice is located which is extremely important and I was lucky she could save my parathyroid glands . They didn’t work for a couple of months and I needed calcium supplements and vit D until they did. I now take one thyroxine tablet in the morning. My best friends son was born without a thyroid and all babies are tested at birth .
What I am trying to say is that cancer of the thyroid is a slow growing one but still if it tests as cancer it is darn serious and a bit of this or that is not going to get rid of it . Be careful and cautious but if it’s cancer you don’t want to give it a chance to spread when it can be taken care of and you can live a carefree life . Once you let something spread its a very different story especially if a biopsy shows cancer. All the best and get extra options and tests if needed so you can make an informed decision. Good luck.
