>some of this medical jargen is like a foreign language at times
The medical profession has a good case of the Latin'atitus.
PS: Good luck. I went through this in February, so I did a lot of researching.
Thank you for the ingormation! Even tho I am a nurse some of this medical jargen is like a foreign language at times. And I always think the worst. I have been having s/s of hypothyroidism. I go for lab work same day as biopsy. Hopefully everything turns out good. Thanks again!
Simple answer: You have a single 16mm nodule in your thyroid. With some cystic degeneration happening. Probably 95% chance the nodule is just a benign thyroid nodule. These are very common. 50% of people have some nodules in their thyroid by the time they are 60.
Maybe some signs of autoimmune disease, likely not though.
Worrying about an FNA biopsy: I've had this done a couple of times. Usually isn't a big deal despite seeming rather gruesome. The do a local and then use a very fine needle to snag some cells to look at. When I had mine done it didn't hurt and I had at most a sore neck the day after. Other people say the same thing. So I would try and relax.
Bring up the C word. In general thyroid cancer is highly curable. The two most common types have a cure rate of nearly 100%. A less common type (3% of cases) medullary thyroid cancer isn't as good, but still usually over 80% cure, higher if it hasn't spread.
Treatment for thyroid cancer is they remove your thyroid and usually give you a single dose of radioactive iodine to kill stragglers. Since most thyroid cancer takes up iodine it's very effective. Thyroid surgery is a delicate operation that must be done by a trained surgeon. But that has few complications and is nearly an outpatient procedure.
If the FNA comes back benign the usual thing to do is to check it again via ultrasound in six months and then every year thereafter. If it gets bigger they may do another FNA. Scuttlebutt now days is benign thyroid nodules don't 'turn into cancer' so don't worry about that.
If the FNA comes back insufficient, means they didn't get a good sample and they need to do another FNA. (Happened to me twice)
PS: This all assumes your thyroid labs are normal, not elevated.
Good luck.
