Re: U/S and Scan Results- Please Help Explain
Sounds like you have the very common, "multinodular goiter"---a lumpy bumpy enlarged thyroid. It's usually from thyroid disease. If there are larger more dominant nodules they usually do a needle biopsy to get more information of what kind of cells might be in there.
These are usually benign. After the fna, if everything is fine, they will watch it for growth and changes. You should also consider taking thyroid hormone, as it may help it shrink.
In the worst case, if you had to worry about thyroid removal, it's not usually a difficult surgery. I don't think you have to worry about cancer, but if you did (which you don't at this point), it's an easily treatable, and usually curable cancer, I had it over 6 years ago, and thankfully no worse for the wear.
