Thyroid Nodules

I have had a goiter for many years.  About a year ago, during a CT scan, several nodules on my thyroid were discovered, one of them was large.  It was checked again, six months later and it had gotten bigger.  The doctor did a biopsy and it was negative. I was told they it should be checked again in six months. I just had it checked about a month ago and it is more than twice the size it was.  I am scheduled for another biopsy in 2 weeks.  I just wondered how serious this is.  Is the fact that the biopsy came back negitive before a good sign?  What would make this nodule grow so fast?

The most common reason for rapid growth would be bleeding into the nodule (sounds worse than it is) resulting in increased size temporarily then the body resorbs the blood.  It could also have a significant cystic fluid (blood or thyroid fluid) which can increase in size and usually are benign.  Ask for the biopsy report - this is important in determining how suspicious it is.  Also certain features on ultrasound are important. I agree with the repeat biopsy.  

Rapid growth of a solid nodule (ie, no cyst fluid) may prompt consideration of surgical removal - start with the repeat biopsy and let us know what happens. If there is a family history of thyroid cancer or a history of radiation exposure to the neck (not routine x-rays -- I mean radiation treatment of some type - esp as a child) then would also consider surgery.

I had a FNA biospy.  The result came back "suspisious".  I go Friday to see a surgeon.
