About two years ago while having a scan for something else, they found I had a goiter with multiple nodules. I had ultrasounds every six months until last year when my new ENT told me to wait a year to have another. I had the scan this month and one of the nodules had increased from 4mm to l.5cm. They promptly scheduled a biopsy but the doctor was unable to get enough cells to diagnose after going in three times. My primary care doctor told me to have another scan in six months, which would be fine except that I am concerned since I have pressure in my throat, choke frequently (not eating, just saliva) and am hoarse all the time. Neither my primary care doctor nor the ENT seem concerned about it, saying it's probably acid reflux because my goiter isn't enlarged enough to cause these problems. However, the GI doc she sent me to doesn't think reflux is causing my problems. Should I insist on another biopsy immediately or wait a couple of months and schedule another scan?
