Re: what size nodule is too large
1 cm diameter nodules warrant needle biopsy evaluation. When you get a nodule the size of yours, it is a hazard to your breathing, eating, and vocal cords. It is also under greater suspicion for being a bad growth. The only 100% way to determine if a nodule that size is malignant/bad is to remove it so a total biopsy of the tissue can be performed. In needle biopsies they only spot check the nodule and pockets of malignant tissue may be missed.
My mom had a PT and was just fine, I have had two aunts have TTs. They came out just fine as well.
If we learn by our mistakes, I am working on one hell of an education.
