Hey, I am following this post... I looked up exactly what this was because I am not familiar. This is what I have found: Background:
“Thyroid nodules diagnosed as Bethesda category IV (follicular neoplasm/suspicious for follicular neoplasm (FN/SFN)) are recommended for surgery. However, only 25% of these nodules turn to be malignant on histopathology. Therefore, selection of nodules for surgery diagnosed as Bethesda category IV is important. We aimed at to define the predictive factors for malignancy and predictive risk indices for selection of surgery.”
This is the website I found it on. Your doctor should update you, but follow up with your doctor, and stay on them. Best wishes to you.
