I have a thyroid nodule which has a lot of vessels in and around it, the ultrasound report also said it has regular shape and contour, and the size is about 1.0*0.5*0.8 cm. The echo is heterogeneous and hypoechoic, and the lymph on my neck seems normal. The blood test result of it is normal. Do I have to do a FNA? Basic Info and History: I am a 22 years old female. I had several X-ray for my teeth when I was ab 13yr. My grandmother and two aunts all have thyroid nodules. Thank you very much.
