In brief: Depends
Depends on the size of the nodule.
In general, the larger the nodule, the higher the risk of false negative (that is, the more likely it will be negative although it could still be cancerous). This is why we continue to follow the nodule with ultrasound even after a negative biopsy to make sure it's not changing in size in the future. If it grows in time, you might need another biopsy.

In brief: Depends
Fn biopsies are directed to individual nodules.
Do it depend ls on if you have just one nodule or multiple nodules. Thyroids with multiple nodules are less concerning for cancer.
