I have recently had two biopsies on my thyroid and
Hello and thank you for asking!
I have gone carefully through your concern.
The decision to go for surgery ( when biopsy is not conclusive) depends mainly on the nodule characteristics in ultrasound, secondly if there is a tendency to increase the dimensions more than 20% in 6 months.
So, if the nodule has characteristics in ultrasound that score more than TIRADS 3, than the chances to be malignant are higher.
Having into consideration her age, the surgery is not that easy and i would suggest for a second opinion before you decide for thyroidectomy.
Hope the information will help.
