Thyroid Ultrasound

[are1982]

Hi My name is Ronda.  in 2008 I had part of the right side of my thyroid removed due to a single nodule that turned out to be benign.  In October I had an ultrasound of my neck because it appeared to be enlarging again and was found to have  multiple bilateral thyroid nodules.  The largest nodule on the right measured 1.4x1.4cm and the largest nodule on the left measured 1.9x1.7cm.  The multiplicity of nodules suggested adenomatous nodules but because of the size they were biopsied and found to be benign.  

Skipping forward 8 months I had a follow-up ultrasound that now shoes there has been interval increase in size of 2 nodules in the inferior pole of the left thyroid lobe.  One has increased from 1.9 x 1.7cm to 2.6 x 2.7cm and the other has increased from 1.4 x 1.0 cm to 2.0 x 1.5 cm.  The nodules on the right side are stable.    Is this concerning for thyroid cancer?  What next steps are warranted.  Should I have it biopsied or just removed?

correction - a significant increase is more than 20% in two or more dimensions and a 50% increase in overall volume.

A repeat biopsy may be warranted based on the increase in size (>50% increase in two or more dimensions).
