Thyroid Ultrasound results

[pgpapergirl]

Had a ultrasound done of my thyroid just a couple of weeks ago.  Results were right lobe measures 4.6 x 1.4 x 1.8 cm with a complex solid and partially cystic nodule towards the upper pole measuring 1.0 x .07 cm.   Left lobe measures 3.6 x 1.5 x 1.6 cm.  Mentions a couple of hypoechoic nodues on either side.  Isthmus measures 3 mm.
What do they mean and should there be further testing done.  I am a 10 years breast cancer survivor.

Given the history of breast cancer and radiation treatment(?) the nodules have to be monitored with Doppler flow of complex (dominant) nodule; if changes observed biopsy is needed
