Thyroid sonogram found 13mm oval mass with increase vascularity and punctate calcifications complicated cyst where also present. cancer risk?

High enough to be : Further evaluated. Risk of cancer is not very high, but too high to ignore. An more definite risk determination would require review of the images, as well as lab work and history and physical. Please see an endocrinologist (unless you already have). The described us appearance is not definitely benign and a fine needle biopsy should be considered.

Potentially: You need lab tests and a thyroid biopsy. Check w/ your doctor.
