If i have a 32mm solid hypochoic thyroid nodule what is the likelihood it is cancerous?

Most of them benign: Then is it is good , they are very common , filled with fluid. Don't be afraid most of the time they are benign , but yet need close observation or aspiration with fine needle and analysis of fluid to make sure no tumor growing inside that cyst.

Needle aspiration: Determination of solid thyroid nodules' true nature requires a fine needle aspiration. Most biopsies are benign. Learn more about ultrasound guided biopsies and aspirations here: http://www.Conciergeradiologist.Com/ultrasound-guided-biopsy.Html.
