Have a "cold" thyroid nodule <3cm. dr wants biopsy but i suggest surgery to get it over with. what do you suggest?

Follow your doctor's: Advice. Discuss with your doctor if he would do a needle aspirate first an a biopsy only if needed. Thyroid nodules are often multiple and removing the largest one may not address the issues. See this site for more info. http://www.mayoclinic.com/health/thyroid-nodules/ds00491/dsection=tests-and-diagnosis.

Don't Rush Surgery: A cold nodule on a nuclear scan could merely be a colloid cyst which is very unlikely to be of any concern. Thyroid ultrasound done before and during a needle biopsy will further characterize the nodule. If the nodule is solid then a needle biopsy will help guide any further treatment. Surgery on the thyroid is not without risk and should be undertaken only for a good reason.

Biopsy: The biopsy to determine if the nodule is malignant is way less invasive than surgery. I would suggest biopsy.

Biopsy: Most of the cold nodules on thyroid scans are benign but cancer has to be ruled out. Thyroid biopsy is a relatively noninvasive and simple procedure to perform and can give the answer. I would definitely suggest to start with a biopsy as an initial step. Then , if it is inconclusive or you feel very uncomfortable, talk to your physician. Good luck.
