Most thyroid nodules are benign but FNA biopsy is needed to make this diagnosis. Usually the needles are smaller than blood draw needles -- at least the ones we use are -- and the biopsy should not be traumatic. Even in if this is cancer, the survival for a young person is excellent. Thyroid surgery does not make people fat -- the thyroid levels will be restored with thyroid medication and there should not be significant weight gain. Patients often assess weight gain to the thyroid, but in reality, it's that they are eating more calories than they need and metabolism slows w/ age.
Thanks a million Dr. Lupo with your medical advice and the other patient that also answered as my question as knowing from her own experience I feel confident this will help relieve the anxiety my fiance is feeling and we can get on with the treatment with a postitive attitude. I appreciate your time. Thanks again!
