You should have a biopsy just because of the history in your family. Most definitly and certainly if the radiologist said possible malignacy. That is crucial you get this done yesterday if not sooner.
Good Luck to you!

WHY HAVEN'T YOU HAD A BIOPSY???? It is relatively painless, and can tell you most times if it is cancer. If you have a history of thyroid cancer, what are you waiting for? A spanking? Well here it is!!! GET A BIOPSY!!! I have Papillary cancer, my sister has it too, my other sister has nodules and is being tested for cancer, two of my brothers (so far) have Hashimoto's as did my Dad. Don't you see the family connection? Stop watching and take some action on this, it could mean your life.
