Most patients with thyroid cancer have the cancer contained in the thyroid at the time of diagnosis. About 30% will have metastatic cancer, with most having spread of the cancer to the lymph nodes in the neck and only 1-4% having spread of the cancer outside of the neck to other organs such as the lungs and bone.

Follicular lymphoma (FL) is a slow-growing type of non-Hodgkin lymphoma. It develops when B-cells (also called B-lymphocytes) become abnormal. B-cells are white blood cells that fight infection. The abnormal B-cells (lymphoma cells) usually build up in lymph nodes, but they can affect other parts of the body.

MTC is a rare tumor that arises from neural crest-derived parafollicular C cells.
