What is anaplastic thyroid cancer?

Aggressive: Be sure the diagnosis is made by at least two pathologists who agree. Anaplastic thyroid cancer / carcinoma is an aggressive disease with no known risk factors (except perhaps a tiny pre-existing low-grade tumor too small to feel). It seems to strike adults at random and is not one of those cancers that are easy to treat.

An aggressive tumor: This is an aggressive form of thyroid cancer that can come back rapidly and is general treated with a combination of surgery, radiation therapy, and chemotherapy.

Very bad cancer: This is a rare form of thyroid cancer with a poor prognosis. If you or someone you know has this diagnosis, he/she should seek help from a head and neck surgeon, a radiation oncologist, and a medical oncologist asap.

Anaplastic carcinoma: Anaplastic thyroid cancer is the most aggressive and most lethal form of thyroid cancer. It is almost always universally fatal. Chief Justice Renquist died of this shortly after the 2nd inauguration of George W. Bush.
