@fcast1334, getting a rare diagnosis is scary. But you are not alone. You can connect with others who have experience with Anaplastic Thyroid Carcinoma in this discussion:
- Daughter, 45 anaplastic thyroid cancer. Had surgery, chemo, radiation. https://connect.mayoclinic.org/discussion/daughter-45-anaplastic-thyroid-cancer-had-surgery-chemo-radiation/

As you prepare for your meeting with the medical oncologist, here are some questions you might wish to ask:
What stage is my thyroid cancer?
What treatments do you recommend?
What are the benefits and risks of each treatment option?
I have other health problems. How can I best manage them together?
Will I be able to work and do my usual activities during thyroid cancer treatment?
Should I seek a second opinion?
Should I see a doctor who specializes in thyroid diseases?
How quickly do I need to make a decision about thyroid cancer treatment? Can I take some time to consider my options?
What might happen if I decide to have regular checkups but not have cancer treatment?
Are there any brochures or other printed material that I can take with me? What websites do you recommend?
Am I able to access my medical records through an online patient portal?

Sending you warm wishes for the holidays and hope you will have time to spend with family and not think about cancer.
