As you read the posts in these discussions you will meet others with the same diagnosis and many who have had different treatments. Feel free to post comments or questions as you read the posts.

As this is a recent diagnosis for you, what type of treatment is being planned?

I have my first appointment with the head surgeon of endocrinology at UofM on Dec. 18th. Right now it looks as though they will be removing my thyroid and any lymph nodes they may need taken out.

I had surgery for medullary cancer. It was a modified, radical neck resection. Are you scheduled for surgery?

Im so sorry you are dealing with this with your Mom. My heart goes out to you. I lost my sis years ago from brain cancer. It is such scary stuff! Please feel free to contact Brant me if I can maybe answer questions for you. 🥰
