Dancing With the Stars co-host Brooke Burke has cancer. The 41-year-old mother-of-four [she's 41?!] shared the news through a video on Thursday.

Brooke has thyroid cancer and said, "I need to have thyroid surgery, a thyroidectomy, which means that I am going to have a big scar across my neck.

Brooke promises to be a "good patient" and added, "I've never felt better. That's what's so crazy about this whole thing."

 Our best wishes to Brooke.
