Brooke Burke-Charvet Scar

Brooke Burke-Charvet Scar (January 9, 2013)

Brooke Burke-Charvet displayed the scar from her thyroidectomy Tuesday on "Good Morning America," admitting that the makeup-free show-and-tell was a first for her, as she'd been "scarfing it up" — as in, covering it up — until now.

"But you know what," she said, "it's fresh, it's a month old, and I think scars tell a story, and I'm so fortunate."

The "Dancing With the Stars" co-host revealed her thyroid cancer diagnosis in early November through a video posted on her blog. She underwent surgery in early December and shared the news a week later that she was cancer-free.

In her initial video, the 40-year-old mother of four appeared very concerned about scarring, saying, "I need to have thyroid surgery, have a thyroidectomy, which means that I'm going to have a nice big scar right here across my neck. It is taking me a couple of months to really wrap my head around this."

But her blog post from last Friday revealed a new attitude, in line with how she presented herself on the morning news show.

"[I]t’s over, and I can happily say that I kicked Cancer’s a*&!," she wrote. "I am feeling fantastic! Aside from a little scar, I am good to go."

The good attitude wasn't something that came out of the blue, however.

"Fortunately I did a lot of research and I knew that the prognosis for thyroid cancer is really excellent," she said on "GMA," where she discussed promising her oldest child that Mom would be fine. "I knew that I was going to be OK. but I was also very fortunate that i was responsible enough to do a regular physical and then take action."

Burke-Charvet will co-host the 2013 Miss America pageant on Saturday.
