I've been a rock star since you were very young. But I've never encountered anything as powerful as cancer.

Once I overcame breast cancer, I wasn't afraid of anything anymore.

I've worked since I was 11 years old, playing music and following the dream, and shaking and moving and doing it. And then, you have cancer and it was like 'Ooooohh.' It was like a big eraser. It was the only thing in my life that had ever made me just stop.

I'm very fortunate that I have a wonderful family around me and loved ones.
