Miley Cyrus says she has Reinke's edema, a disorder that makes her voice "super unique"

Miley Cyrus has opened up about her experience with Reinke's edema, a vocal cord disorder that she says causes her signature sound.

During a recent interview on Apple Music's "The Zane Lowe Show," the singer, 32, described the disorder as "abuse of the vocal cords."

"Being 21 and staying up and drinking and smoking and partying after every show does not help. But also, in my case, it does not cause it. My voice always sounded like this, so it's a part of my unique anatomy," she explained. "So I have this very large polyp on my vocal cord, which has given me a lot of the tone and the texture that has made me who I am."
