Icelandic pop singer Bjork announced on her website that she underwent a successful surgery on her vocal cords.

The singer of hits such as “Army of Me” and “Hyperballad” had been diagnosed with polyps on her vocal cords several years ago, and she attempted to manage them by changing her diet and working out.

However, the polyps eventually became bad enough that Bjork had to cancel several concerts “and Biophilia residencies in Argentina, Brazil, Spain, and Portugal due to having inflamed vocal cord nodules,” according to the Inquisitr.

Bjork announced her successful vocal cord surgery in a blog post entitled “Dear Friends” on her website.

The 47-year-old singer wrote: “[F]ew years ago doctors found a vocal polyp on me chords … i decided to go the natural way and for 4 years did stretches and tackled it with different foods and what not. Then they discovered better technology and I got tempted into hi tech lazer stuff and I have to say, in my case anyway: surgery rocks! I stayed quiet for 3 weeks and then started singing and definitely feel like my chords are as good as pre nodule! It´s been very satisfying to sing all them clear notes again. im sorry i had to cancel stuff earlier in the year, didn’t want to talk about this until i knew for sure if it would work.”

Bjork got her start playing in the Icelandic punk band Kukl, touring with influential anarchist-punk act Crass. Eventually, she formed The Sugarcubes, and ultimately embarked on a successful solo career.
