Singer Bjork undergoes throat surgery

  • Singer Bjork announced on Friday that she underwent surgery to remove a polyp on her vocal cords.

    The Icelandic musician said she had been trying to manage the polyp, which was discovered by doctors four years ago, through diet and exercise.

    The 47-year-old decided to undergo laser surgery this year after being forced to cancel performances of her Biophilia show in April.

    "I have to say, in my case anyway: surgery rocks!" she wrote online.

    "I stayed quiet for three weeks and then started singing and definitely feel like my cords are as good as pre-nodule," the singer added.

    Bjork opened her latest world tour in Manchester, England in July 2011.

    Last October, she released Biophilia, a concept album about nature and science.
