Grammy winner John Mayer canceled his spring tour because of a recurring vocal cord illness.

Mayer had surgery in October to remove a granuloma, or benign growth, on his vocal cords. Mayer and British singer Adele, who had similar surgery last fall, have the same doctor, RadarOnline reported. Mayer, 34, said Friday that he would be canceling his 21-city tour to promote his fifth studio album, Born and Raised, to rest his vocal cords.

Mayer was to headline Stubb's Bar-B-Q in Austin, Texas, on March 17 as part of the South by Southwest music conference, but that show was also canceled, according to news reports.

Nothing feels worse than having to break the stage down before the performance, and I mean nothing, Mayer said in a statement to fans on his tumblr blog. I love this band you were going to hear, I love the guys and girls I work with, and the only thing that stops me from devolving into a puddle of tears is knowing that it's a long life, and the greatest gift in the world is being able to create music no matter what the circumstances.

In a post on his tumblr blog Friday, the singer said that during rehearsal on March 6 something didn't feel/sound right, and he went in for a visit on Wednesday and a scope of my vocal cords revealed that the granuloma has grown back where it had mostly healed.This is bad news.

Because of this, I have no choice but to take an indefinite break from live performing. Though there will be a day when all of this will be behind me, it will sideline me for a longer period of time than I care to have you count down.

Columbia Records will release Mayer's new album Born and Raised on May 22.
