(CNN) -- Acoustic rocker John Mayer has bowed out of a series of concerts after suffering from "something next to my vocal cords called a granuloma," he said in a statement released Friday.





The singer and songwriter said he had undergone months of monitoring, but the condition -- a small area of tissue inflammation that most often occurs in the lungs -- had prevented him from going ahead with the performances.





"I'm bummed to have to bow out of both the iheartradio Music Festival in Las Vegas and an appearance with Tony Bennett in Los Angeles," he said in the statement. "I know there were people depending on me to be there and I'm sorry that I can't be on those stages."





Mayer's soon-to-be-released album "Born and Raised" also will be delayed.





It's "complete as far as music recording, song selection, and in some cases mixing," he said. "But because of this condition I couldn't finish singing on several of the tracks."





The album, as a result, will be released next year "instead of this fall or winter."





"This is a temporary setback, though I'm not sure how long or short a period of time it will be," he said. "I've got the best doctors in the country looking after me and I will be singing and touring again as soon as I get the all clear."





Mayer said he plans to spend the down time writing and composing, and "kicking an empty soup can around the West Village."
