Glastonbury appearance
Further information about the possible impact on other tour dates would be announced in due course, a statement on the band's website added.
The Irish rock band was due to perform a string of gigs across North America, returning to Europe in August.
They were due to begin rehearsals on Tuesday for the opening date in Salt Lake City, and are scheduled to headline the Glastonbury Festival on 25 June.
U2 manager Paul McGuinness said of the tour: "We will make plans to reinstate the dates as soon as possible."
He added it was "unfortunate that we're inconveniencing fans" and that it was causing disruption to the band's 400-strong crew.
He advised fans to continue monitoring the U2 website for further news.
