LOS ANGELES (REUTERS) - Green Day guitarist Jason White has been diagnosed with a form of tonsil cancer that is treatable, the rock group said on Monday.

Doctors found the cancer while White underwent a tonsillectomy, the band said in a statement posted on its website.

White, 41, is expected to make a full recovery, Green Day said.

The guitarist has played with Green Day since the late 1990s but did not become a full member until 2012.

The band, known for its 2004 American Idiot album, is fronted by guitarist-singer Billie Joe Armstrong. It found mainstream success as a punk rock trio with its 1994 album Dookie, which had several MTV and radio hits including Basket Case and "When I Come Around.

The band is expected to be in the running for induction into the Rock and Roll Hall of Fame in Cleveland, Ohio next year.
