"I feel fortunate that my cancer sent me an alarm call in the form of 'the cough that wouldn't quit,'" Campbell said.
He still plans to tour with the band, beginning June 21 at the Hellfest music festival in France, and concluding July 17 in Canandaigua, N.Y.
An English rock band, Def Leppard formed in 1977 in Sheffield. Campbell joined the band in 1992, after the release of the album "Adrenalize." He replaced Steve Clark, who died in January 1991 due to a combination of alcohol and multiple prescription drugs.
Campbell had also been a member of Whitesnake, Sweet Savage and Thin Lizzy.
Def Leppard's biggest commercial success came in the 1980s and early 1990s. Their fourth album, 1987's "Hysteria," topped the U.S. and U.K. charts and has gone on to sell more than 20 million copies worldwide with songs that included the Hot 100 Billboard No. 1 song, "Love Bites," as well as "Pour Some Sugar on Me," "Hysteria" and "Armaggeddon It."
Overall, the band is one of the world's best-selling music artists, having sold more than 100 million albums worldwide.
