Vivian Campbell Vivian Campbell

Def Leppard guitarist Vivian Campbell has been diagnosed with cancer, but still plans to tour with the band this summer.

In a statement posted on the band's Facebook page, Campbell, 50, said he's one-third of the way through a six-month chemotherapy treatment for Hodgkin lymphoma. "I feel fortunate that my cancer sent me an alarm call in the form of 'the cough that wouldn't quit,'" Campbell wrote of his early diagnosis.

"The reason I'm sharing this with you is because, despite cancer and chemo, me and my new aerodynamic hairstyle (read: no hair) are going on tour this summer with the band and I don't want anyone to be so shocked by my new look that they ask for a refund," he wrote. "Simple economics, really."
