Def Leppard’s Vivian Campbell had a bone marrow transplant for his cancer treatment

Def Leppard guitarist Vivian Campbell has shared an update about his health.

The rocker missed the band’s Jan. 18 concert in León, Mexico, with frontman Joe Elliott explaining he was “recovering from some treatment for his cancer.” Well, now Campbell has taken to social media to thank fans who have reached out and to share some good news about his condition.

“Thank you for all the recent messages and support. As you all may know, I was diagnosed with Hodgkin’s lymphoma several years ago,” he wrote on Def Leppard’s Instagram page. “I recently had a bone marrow transplant as part of my treatment plan, and it’s safe to say that thus far it’s been a very successful transplant!”

“I just have to keep my head down and my spirits up for the next 100 days of primary recovery,” he added, signing the post “A very happy Viv!”

While Campbell was replaced at the Mexico show by Phil Collen’s guitar tech John Zocco, it looks like he’ll have plenty of time to recover and make the next one. Their next show isn’t until May 15 in Puerto Rico.
