For Vivian Campbell, continuing to step onto a stage has become about far more than playing guitar.

The longtime Def Leppard musician has revealed that his cancer has returned after a donor transplant failed to produce the lasting result he had hoped for. Yet even as he continues treatment and looks toward another transplant in the future, Campbell says music remains one of the forces giving him a reason to keep moving forward.

The update marks another difficult chapter in a health battle that Campbell first made public more than a decade ago.

Campbell, who joined Def Leppard in 1992, announced in 2013 that he had been diagnosed with Hodgkin lymphoma. The disease later went into remission, but his condition eventually changed again — and by the winter of 2023, he said the situation had become frightening enough that he began to fear for his life.

A Turning Point in the Winter of 2023

Campbell described that period as the only point during his illness when he truly believed the cancer might kill him.

What alarmed him was not simply that the disease was present, but how quickly things appeared to be progressing.

He said he became deeply concerned about both what was happening and the pace at which it was unfolding. That realization led him to conclude that a donor transplant was no longer simply another option. In his mind, it had become his best chance of surviving.

Campbell underwent the transplant, hoping it would provide a long-term solution.

It did not.

The guitarist later explained that the transplant “didn’t stick,” and the cancer returned. He is now continuing treatment aimed at managing the disease.

That setback could easily have changed the way Campbell approached the years ahead. Instead, his comments suggest that he is trying to live alongside the uncertainty rather than allow it to dominate everything else.

He said another transplant is expected sometime in the coming years, with the hope that the next attempt will succeed for the long term.

Music Has Given Him Something to Keep Reaching For

Despite the return of his cancer, Campbell has continued to work.

For the guitarist, that ability carries emotional weight.

He described being able to continue doing something he loves as “something to live for,” explaining that having a passion waiting for him gives him a reason to get up in the morning and look forward to the day.

That outlook is especially significant considering how long Campbell has been part of Def Leppard’s story.

He joined the British rock band in 1992 following the death of lead guitarist Steve Clark, who died in 1991 at age 31 from a combination of drugs and alcohol. Campbell went on to become a lasting member of the group alongside Joe Elliott, Rick Allen, Rick Savage and Phil Collen.

Over the decades, Def Leppard has remained associated with some of rock’s most familiar songs, including “Pour Some Sugar on Me,” “Love Bites” and “When Love & Hate Collide.”

And Campbell’s health battle has not brought the band’s work to a halt.

The group has 10 performance dates listed between Oct. 15 and Nov. 8, with stops including Florida, Mexico and Costa Rica, among other locations.

Def Leppard Is Still Looking Ahead

Campbell’s determination to keep working comes at a time when Def Leppard itself is actively preparing for another chapter.

The band’s most recent album, Diamond Star Halos, arrived in 2022, but new music is already on the way.

Singer Joe Elliott said the group is working toward another album expected in early 2027. The project will include “Rejoice,” a song released in February.

According to Elliott, work on the album continued even during the band’s Las Vegas residency in February.

On days away from performing, the musicians would head into a basement area of the casino that had been turned into a makeshift studio, where they continued recording parts of the project.

Elliott said the band was still recording and mixing the album, and he teased a wide range of material — including what he described as the fastest song Def Leppard has ever written, as well as an enormous, deliberately over-the-top track unlike anything the band has attempted before.

For Campbell, that ongoing creative activity gives his health story a striking contrast.

His cancer has returned. More treatment lies ahead. Another transplant is eventually expected.

But so do concerts, recording sessions and new music.

Campbell Has a Message for Others Facing Illness

Campbell’s experience has also changed the way he speaks about health.

Rather than focusing only on his own diagnosis, he encouraged others to pay attention to their bodies and take care of themselves.

For anyone who does receive a cancer diagnosis, his message centers on confronting the fear that can arrive with it.

“Life is for the living,” Campbell said, urging people not to allow fear to consume them after receiving devastating medical news.

His own experience has given that advice added meaning.

He has lived with a cancer diagnosis since 2013, experienced remission, faced a frightening deterioration years later, undergone a donor transplant and then learned that the procedure had not provided the lasting outcome he needed.

Now he is managing the return of the disease while preparing for the possibility of another transplant.

Through it all, Campbell continues to measure life not only by what his illness has taken from him, but by what remains.

For now, that includes his guitar, his bandmates, new music still being created and the chance to keep doing the work he loves.

The uncertainty has not disappeared. Neither has the cancer.

But Campbell is still looking toward the next stage.
