Campbell's Battle with Lymphoma

Campbell's battle with Hodgkin lymphoma began in 2013 when he noticed persistent symptoms. He described it as “the cough that wouldn’t quit,” which eventually led to his diagnosis. Through rigorous chemotherapy, Campbell managed to achieve remission, though the road was not without challenges. In November 2013, he shared on Facebook, “I’m officially in remission from Hodgies.” Despite this victory, he remained cautious, knowing the disease could return.In June 2015, Campbell revealed the recurrence of his lymphoma. This time, he opted for immunotherapy, specifically a drug called pembrolizumab. “For the bulk of those 10 years, I actually was doing immunotherapy,” he explained during a 2023 episode of the Lymphoma Voices podcast. “Starting in June of 2015, I started taking pembrolizumab. It worked well for me, and I’ve been able to live my life.”

A Legacy of Dedication and Perseverance

Throughout his career, Campbell has remained dedicated to his craft, balancing his passion for music with his health. His resilience has inspired countless fans and fellow musicians. Campbell's approach to his illness reflects a philosophy of acceptance and perseverance. “It’s sort of like Whac-a-Mole,” he remarked. “You beat something back, and then it pops up somewhere else. But it hasn’t been too difficult for me. I deal with it fine.”The band's decision to continue touring, even in the face of adversity, underscores their commitment to their fans.
