Brad Arnold, lead vocalist of American rock band 3 Doors Down, revealed in a heartfelt Instagram post on Wednesday that he has been diagnosed with Stage 4 cancer, leading to the cancellation of the band’s upcoming summer tour. The 46-year-old shared the news in a video, explaining that what began as a routine hospital visit turned into something far more serious.

“I had been sick a couple of weeks ago and went to the hospital and got checked out, and actually got the diagnosis that I had clear cell renal carcinoma that had metastasized into my lung,” Arnold said. “It’s Stage 4, and that’s not real good.”

The band first broke into mainstream success in the early 2000s, propelled by the hit single “Kryptonite,” which climbed to No. 3 on the Billboard Hot 100. They were slated to tour this summer alongside rock heavyweights Creed, Nickelback, and Daughtry. Arnold expressed regret over having to cancel but emphasized that he’s facing the illness with conviction and deep faith.

“We serve a mighty God and he can overcome anything, so I have no fear,” he said. “I really, sincerely am not scared of it at all.”

The response from the rock community has been swift and emotional. Scott Stapp, frontman of Creed, commented on Arnold’s video, “If anyone has the FAITH and STRENGTH to face this fight, it’s YOU brother. You and your family are in my prayers daily.”

Support also poured in from the family of the late Charlie Daniels, who referred to Arnold as a “dear friend.” In their Instagram tribute, they praised his spiritual resilience and credited Daniels with playing a pivotal role in Arnold’s sobriety journey—something Arnold himself has called life-saving.

“Today he shared his cancer diagnosis with the world, and we want to lift Brad up in prayer for healing,” the Daniels family wrote. “The best part is that he’s done the most important healing already, and that is his spiritual healing and his faith in the power of Jesus.”

Arnold closed his message by referencing one of the band’s own anthems: “Now, I believe ‘ITS NOT MY TIME’ is really my song,” he wrote. “This’ll be a battle so we need our prayer warriors! Thank y’all for being the best fans in the world.”
