For over two decades, Brad Arnold’s voice — gravelly, emotive, and unmistakable — has been at the center of some of rock music’s most enduring anthems.

As the frontman of 3 Doors Down, his songs became fixtures on radio and in fans’ lives, with hits like “Kryptonite,” “Here Without You,” and “It’s Not My Time”.

Giving voice to themes of vulnerability, perseverance, love, and resilience. Yet in 2025, the very themes he explored in his lyrics became alive in a new and deeply personal chapter of his life.

In a heartfelt announcement shared with fans, Arnold revealed that he has been diagnosed with stage 4 clear cell renal carcinoma, a form of kidney cancer that has metastasized — meaning the disease has spread — to his lungs.

Along with the news came the difficult decision: 3 Doors Down would cancel their summer 2025 tour, including dozens of planned performances across the United States.
