What is stage 4 clear cell renal cell carcinoma?
In adults, clear cell renal cell carcinoma (RCC) is the most prevalent form of kidney cancer. As the disease advances, it can spread beyond the kidneys to other organs, as it did in Arnold's case.
In May 2025, when Arnold announced that the stage 4 kidney cancer had spread to his lungs, he said, “That’s not real good. But you know what? We serve a mighty God, and he can overcome anything. So I have no fear. I really, sincerely am not scared of it at all.”
Clear cell renal cell carcinoma often shows no symptoms in early stages. The disease is only diagnosed when there is a screening for other health conditions.
When symptoms do appear, they may include blood in urine, lower back pain, fatigue and unexplained weight loss.
Stage 4 kidney cancer occurs when cancer cells spread beyond the fatty tissue surrounding the kidney to the adrenal glands, nearby lymph nodes, or distant organs. While treatment options may be available, the 5-year survival rate for stage 4 renal cancer remains low at 10%.

“His music reverberated far beyond the stage”
3 Doors Down's social media post shared a heartfelt message in the announcement post of his passing. The band wrote, “As a founding member, vocalist, and original drummer of 3 Doors Down, Brad helped redefine mainstream rock music, blending post-grunge accessibility with emotionally direct songwriting and lyrical themes that resonated with everyday listeners.”
They further praised his music and stage presence. “His music reverberated far beyond the stage, creating moments of connection, joy, faith, and shared experiences that will live on long after the stages he performed on,” the post read.
In May 2025, Arnold had asked his fans to pray, saying, “Lift me up in prayer every chance you get” by listening to 3 Doors Down’s 2008 song ‘It’s Not My Time.’”
