3 Doors Down singer Brad Arnold announced he was diagnosed with Stage 4 kidney cancer in a video posted on the band’s social media accounts on Wednesday.

“Hey, everybody, it’s Brad from 3 Doors Down. I hope you’re having a great day today,” the “Kryptonite” singer said in the video. “I’ve got some not-so-good news for you today. So I’d been sick a couple of weeks ago and then went to the hospital and got checked out and had actually got the diagnosis that I had clear cell renal [cell] carcinoma that had metastasized into my lung. And it’s Stage 4, and that’s not real good.”

Clear cell renal carcinoma is the most common type of kidney cancer, according to the National Cancer Institute. However, it has about a 10% 5-year survival rate after it spreads to other parts of the body.

Arnold said the band was canceling its upcoming tour with Creed due to the diagnosis. However, the frontman said he remained hopeful.

“You know what? We serve a mighty God, and he can overcome anything,” Arnold said in the video. “So I have no fear. I really, sincerely am not scared of it at all. But it is gonna force us to cancel our tour this summer. And we’re sorry for that. And I’d love for you to lift me up in prayer every chance you get. And I think it’s time for me to maybe go listen to [3 Doors Down’s song] ‘It’s Not My Time’ a little bit. Thank you guys so much. God loves you, we love you. See ya.”

3 Doors Down formed in Mississippi in the late 1990s and broke through with 2000’s “The Better Life,” which went seven-times platinum on the back of hits like “Kryptonite” and “Loser.”
