Michael Sweet, the frontman of Stryper, has announced that he has been diagnosed with cancer.

In a post shared on Facebook, the 62-year-old singer mentioned that a “biopsy that was performed on 11/17 (a nodule in my right thyroid) came back positive. Malignant.”

“I’m scheduled for a CT and an ultrasound next Monday 12/15,” he continued, “and then I’ll be meeting with my doctor/surgeon on 12/22 to figure out a plan moving forward.”

Sweet further revealed that he was diagnosed with “papillary thyroid cancer,” adding that “the good news (is) that it’s slow growing and something that my doctor seems very optimistic about.”

The rocker admitted he’s recently been “experiencing a few issues vocally and it feels a little more ‘crowded’ in there. Now I understand why.” He apologized to fans for performing at less than 100%, but expressed confidence that things will improve.

“Even though it’s concerning to even hear the ‘C’ word (much less be diagnosed with it), I believe that it will be behind me soon enough,” Sweet stated. “I’ll get in and deal with it and heal up and be ready for 2026.”

In another part of his message, Sweet disclosed that despite his cancer diagnosis, Stryper is still on track to begin recording their new album on Dec. 28.

“Once we finish tracking, I’ll be undergoing another surgery to remove my right thyroid and the nodule itself,” the singer noted. He expressed gratitude to fans for their ongoing support and prayers, adding that he looks forward to returning to touring. “I love you guys and I can’t wait to see you on the road in 2026.”

Stryper’s 16th studio album, When We Were Kings, was released in 2024. The band’s next performance is scheduled for April 12, 2026, on the Monsters of Rock Cruise.
