Michael Sweet, the lead singer of rock band Stryper, recently shared an update on his health status in a statement posted on Facebook. The announcement addressed concerns from fans and revealed details about his medical condition and upcoming treatment plans.
A biopsy performed on November 17 on a nodule in his right thyroid came back positive for malignant cells. Sweet confirmed the diagnosis as papillary thyroid cancer, noting that his doctor is optimistic about the prognosis given its slow-growing nature.
“A lot of you have been asking about my health and well being so I wanted to give you an update,” Sweet said. “First, thank you all for your continued thoughts and prayers. It always means the world and I can’t thank you enough for taking the time to think of me. I spoke to my endocrinologist and unfortunately the biopsy that was performed on 11/17 (a nodule in my right thyroid) came back positive. Malignant.”
Sweet outlined his medical timeline. He is scheduled for a CT scan and ultrasound on December 15, followed by a meeting with his doctor and surgeon on December 22 to plan the next steps. The band’s recording schedule for their new album will proceed as planned, beginning on December 28.
“I’m scheduled for a CT and an ultrasound next Monday 12/15 (following the Christmas show) and then I’ll be meeting with my doctor/surgeon on 12/22 to figure out a plan moving forward,” he continued. “We start recording the new Stryper album on 12/28 and that will remain on schedule. Once we finish tracking, I’ll be undergoing another surgery to remove my right thyroid and the nodule itself.”
Sweet addressed recent vocal performance issues by attributing them to the thyroid condition.
The singer said, “This is papilary thyroid cancer, so the good news that it’s slow growing and something that my doctor seems very optimistic about. Interestingly enough, I sang the album ‘When We Were Kings’ 2 months (to the day) after my first thyroidectomy, and I never felt better vocally. Unfortunately (and more recently), I’ve been experiencing a few issues vocally and it feels a little more ‘crowded’ in there. Now I understand why. My sincere apologies for not being to perform at 100% lately. It’s been a bit of a burden to be honest, but I’m confident that things will get better.”
He continued, “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. I’ll get in and deal with it and heal up and be ready for 2026. Please don’t worry about me as I know and trust that God has a plan.”
He expressed confidence in his recovery and thanked fans for their ongoing support and prayers, and added, “I’ve always felt some kind of peace in being able to ask for prayer here. Whether it’s for someone else or for myself, you always take the time to do that and it is a true blessing. It’s been a constant in my life and I believe that you all are friends. Family. I love you guys and I can’t wait to see you on the road in 2026. Merry Christmas and I hope you all are enjoying the new Stryper Christmas Album! Always remember – He Is The Reason For The Season.”
Papillary thyroid cancer is the most common type of thyroid cancer, according to Blabbermouth. This aligns with Sweet’s optimistic outlook regarding his diagnosis. The 62-year-old singer’s determination to continue with the band’s recording schedule demonstrates his commitment to Stryper despite the challenging health circumstances he is facing.
Sweet’s thyroid issues are not entirely new. The frontman underwent partial thyroid surgery in December 2023 to remove nodules on the left side of his thyroid, as reported by Ultimate Classic Rock. A cystic nodule remained on the right side that was monitored until it was biopsied and diagnosed as cancerous in 2025. This history provides important context for understanding the progression of his condition.
“This is papilary thyroid cancer, so the good news that it’s slow growing and something that my doctor seems very optimistic about,” Sweet stated in his message. “My sincere apologies for not being to perform at 100% lately. It’s been a bit of a burden to be honest, but I’m confident that things will get better.”
Sweet has asked fans for prayer as he prepares for surgery and continues recording new music, Parade reported. This demonstrates his resilience and faith during this difficult period. The singer expressed confidence in recovery and indicated he looks forward to touring in 2026, showing his determination to overcome this health challenge and return to performing at full capacity for his devoted fanbase.
