Michael Bolton, the hugely popular ballad singer who rose to peak fame in the late 1980s and early 1990s, announced Wednesday that he has incurable brain cancer but hopes his situation can inspire others. Bolton’s news first was reported by People. He was diagnosed with glioblastoma in December 2023 after emergency surgery and had another surgery in January 2024. He tells People he ended chemotherapy and radiation treatments in October. “My hope in sharing this part of my journey is that it might offer comfort to other families facing similar challenges, and perhaps even inspire those navigating their own adversity,” Bolton, 72, says in a post on social media. “I want to take a moment to thank the incredible team who helped me tell this story, and who turned what could have been a very difficult day into something truly meaningful, and even joyful, for me and my family.” According to the Mayo Clinic, glioblastoma is an aggressive cancer that starts in the brain or spinal cord. Its symptoms include “headaches that keep getting worse, nausea and vomiting, blurred or double vision, trouble speaking, altered sense of touch, and seizures. There also may be trouble with balance, coordination, and moving parts of the face or body.” Bolton’s daughters tell People they knew something was wrong with their father when he showed unusual behavior during a bowling outing in the fall of 2023. They Bolton repeatedly tried to bowl out of turn and he fell out of his chair. Later that same weekend he complained of bad headaches. It was just days later that he had emergency surgery to remove a tumor, People reports. “Everything that happened was weird for him but not super alarming,” his daughter Taryn, 45, tells People. “When you look back at everything together … We missed so many things.” Bolton says his most recent scan in April showed his brain was clear of a tumor. However, the cancer has a 90% recurrence rate and the average length of survival for people with glioblastoma is about eight months, USA Today reports. He lives in Westport, Conn., and tells People that he meditates daily and plays plenty of golf. He also works with a personal trainer and takes voice lessons. “I also want to thank all of you for the love, support, and patience you’ve shown over this past year,” he says in his social media post. “I’ve drawn strength from your encouragement, and I continue to draw strength from it every day as I move forward on this journey.”
