Spotlighted in MrBeast's latest YouTube video, St. Baldrick's is joining Stand Up To Cancer, MrBeast, and Beast Philanthropy to help make the next SU2C Pediatric Cancer Dream Team possible.
Matthew Luka Mackriel became terribly ill, and at first, doctors said it was iron deficiency, but weeks later on the 14th of June 2026, he was diagnosed with a rare cancer called acute promyelocytic luekemia (APL).
Only 4 days later, before little Matthew could even start his chemo therapy, he sadly suffered a seizure, he was rushed into emergency surgery to control a massive bleed on the brain, but sadly little Matthew succumbed while he was in surgery.
We are now faced with huge a huge amount of debt for the past few months Matthew had to be admitted into hospital.
