Major breakthrough alert: a new trial found that the immunotherapy drug pembrolizumab (Keytruda) kept head and neck cancer away for FIVE years—double what standard treatments do! Not only did it slash the risk of cancer coming back somewhere else, but it also worked for all patients, not just those with certain immune markers. After 20+ years of the same old treatments, this could be a total game-changer for thousands facing head and neck cancer. #CancerBreakthrough #Immunotherapy #Keytruda #Health
