Researchers just found a genetic clue that could help doctors predict which brain cancer patients will actually benefit from the drug bevacizumab. Basically, if your tumor has a certain genetic change (CDK4 amplification), you might get way more out of this treatment. This could mean fewer people getting unnecessary side effects and more targeted care for those who need it most. Personalized medicine is seriously leveling up! #Health #BodyHealth #CancerResearch
