When it comes to cancer drug treatments, one size doesn't fit all. That's because our unique genetics determine how our body reacts to certain drugs, which can turn a life-saving treatment into a side-effect nightmare. This is the problem Dr. Richard Kim has spent his career solving. He's championed pharmacogenomics: using genetics to match the right drug to the right patient. His persistence helped make Ontario one of the first provinces to adopt genetic testing that prevents severe chemotherapy side effects, saving lives and reshaping cancer care. In this episode, Dr. Kim explains why "one-size-fits-all" medicine is outdated and how innovations in technology are turbocharging genomics and precision medicine. With Richard B.
