Lung cancer is often called the silent killer. By the time symptoms appear, the disease has usually advanced, making treatment more difficult and survival chances lower. For decades, doctors have searched for a way to identify risk before cancer takes hold. Now, scientists may have found one. A groundbreaking study has revealed a blood-based protein signature capable of predicting lung cancer risk more than five years before diagnosis. It is a discovery that could change the future of cancer prevention and early intervention.
