WATCH: New lung cancer discovery may aid prevention

Article excerpt

Researchers have identified a mechanism that could help doctors predict and prevent lung cancer, the world's deadliest malignancy. The discovery, explained by ABC News medical correspondent Dr. Tara Narula, offers a potential path toward earlier intervention and prevention strategies. The finding addresses a major public health challenge, as lung cancer kills hundreds of thousands annually worldwide. By understanding how the disease develops at a cellular level, physicians may be able to identify at-risk patients before tumors form. The research suggests preventive approaches could complement or even substitute for treating advanced cases.
