Lung cancer: prevention and early detection

The world celebrates World Lung Cancer Day on August 1st to raise awareness about one of the most prevalent and deadly types of cancer, emphasizing the importance of prevention, early detection, and patient support. Despite advances in diagnostic methods and treatments, lung cancer remains the leading cause of cancer-related deaths globally, with nearly 2.6 million new cases recorded in 2024 and one-fifth of all cancer fatalities—approximately 1.9 million deaths. Smoking is the primary risk factor, responsible for the majority of cases, but exposure to secondhand smoke, air pollution, and carcinogens in the workplace also contribute. In its early stages, symptoms are often unclear but may include persistent cough, shortness of breath, pain, and coughing up blood. Early detection through imaging and prompt intervention—especially targeted therapies and immunotherapy—has improved survival rates. Campaigns focus on promoting smoking prevention, increasing early diagnosis, and improving treatments, with national efforts in the Kingdom to reduce associated risk factors.
