Lung cancer is the leading cause of cancer-related deaths worldwide, characterized by its aggressive nature and very poor prognosis. It often remains undetected until advanced stages, which is why there is increasing effort to develop screening programs for the early detection of lung cancer. The typical clinical presentation of a lung cancer patient includes cough, shortness of breath, chest pain, and haemoptysis. Treatment options, including surgery, chemotherapy, radiation, and immunotherapy, have advanced significantly over the past few decades. However, treating lung cancer remains a serious challenge, especially in emergencies that it can cause. There are three groups of emergencies in lung cancer: paraneoplastic syndromes, structural complications, and treatment complications. Each of these emergencies requires a multidisciplinary approach involving oncologists, pulmonologists, radiologists, emergency medicine specialists, and thoracic surgeons. Technological and medical advances have led to the development of new imaging techniques and new targeted therapies, significantly improving the quality of care for these emergencies. By focusing on preventive care, leveraging technological advances, and fostering collaboration among healthcare professionals, the medical community can better address the urgent challenges posed by these emergencies. Such a comprehensive strategy is crucial for improving outcomes, extending survival, and enhancing the quality of life for patients.
