Lung cancer and emergency department. ED providers may encounter lung cancer along the cancer continuum. The ED may play a role in identifying those at risk of developing lung cancer or referring for further screening those with concerning findings. Incidental lung cancer may present with or without symptoms, and appropriate staging and tissue diagnosis with molecular markers are crucial. Sequelae from active treatment may include pain, radiation-induced lung injury, or drug-related pneumonitis. In those with advanced or metastatic disease, stabilization, symptom management, and supportive care are often required
