Infectious diseases typically require three conditions: a source of infection, a transmission route, and a susceptible population. However, lung cancer is not contagious and generally does not spread to others through any route, whether in the early or advanced stages.

Patients with advanced lung cancer may experience symptoms such as weight loss, hemoptysis (coughing up blood), chest pain, hoarseness, and difficulty swallowing. These symptoms are primarily caused by tumor growth, spread, or metastasis.

To ensure the patient's health and safety, appropriate preventive measures should still be taken, such as avoiding sharing personal items and maintaining good hygiene habits.
