Introduction
Under normal circumstances, lung cancer is not contagious. If you experience any discomfort, it is recommended to seek timely medical examination. A detailed explanation is as follows: lung cancer is a disease that develops when lung cells are damaged and become malignant. Its occurrence is mainly related to genetic mutations, hereditary factors, and environmental factors, rather than pathogenic microorganisms; therefore, it is not contagious. Even close contact with a lung cancer patient does not pose a risk of transmission.
Generally, lung cancer is not contagious. If you experience any discomfort, it is recommended to seek medical attention promptly for examination. Detailed explanation is as follows:
Lung cancer is a disease that develops when lung cells are damaged and become malignant. Its occurrence is mainly related to genetic mutations, hereditary factors, and environmental factors, rather than pathogenic microorganisms. Therefore, it is not contagious. Even with close contact with a lung cancer patient, one will not develop lung cancer from exposure to cancer cells. However, lung cancer does demonstrate a certain degree of familial clustering, which is primarily the result of combined genetic and environmental factors, rather than transmission. Individuals with a family history of lung cancer may have a relatively higher risk of developing the disease, but this does not imply that lung cancer can spread among family members or be transmitted from person to person through daily contact, air, food, or other routes.
In daily life, one should avoid smoking and reduce air pollution to protect both personal and others' health.
