Introduction

Advanced-stage lung cancer is not contagious. It is recommended to seek timely medical attention, identify the underlying cause, and undergo symptomatic treatment under the guidance of a qualified physician. Lung cancer is a malignant tumor originating from abnormal proliferation of cells in the lungs. This abnormal growth results from a combination of factors including genetic mutations, environmental influences, and lifestyle habits of the individual, rather than being caused by infectious pathogens.

In general, advanced-stage lung cancer is not contagious. It is recommended to seek timely medical attention, identify the underlying cause, and undergo symptomatic treatment under the guidance of a qualified physician. Here is a detailed explanation:

Lung cancer is a type of malignant tumor that originates from abnormal proliferation of lung cells. This abnormal cell growth results from a combination of factors, including the patient's genetic mutations, environmental influences, and lifestyle habits, rather than being caused by infectious pathogens. Therefore, lung cancer does not possess the characteristics of infectious diseases and cannot be transmitted from person to person through contact, droplets, blood, or other routes. The transmission of infectious diseases requires pathogens as intermediaries, but lung cancer does not involve such pathogens. Thus, whether in the early or advanced stages, lung cancer does not pose a transmission threat to people around the patient.

It is also important to maintain a healthy lifestyle, including quitting smoking, limiting alcohol consumption, eating a balanced diet, and engaging in appropriate physical activity, to help prevent the development of lung cancer.

Which internal organs can be damaged by smoking?

Smoking is extremely harmful to the human body and generally causes damage to the lungs, heart, liver, kidneys, and stomach. Harmful substances in tobacco smoke directly irritate the respiratory mucosa; long-term exposure can lead to chronic bronchitis, emphysema, and even lung cancer. Smoke also reduces pulmonary ventilation function, resulting in decreased respiratory efficiency and symptoms such as coughing and shortness of breath.

Can lung nodules cause back pain?

If a pulmonary nodule is relatively large in size (diameter exceeding 3 cm) or located close to the pleura, compressing or invading the pleura and surrounding nerve tissues, it may cause back pain. Some malignant nodules (such as early-stage lung cancer) can lead to radiating back pain when local invasion occurs. The pain is often described as dull or aching and may worsen with breathing or coughing, indicating a potential risk of disease progression that requires vigilance.
