Is lung cancer contagious? Does it affect people around you?

Lung cancer itself is not an infectious disease and cannot be spread to others through contact, breathing or direct contact with the patient's body fluids. Lung cancer is a malignant tumor caused by the growth and spread of abnormal cells in the lung tissue. It is usually related to smoking, environmental pollution, genetic factors, etc. The condition of lung cancer patients may have a certain impact on the people around them.

1. Secondhand smoke: Smoking is the main risk factor for lung cancer. Long-term exposure to secondhand smoke will also increase the risk of lung cancer. If someone around you smokes, it will increase your own risk of lung cancer.

2. Family members: Genetic factors may play a role in some lung cancer patients. If there is a history of lung cancer in the family, immediate family members such as parents, brothers and sisters may have a higher risk of the disease.

3. Psychological and life burden on caregivers: The treatment process of lung cancer may cause psychological and life burden on the patient's caregivers. Caregivers need to take care of the patient, provide emotional support, and arrange daily life, which may have a certain impact on their physical and mental health.

In daily life, we need to develop good living habits, avoid smoking and exposure to secondhand smoke, maintain a healthy lifestyle, undergo regular physical examinations and lung cancer screening, and cooperate with doctors for treatment in a timely manner if any abnormal conditions occur.
