Can lung cancer be contracted all of a sudden?

1. Lung cancer is not usually contracted all at once.

2. Lung cancer is the most common primary malignant tumor of the lungs, originating from the bronchial mucosa or glands. The causes are usually related to smoking, occupational exposure, air pollution, ionizing radiation, dietary factors, physical activity, genetics and other factors. Patients often experience symptoms such as blood in sputum, irritating dry cough, asthma, chest pain, etc. Lung cancer does not form in a short period of time. Lung cancer is the result of multiple factors and long-term effects. Long-term damage to the lungs by harmful substances will stimulate the lung mucosal cells, leading to hyperplasia and malignant changes, and eventually forming lung cancer. Lung cancer generally cannot be cured all at once.

3. Lung cancer patients can obtain detailed information through physical examination, laboratory examination, imaging examination, pathological examination and other examination methods. After diagnosis, patients should actively cooperate with doctors for treatment. Drugs commonly used to treat lung cancer include erlotinib hydrochloride tablets and gefitinib tablets, which can be taken under the guidance of doctors and according to the doctor's advice. Lung cancer patients should also undergo bilateral lobectomy, bronchial sleeve lobectomy, pulmonary artery sleeve lobectomy and other surgeries according to their condition.

4. Patients should maintain a positive attitude, eat a balanced diet and promote recovery from the disease.
