Will smoking for four years cause lung cancer?

Will I get lung cancer if I smoke for four years?

1. Smoking for four years does not necessarily get you lung cancer. People with good immunity may not get lung cancer, but people with poor immunity may get lung cancer.

2. Lung cancer is the most common primary malignant tumor of the lungs, originating from the bronchial mucosa or glands. The cause is still unclear, mainly including smoking, occupational exposure, air pollution, ionizing radiation, etc. The clinical symptoms of lung cancer are mostly hidden, mainly manifested as cough, weight loss, etc. Some patients will show blood in sputum, asthma, chest pain, etc. When you suspect that you have lung cancer, you need to go to the hospital in time. The doctor will conduct a careful physical examination of the patient, and then do chest X-rays and chest CT, tumor marker tests, pathological tissue biopsies and other examinations. After lung cancer is diagnosed, it can be treated with drugs such as erlotinib and gefitinib, or segmentectomy and wedge resection.

3. For people who have smoked for four years, whether they will get lung cancer depends on the specific situation. For people with good immunity, they may not get lung cancer. For people with poor immunity, their immune system will have problems and cannot identify and eliminate mutant cells in the body in time, so they may get lung cancer.
