My chest feels stuffy and sometimes hurts. I smoke a lot. I don't know if it's lung cancer

Chest tightness, pain, and heavy smoking may be caused by bad living habits, or by diseases such as bronchitis and pneumonia. However, the possibility of lung cancer cannot be ruled out.

1. Physiological factors

1. Bad living habits: If you smoke for a long time or smoke a lot, it may cause certain damage to the lungs, resulting in the above symptoms. It is recommended that patients quit smoking in time, maintain a good living environment, and avoid inhaling secondhand smoke.

2. Pathological factors

1. Bronchitis: It is usually an inflammatory disease of the upper respiratory tract caused by bacterial infection. During the onset of the disease, symptoms such as coughing and sputum usually occur. If it is not effectively treated, it may even be accompanied by chest tightness. You can take amoxicillin capsules, cefixime capsules and other drugs for anti-inflammatory treatment as prescribed by the doctor.

2. Pneumonia: It is usually caused by the invasion of Staphylococcus aureus when the body's resistance is reduced. After the onset of the disease, the patient is prone to symptoms such as fever and shortness of breath. As the disease progresses, it may also affect normal life and work. At this time, it can be treated by atomization inhalation, such as using terbutaline sulfate suspension, ipratropium bromide aerosol, etc.

3. Lung cancer: It is a malignant tumor disease. The cause of the disease is related to factors such as genetics and air pollution. After the disease occurs, the patient will experience symptoms such as coughing, coughing up blood, and chest pain. At this time, combined treatment such as chemotherapy and radiotherapy can be carried out under the guidance of a doctor.

In addition, it may also be caused by reasons such as coronary atherosclerotic heart disease. It is recommended to go to the cardiovascular department of a regular hospital in time and actively cooperate with the doctor's treatment.
