Smoking is a bad habit that is hard to quit not only in men but also in women. Cigarette smoke has a significant impact on health, especially the lungs. Can cause lung diseases such as chronic obstructive pulmonary disease, pneumonia, especially lung cancer.

Tobacco smoke contains many harmful substances that can damage the respiratory system.
These toxic substances are chemicals that, when inhaled directly into the lungs, will lead to an overproduction of mucus in the lungs along with a lower ability to excrete mucus out of the body than the average person. Therefore, the bronchial mucosa of smokers for many years has changed in structure, proliferating mucous glands, thickening the lining of the airways, increasing sputum secretion, causing narrowing of the airways. In addition, the lungs are not able to clear excess mucus effectively, which will be favorable conditions for respiratory infections. Manifested by cough, bronchitis and infections such as pneumonia, obstructive pulmonary disease, lung cancer,... The lungs of a long-time smoker can turn black, while in a healthy person ruddy. At the same time, the part that can't pump as full of air as a non-smoker because the smoke makes the lungs hard, reduces elasticity, and affects lung function. In addition, the harmful effects of tobacco also cause:
90% of cases diagnosed with lung cancer are tobacco users. Tobacco is also the cause of 75% of cases of chronic obstructive pulmonary disease. increase the risk of dying from the disease 66 times compared to non-smokers. Secondhand smoke increases the risk of bronchitis, pneumonia, tuberculosis, and asthma in adults. In children, secondhand smoke increases the risk of respiratory symptoms such as coughing, wheezing, shortness of breath, slows lung growth, and causes premature decline in lung function. Tobacco not only affects direct smokers, but passive smokers are just as vulnerable as direct users.

Normally, the lungs of normal healthy people will be ruddy, with no abnormal signs.
For smokers, images of the lungs on characteristic x-ray films. However, each person is not the same, because smoking time is different smoking dose, so the impact of tobacco on the lungs is different. But basically the symptoms are the same, just different in degree.
The chest x-ray image of a smoker shows:
The outside of the lung is covered with a black membrane. The longer a smoker has smoked, the more obvious this black film becomes. Lungs may increase in size than normal, many black dots are inflammatory sites... Alveolar dilatation can be seen on X-ray, showing barrel-shaped lungs, dilated intercostal spaces, and regions. Brightening corresponds to areas of alveolar dilatation. Chest X-ray can suspect chronic obstructive pulmonary disease to help detect the causes of exacerbations: Pneumonia, pneumothorax, signs of pulmonary embolism... In Vietnam, lung cancer is The disease ranks first among the 10 most common cancers in both men and women. The leading cause of lung cancer is the habit of smoking. In order to reverse lung cancer and other dangerous cancers caused by tobacco in the community, Vinmec International General Hospital offers a Lung Cancer Screening Package to help detect lung cancer early, reduce mortality. death from lung cancer.

The hospital is home to a team of experienced experts, combined with the world's leading modern equipment system, autologous immune-boosting therapy, biopsies, and diagnostic techniques. Imaging diagnostics such as computed tomography (CT-Scanner), magnetic resonance imaging (MRI),... help diagnose and treat diseases more accurately.
