How much do you know about the harm of smoking

I believe everyone knows something about the harm of smoking, but many people just can't quit smoking. The reason is very simple: they have become addicted to smoking. So what should they do in this situation? Below we will introduce some specific harms of smoking.

Smoking causes lung cancer. 90% of total mortality is caused by smoking. A person who smokes ten cigarettes a day has ten times the risk of developing the disease as a non-smoker. Damaged cells cannot return to normal. The early stages of the disease may go undetected until the cancerous cells spread to the blood vessels and other organs. (So ​​far, lung cancer is the most deadly cancer in the world, and it is almost impossible to detect it in its early stages. The survival rate of patients diagnosed with lung cancer is less than 5% after 3 years, and almost zero after 5 years.

Doctors recommend that smokers should have a chest X-ray every 3 to 6 months. If they experience symptoms such as dry cough, blood in sputum, chest pain, and fever, they must not take it lightly and should go to the hospital immediately for a sputum exfoliated cell examination. Only in this way can the possibility of early detection of lung cancer be increased. ) Smoking can also cause emphysema. The toxic substances accumulated in the bronchi of the lungs will hinder the normal exhalation of the air inhaled by the human body, causing the lung cells to swell or burst, resulting in difficulty breathing for the patient. Patients with severe emphysema are in great pain. In order to breathe in enough oxygen, they have to stand upright and breathe at a high frequency. Even on flat ground, they have to walk slowly. Some more seriously ill patients have to rely on oxygen bags to sustain their lives. They must concentrate all their efforts on doing a simple action - breathing - for the rest of their lives.

Smoking is the main risk factor for chronic obstructive bronchitis. Because smoking can cause the cilia of bronchial epithelial cells to become shorter and irregular, as well as movement disorders, reducing local resistance and making it easier to get infected.

So many times we know what the dangers are, but we just can't quit. This is actually a very serious problem. When you really have problems in the future, it will be too late to regret it. So you should be responsible for your health while you still have a chance, otherwise you will regret it for the rest of your life.
