May 31st is World No Tobacco Day, and this year marks the 35th World No Tobacco Day.
Everyone must have known that “smoking is harmful to health” for a long time.
However, this unhealthy behavior has not been eliminated so far. More ironically, the proportion of people suffering from smoking, the rate of young people trying to smoke, and the current smoking rate are increasing year by year.
Too hard to quit smoking? Check out the disease risks associated with smoking
Be aware that tobacco smoke contains more than 7,000 chemicals, hundreds of which are harmful when you’re driving At least 69 are carcinogens, such as benzopyrene, nicotine and formaldehyde.
In addition, if you smoke for a long time, it is easy to induce the appearance of three types of cancer. The mortality rate of these three types of cancer is very high, which will bring great threat to the health and life of patients.
Which three types of cancers are more likely to be caused by smoking?
First, lung cancer
The morbidity and mortality of lung cancer ranks first among all malignant tumors. Malignant tumors of the bronchial mucosa.
The main cause of lung cancer is smoking, and smokers are 20 times more likely to develop lung cancer than non-smokers.
And the longer the smoking age and the more smoking, the higher the risk of developing lung cancer, and the mortality rate after the disease is about 10 times higher than that of non-smokers.
When these carcinogens in tobacco stimulate the bronchial mucosa of the human body for a long time, it will cause the mucosal metabolism disorder, which will lead to the formation of DNA changes that lead to the appearance of cancer.
Second, oral cancer
The main cause of upper oral cancer is related to prolonged smoking.
The oral mucosa of people who smoke for a long time will have different degrees of inflammatory hyperplasia. Most of the smokers will have some hyperplasia and whitening on the oral mucosa. This phenomenon is called Leukoplakia is a precancerous phenomenon of oral cancer.
When smoking, the toxic chemicals in the smoke will stimulate the oral mucosa, and it is easy to cause some inflammatory lesions in the oral mucosa.
In addition, due to the stimulation of smoke, the local oxygen tension in the oral cavity is greatly reduced, which makes some bacteria grow in the oral cavity. Over time, it is easy to damage the mucous membrane excessively, thereby causing the appearance of oral cancer.
Third, esophageal cancer
esophagus Cancer, also known as esophageal cancer, is a malignant tumor that occurs in the esophagus, and its morbidity and mortality are increasing year by year.
The causes of esophageal cancer are related to improper diet and smoking.
When smoking, the harmful components such as tar, epoxide, dimethylnitrosamine, nicotine and so on in the smoke will cause some chronic irritation to the esophagus, causing damage to the cells in the esophagus. cause cancer.
In addition to the above three cancers, smoking can easily induce pancreatic cancer and bladder cancer in men. For women, long-term smoking can easily induce gynecological cancers such as ovarian cancer, breast cancer.
At the same time, long-term heavy smoking can lead to blood pressure increase and heart beating faster, which can easily lead to various heart diseases. It also affects the body’s absorption of calcium, resulting in osteoporosis.
Secondhand smoke harms innocent victims even more p>
For decades, tens of thousands of scientific studies have proved that secondhand smoke exposure can seriously harm the health of people.
Secondhand smoke can lead to diseases such as cancer, cardiovascular disease, and respiratory disease, leading to a 25-30% increased risk of coronary heart disease and a 20-30% increased risk of lung cancer in smokers.
For newborns, secondhand smoke can also cause neonatal-induced syndrome, otitis media, and low birth weight.
At the same time, because secondhand smoke contains various compounds that can rapidly stimulate or damage the lining of the respiratory tract, even brief exposure can cause damage to the upper respiratory tract and trigger frequent asthma attacks.
This also explains a lot—If one person smokes, the whole family suffers!
But the problem is that many people have not really realized that although smokers have the right to actively choose to smoke, they should not cause the harm of passive smoking.
And the environment around us is currently also There is no public opinion pressure against the harm of passive smoking.
Therefore, I advise all friends, please say no to smokers!
Why do you need to give others’ health at the expense of your own health? What about evil deeds?
