45 -year -old Uncle Wang is the middle management of a company. The normal work pressure is very high. In addition, the familys livelihood problem points to him, causing him not to relax.In order to relax himself appropriately, he learned to smoke.In the past two years, the amount of smoking is very large. When the project is rushing, it will even absorb 2 packs in a day.
About half a year ago, he frequently had cough symptoms on his body, and sometimes he had obvious chest tightness.When I went to the hospital, I found that there was a 8mm grinding glass nodule in the lungs. The pathological results after surgery were displayed as .After the operation, the doctor suggested that he consolidate several chemotherapy to prevent the cancer cells of "leakage fish".In this regard, Uncle Wang was anxious. He was afraid of falling down. What can the family do?I knew so early, and I didnt smoke at that time.But now, everything is too late.
One or 100 smokers, how many people do they have lung cancer in the end?
Many people are like Uncle Wang, and they can regret it after diagnosis of lung cancer.However, some people are incredible after diagnosis of lung cancer: "How can smoking get lung cancer?"
The reason why they have such a misunderstanding is mostly because of a rumor on the Internet before: Many old smokers are safe and sound, indicating that severe smoking is not easy to suffer from lung cancer.
Heavy smoking is not easy to get lung cancer, true or false?
Professor Xiao Dan, director of the control of smoking and respiratory disease prevention and control department of the China-Japan Friendship Hospital.
This statement on the Internet comes from a widely circulated research.Its research objects are only 31 adults, including 12 non -smokers and 19 smokers.Investigators found that 14 smokers suffered from lung cancer and only one of those who did not smoke suffered from lung cancer.Further investigation found that with the increase of smoking, the DNA mutation will not increase significantly at 23 packs of years.
But DNA mutation is just one of the reasons for lung cancer. The mutation no longer increases does not mean that it will not suffer from lung cancer.And research does not further provide relevant support data. Whether it is reliable is really required for more research and proof, not credible.Moreover, smoking will cause the risk of lung cancer to increase significantly, and as the amount of smoking and smoking period increases, the risk will further increase, which is beyond doubt.
So is there any relationship between smoking and lung cancer?
A study in British Cancer Magazine may be inspired by many people.The study analyzed the number of male lung cancer cases in multi -centered male lung cancer from 1985 to 1994, and counted the cumulative risk of lung cancer of 75 -year -old men.
结果发现，75岁时从不吸烟者的肺癌累计风险为0.2~0.6%、戒烟者为4.2~6.5%、持续吸烟者为14~16%，每The risk of daily smoking & gt; 5 continuous heavy smokers is 20 ~ 25%.In other words, every 100 smokers will die of lung cancer before the age of 75, and the number of severe smokers will increase to 25.It can be seen from this data that the number of patients with lung cancer in smokers is indeed a lot.
2. In addition to lung cancer, smoking is also related to these diseases
Tobacco is one of the social issues that seriously threaten public health, and smokers not only threaten their own health, but also the risk of lung cancer in human lung cancer for a long time will increase.In addition to lung cancer, long -term smoking is also easy to induce various diseases.
1. Oral health
The University of Birmingham and German Human Nutrition Study conducted a researchResearchers analyzed 23,000 subjects and evaluated the correlation between smokers, smoking quitters and teeth of the three ages.It was found that smoking was obviously correlated with the teeth, and it was more obvious in middle -aged and elderly people.Compared with non -smokers, the risk of teeth falling from male and female smokers will increase by 3.6 times and 2.5 times respectively.
2. Cancer
Chief physician Zheng Ronghui pointed out that smoking can stimulate normal cells to cause abnormal proliferation. After a long time, it is easy to cause cancer.And smoking can cause DNA damage. If long -term damage is not repaired in time, it will cause DNA mutations and lacks to induce cancer.
3. Myocardial infarction
Chen Zhongwu, chief physician of the Department of Cardiovascular Department of the Peoples Hospital of Yuhuan City, said that smoking isOne of the main incentives to induce myocardial infarction.Because there are nicotine and carbon dioxide components in tobacco, these two substances will increase blood viscosity and slower blood flow, which will easily lead to thrombosis and increase the risk of coronary arteries.In addition, smoking can also cause vascular endothelial injuries, increase the risk of plaques, and have a direct correlation with the occurrence of myocardial infarction.
4. Respiratory disease
The respiratory immune system, lung structure and function have impact.Long-term smoking will increase the risk of , chronic bronchitis, tuberculosis and other respiratory diseases.
3. Reminder: These 4 cigarettes have been included in the blacklist
Smoking is harmful to health. ThisEveryone knows the words, and even clearly commented in the packaging of each bag of cigarettes.Smoking is not good, smoking is not good.Especially these cigarettes, be careful!
1. Fine rod smoke
Experts from Shenyang Health Education Center have conducted a study,Burning fine rod smoke and coarse cigarettes in the same room, then measured the PM2.5 concentration of the indoor. It was found that the tobacco smoke concentration released by fine rod smoke was slightly higher than that of thick rod smoke.A Dutch epidemic survey also shows that the use of fine rod smoke on cancer is greater than coarse cigarettes.
2. Electronic cigarette
, Acetaldehyde and other cymbals, in which formaldehyde has a strong carcinogenic effect, which will cause great damage to the respiratory tract.And as the temperature rises, the concentration of formaldehyde and acetaldehyde will increase significantly.There are also researchers who detect the unique nitrosamine components of tobacco in the electronic smoke liquid, which is also a clear type of carcinogen.
3. Miscellaneous smoke
Miscellaneous cigarettes are usually cheap.However, they have not undergone rigorous quality inspection, and the harmful substance content inside will be much higher than that of regular cigarettes. The damage caused by this type of cigarettes to health is inestimable.
4. Belly smoke
Refers to a cigarette with a liquid bead in the tobacco filter, which is wrapped in different types of spices inside, which can improve the smell of smoke after pinching.The Tianjin Disease Prevention and Prevention Center pointed out that beaded smoke is more harmful than ordinary cigarettes.The fragrance spices in the burst do not have complete industry specifications and safety certifications, and there may be food safety problems.And the improvement of smoke will be more acceptable after the improvement of the smell of smoke, it is easy to increase the amount of cigarettes, which will cause more harm to health.
Smoking is harmful to health. This is beyond doubt. People who are still smoking quit smoking as soon as possible to think about the health of themselves and their families.
