Uncle Liu is 66 years old, and the essence looks good, but he can be said to be an old smoker before. When he was young, he was addicted to smoking and smoking more than two packs every day. Two years ago, due to the continued non -alleviated cough, chest pain and other symptoms, they were admitted to the hospital. They were found to have a wide range of alternately large -bellied and double lung pneumonia. The lungs have long become dark.
The doctor said that Uncle Liu had only 20%of the lungs and had to work. If he wanted to continue to live, he had to perform lung transplantation. The hope of lung transplantation can only be kept in the donation of patients with brain death, and Mr. Liu can only face the consequences of waiting for the lungs.
The lung function continued to decline. In order to wait for the lung source, he couldn’t go out for half a year. He regretted it. Fortunately, after half a year, I waited for the right lung source and performed surgery in time!
1. How long will the lungs become black?
Do you know how high is the probability of lung cancer in a lifetime? According to the papers released by the British Cancer Magazine, the probability of those who have been smoking at 16%of lung cancer are 16%. People who smoke more than 5 cigarettes a day are 25%at the age of 75.
South Korea’s KBS TV has previously announced some images of the lung endoscopy, and found that the lungs of non -smoke absorbers are generally pale pink, and there may be some light black dots caused by air pollution.
The 15 -year -old lungs have large pieces of black spots; the lungs of 30 years of smoking are like splashing ink, and a lot of black substances have accumulated deep in the lungs.
According to data, 80%of lung cancer is related to smoking, and the lungs can generally be divided into three levels:
Level first: Black charcoal generally black lungs;
The second level: black net lungs, basically no pink, no flexibility like cumbers;
Third level: Like black sesame seeds, it feels a bit chronic, but it will have a grainy.
The degree of darkening of the lungs generally indicates the degree of lung disease. The degree of lung darkness of long -term smoking is generally the first or second level, especially those who smoke more than 20 daily, smoke within 20 years of age, and smoke age are more than 20 years old. The smokers are 13-25 times higher.
Frequent smoking, long -term contact with second -hand smoke, kitchen oil fume, car tail gas, decoration pollution and other people, the lungs are easier to turn black. Black lungs not only indicate lung health, but also endanger people’s lives.
Long -term smoking, harmful substances in tobacco smoke may stimulate respiratory cell mutations, induce lung cancer, and may cause other diseases such as cardiovascular and cerebrovascular diseases.
2. If the smokers start to quit smoking, what will happen to the body?
Do you know what changes your body will happen when you decide to quit smoking and no longer smoke? The Center for Disease Prevention and Control of the Chaoyang District of Beijing has issued a post to introduce the following changes that will happen after quitting smoking:
After three days of quit smoking:
In the blood, nicotine becomes less, the breathing starts to become smooth, and the sense of smell and taste is more sensitive.
After a month of quitting smoking:
A month later, the lung function improved a lot, coughing became less, and his spirit became better.
After three months of quitting smoking:
Symptoms such as shortness of breath, cough and other symptoms, better cardiopulmonary function, decreased infection rate, and smoother breathing.
After nine months of quitting smoking:
The probability of heart disease is half less than the smokers.
After three years of quit smoking:
Various functions of their bodies are restored, similar to their peers without smoking, and smoking has no temptation.
Five years of quitting smoking:
The teeth are no longer obviously black, and the chances of being followed by diseases such as lung cancer and laryngeal cancer have also reduced a lot.
In other words, although quitting smoking may have a quit reaction at first, if it can be survived and insisting on quitting smoking, it can effectively reduce the chance of cancer.
Many people may be curious. Can the dark lungs return to the previous color after quitting smoking? If you want to change back to healthy lung color, it is unlikely.
After all, the impact of harmful substances in tobacco tobacco on the lungs is irreversible. It is difficult for these harmful substances to be excreted, and the damaged lung function is difficult to recover. Therefore, it is not realistic to return to the previous color.
However, a study published in “Nature” pointed out that quitting smoking can make healthy lung cells proliferate and quit smoking at any time.
The researchers analyze the healthy airway cells of the current smokers, previous smokers, adults, and children. It is found that no matter which age group quit smoking, it will not only reduce the accumulation of damage, but also wake up some tobacco. Influential cells.
Third, why do some people get lung cancer after quit smoking?
Since no matter quitting smoking, why do some people get lung cancer after quit smoking?
If long -term smoking is diagnosed with lung cancer after quitting, it may actually be caused by the body of patients with long -term smoking harm.
Tobacco tobacco contains a variety of harmful chemicals, including more than 60 carcinogens. After entering the human body, these substances will slowly cause cell damage, activate cancer genes, and even induce physical cancer. After quitting smokers, lung cancer may be a manifestation of the accumulation of early smoking that causes damage to the body.
A study published in the “Internal Science Yearbook” found that lung cancer and smoking quitting can help extend the survival period.
Researchers have found that the medium time of the cigarette quit diagnosis is 22.8 months longer than those who continue to smoke. The overall mortality rate is relatively reduced by 33%, and the mortality rate caused by lung cancer has decreased by 25%.
However, in the process of quitting smoking, many people may encounter a “quit reaction”, thereby a series of discomfort. Those who are addicted to smoking are actually addicted to nicotine. When quitting smoking, nicotine in the body becomes less and dopamine secretes less, and people will have headaches, anxiety, depression, inattention, insomnia and irritability.
The quitting reaction of smoking quitting will not hurt the body.
Various symptoms that appear are a process that the body does not have nicotine, and this reaction is for a while, and most of them will disappear within 4 weeks after quitting. If you want to quit smoking, you must choose a scientific method. Once you decide to quit smoking, you must be fierce, formulate a plan to quit smoking, and also be good at summarizing experience.
Xiaojiu reminds everyone. At any time, quitting smoking is good for the body. Even if you have lung cancer, the survival period can be extended after quitting. Although quitting smoking will have an abstinence reaction, don’t worry, just go through.
