How long do you smoke before your lungs turn black?
Do you know how high the risk of lung cancer is for a lifetime smoker? Those who smoked consistently had a 16% chance of dying from lung cancer, and those who smoked more than five cigarettes a day had a 25% chance of dying by the age of 75, according to data published in the British Journal of Cancer.
South Korean broadcaster KBS had previously released images of lung endoscopes that found non-smokers’ lungs, which are typically pale pink, may have light black spots caused by air pollution.
After 15 years of smoking, the lungs have large black spots. After smoking for 30 years, black matter accumulates deep inside the lungs.
According to statistics, 80% of lung cancer is related to smoking, and the darkening of the lungs can be generally divided into three grades:
First level: black charcoal general black lung;
The second stage: black lung, almost no pink, as inelastic as cinder;
Level 3: Like sprinkled with black sesame seeds, it feels a little chronic, but it will have a grainy feeling.
The degree of blackening in the lungs generally predicts the extent of lung disease. The lung black degree of long-term smokers is generally grade I or Grade II, especially those who smoke more than 20 cigarettes a day, those who start smoking within the age of 20, and those who smoke for more than 20 years, the chance of developing lung cancer is 13-25 times higher than that of non-smokers.
Regular smoking, long-term exposure to second-hand smoke, kitchen fumes, vehicle exhaust, decoration pollution and other people, the lungs are more likely to become black. Black lung not only indicates the health of the lungs, but also may endanger people’s lives.
Long-term smoking and harmful substances in tobacco smoke may stimulate mutations in respiratory cells, induce lung cancer, and may also cause cardiovascular and cerebrovascular diseases and other diseases.
What happens to the body if a smoker starts to quit smoking?
Do you know what happens to your body when you decide to stop smoking? Beijing Chaoyang District Center for Disease Control and Prevention has published a document describing the following changes in the body after quitting smoking:
Three days after quitting:
There is less nicotine in the blood, breathing becomes easier, smell and taste more sensitive.
One month after quitting:
After a month, lung function improved a lot, coughing was less, and spirits were better.
Three months after quitting:
Shortness of breath, cough and other symptoms are reduced, heart and lung function is better, infection rate is reduced, breathing is easier.
Nine months after quitting:
Half as likely to develop heart disease as smokers.
Three years after quitting:
Recovery of body functions, and non-smoking peers, smoking has no temptation.
Five years after quitting:
Teeth are no longer visibly black and yellow, and the chance of being targeted by lung cancer, throat cancer and other diseases is also reduced.
In other words, although quitting smoking may have withdrawal effects at first, if you can survive and stick to quitting smoking, you can effectively reduce the risk of cancer.
Many people may wonder, after quitting smoking, can the blackened lungs return to the previous color? It’s hard to get back to a healthy lung color.
After all, many of the harmful substances in tobacco smoke have irreversible effects on the lungs. These harmful substances are difficult to be excreted and damaged lung function is difficult to recover. Therefore, it is not realistic to return to the previous color.
But a study published in Nature suggests that quitting smoking can lead to the proliferation of healthy lung cells, and any time you quit will benefit.
By analyzing healthy airway cells from current smokers, former smokers, adult nonsmokers and children, the researchers found that quitting at any age not only reduced the accumulation of damage, but also awakened some cells that were not affected by tobacco.
