Why are those who quit smoking more likely to develop lung cancer? Should I quit smoking?

Hahaha, I can't quit saying it clearly!!

When you start smoking, you have already planted the hidden danger of lung cancer in your body, and long-term smoking can cause lung damage, and even if you quit smoking, the risk of cancer is three times higher than that of ordinary people. Quitting smoking does not eliminate lung cancer, and quitting smoking does not reduce the risk of lung cancer, which only decreases over time, so it is imperative to quit smoking.

Quitting smoking and getting lung cancer is the result of long-term smoking. The real cause of lung cancer is not caused by quitting smoking, but by the cumulative effect of years of smoking, and the harmful substances in tobacco cause damage to the body over the years. For health reasons, it is imperative to quit smoking.

Because smoking has damaged your lungs before, even if you have quit smoking now, it is impossible to return your lungs to the original healthy state, of course, it is still necessary to quit smoking, after all, not quitting smoking will only make your lungs more damaged.

Why are those who quit smoking more likely to develop lung cancer? Should I quit smoking?

It is an indisputable fact that long-term smoking can lead to impaired lung function, so if you want to improve lung function, you must quit smoking as soon as possible. My university teacher, Mr. Zhou, is such a smoker, who started smoking in his teens until he was 40 years old, and once went for an examination and found a calcification point in his lungs.

I thought that after quitting smoking, I couldn't get involved with lung cancer, but I didn't expect that after 20 years of quitting smoking, I suddenly became thinner, and my chest always hurt faintly, and my legs were swollen, so I went to the hospital for an examination under the persuasion of my family.

I didn't expect to get lung cancer after a check, Mr. Zhou couldn't figure it out, he was fine after smoking for so many years, but he got lung cancer after quitting. If you quit, you can't escape lung cancer, it's better not to quit than to quit, do you have the same thoughts as Mr. Zhou? Let's take a look at the doctor's explanation.

Why do I get lung cancer if I quit smoking?

Our current research on lung cancer proves that the most relevant factor for the occurrence of lung cancer is smoking, so we advocate smoking cessation to reduce the risk of lung cancer. Many smokers take it for granted that if they quit smoking, they won't get lung cancer again.

As everyone knows, the pathogenesis of cancer lies in the genetic mutation of cells in the body, and the lung cells of smokers are more likely to become cancerous than non-smokers, and the chance of getting lung cancer is 10 to 13 times higher than that of non-smokers.

We emphasize that people who smoke have a higher risk of developing lung cancer, which does not mean that if you don't smoke, you won't get lung cancer, but that smoking will definitely get lung cancer. Quitting smoking does not eliminate lung cancer, and quitting smoking does not immediately reduce the risk of lung cancer, which decreases over time.

For example, Zhou Lao quit smoking because he had calcified points in his lungs because he had been smoking for a long time, so his lungs already had early symptoms of lung cancer. And he smoked early and smoked a lot, so he must be among the susceptible to cancer. However, as the disease progressed, a lung tumor was finally discovered, and on the surface, it felt that lung cancer was caused by quitting smoking.

According to the American Cancer Society, when you start smoking, you have already planted the hidden danger of lung cancer in your body, and even if you have quit smoking for 25 years, the risk of developing lung cancer is three times higher than the average person.

Of course, this does not mean that you just break the jar and stop smoking, if you choose to quit smoking, then the chance of developing lung cancer will drop by 39% after 5 years, and it will continue to decline with time, so it is still necessary to quit smoking.

You can definitely get lung cancer if you don't smoke, because that's why secondhand smoke, thirdhand smoke, and now legislation against smoking in public places or indoors is the fundamental reason why secondhand smoke is widely publicized. Because smoking is inherently more likely to get lung cancer, only 30% of the smoke is inhaled into one's lungs, and 70% of the smoke will pass through the mouth or nose, and finally diffuse in the surrounding air, walls or floors. If you walk by or have a family member, you will inhale smoke and inhale your own lungs, which may cause lung cancer.

At present, there are about 300 million people in our country who smoke, and 100 million of them are passive smokers, so in the latest lung cancer data, the incidence of lung cancer among women who have never smoked is also increasing. Although they do not smoke themselves, most of them have a history of passive smoking.

If some people have lung cancer susceptibility factors and have this family history, even if they do not smoke and smoke passively, they may get lung cancer.

There is disturbing news about lung cancer: not smoking does not mean staying away from lung cancer. As many as 10 to 15 percent of lung cancer patients have no history of smoking, and in the United States alone, tens to tens of thousands of people die each year.

The cause of lung cancer in nonsmokers is unknown, but researchers suspect it is related to genetic damage caused by exposure to carcinogens, such as asbestos, radon, certain solvents or passive smoking.

A large study has just been conducted, based on 2.4 million non-smokers with lung cancer in Europe, North America and Asia, providing new information about lung cancer risk. The study found that male non-smokers were more likely to die from lung cancer than female non-smokers, but the overall risk was not increased. "Two cognitive misunderstandings:

Women have a relatively high risk of developing lung cancer, and the risk is increasing day by day. Both of these have attracted public attention. Michael J., the principal investigator of epidemiology at the American Cancer Society who led the study

Dr. Thun said. Of course, taking Rh2 can prevent cancer.

Smoking does cause lung cancer, and it has been reported that smokers are 20 times more likely to develop cancer than non-smokers, and non-smokers are also more likely to develop lung cancer.

First of all, the cause of lung cancer is not only smoking, so people who do not smoke will also develop lung cancer for various reasons, but the chance of developing cancer is much smaller than that of smokers.

Secondly, after quitting smoking, the chance of cancer will be significantly lower than that of smoking, which is certain, and the benefits of quitting smoking are far more than that, so quit smoking as soon as possible, and the sooner you quit, the more benefits.
