People who smoke more are less likely to get cancer? Is it wrong that smoking causes cancer?

There is no doubt that smoking causes cancer, and the nicotine in tobacco is very harmful, and this and the tar in it will make your lungs attach some carcinogens.

This sentence is obviously wrong, the more you smoke, the greater the chance of getting lung cancer, don't listen to these rumors and smoke wildly.

There is no basis for this statement; The saying that smoking causes cancer is not wrong, it is true, people who smoke for a long time have a much greater risk of cancer than people who do not smoke.

Because many people have developed the habit of smoking, smoking, smoking is addictive, so once they develop the habit of smoking, it is difficult to quit, they know that it is not good for the body, but it is difficult for them to get rid of smoking.

First, under the influence of the people around them, many people have formed habits that cannot be changed for a while; second, think that you can't harm yourself, and have a fluke mentality; Third, when the pressure is high, in order to relieve stress.

Because smoking is addictive, once you get addicted, it is difficult to quit, so there are still many people who smoke.

It's because a lot of people don't think so, because they think they're the best of them, they don't get this kind of disease, and they can't quit once they smoke.

Causing cancer is a matter of the future, but you can smoke quickly and vividly at the moment, eliminate your worries, and pass the time of boredom.

The main reason is that the current Chinese environment is still more advocating smoking, so there are many people who still can't change the problem of smoking.

Because life is very stressful now, many people want to relieve their inner pressure and depression by smoking.

The nicotine in tobacco will enter the human bloodstream through the oral mucosa within a few seconds, and quickly relieve the physiological smoking craving state of the human body, so people still like to smoke.

This is because there is nicotine in cigarettes, which is an addictive ingredient, so once you get into the habit of smoking, few people can quit it.

Because these people don't really care. Their lives are so miserable that they need tobacco to bring them solace.

Because smoking can relieve stress, make one's mood stable, and let oneself forget about the unhappiness and troubles in one's heart for a while.

Because quitting smoking is hard. Tobacco is an addictive substance that requires strong willpower to quit.

Because cigarettes contain nicotine, nicotine will have a special dependence on the human body.

Modern medicine says.

Lead. Mercury. Arsenic. Harmful to the human body. Can cause cancer.

Radiation damage: Tobacco is more likely to absorb radioactive substances from soil, fertilizer and air than other plants during growth, resulting in more radionuclides in tobacco.

Among them, the more harmful is a radioactive substance called polonium, which volatilizes when people smoke, and accumulates in the body with the smoke flowing into the human body, constantly emitting rays that are invisible to our naked eyes, damaging the body's tissues and cells. It is estimated that if you smoke 30 cigarettes a day, the annual radiation dose to the human body is equivalent to the cumulative dose of 100 X-rays. This irradiation affects the metabolism of tissue cells, causing cell genes to mutate, induce and promote the formation and development of cancer.

Impairment of immune function: Smoking can damage the body's immune function, and this injury is positively correlated with the increased incidence of infection and cancer in smokers. The body's immune system is able to perform its immune function because there is a natural killer cell in the system, NK lymphocytes, which directly inhibits and kills cancer cells.

Smoking, on the other hand, leads to a decrease in NK cell activity, and the more you smoke, the lower your activity. Relevant data show that heavy smokers who smoke more than 150 packs per year have a significant decrease in NK cell activity compared with non-smokers.

Explore: Women may be more susceptible to lung cancer from secondhand smoke.

Damage to cell genes: Tobacco contains many carcinogens, such as nicotine, pyridine, hydrochoic acid, ammonia, tobacco tar, carbon monoxide, aromatic compounds, etc., among which tobacco tar is the most harmful. Cigarette tar contains radioactive isotopes of magnesium, lead, bismuth and epoxides, phenols, benzene, pyrene, etc.

These carcinogens are pervasive, and the best trick is to drill into the gene bases and destroy the structure of DNA. If the damaged DNA is not repaired in time, the diseased gene will be transferred to the offspring cells and become potential cancer cells, and when affected by other factors, the cancer cells will multiply in large numbers and form cancer.

The "reactive oxygen species" produced by cigarette tobaccotoxicity dissolved in water or food lipid peroxides can directly act on the DNA and break its chain into fragments, especially the DNA damage to the presence of oncogene cells is more obvious, thereby promoting gene mutations, cell cancer, and the formation of cancer.

Either way, smoking is bad for your health, not only for you, but also for your friends and family.
