Why do doctors keep telling people to quit smoking when some people smoke their whole lives and don’t get cancer?

Smoking is harmful to health, but there are always various arguments to shake the determination of smokers to quit smoking. Is it true that smoking is a personal freedom; that quitting is bad for your health because you gain weight; that many people who smoke do not get cancer; and that …… is right? What should you do if your resolve to quit is shaken, or if a friend or relative refuses to quit for these reasons? Let’s see what doctors have to say! Some people have smoked all their lives without getting cancer. Refusing to quit smoking for this reason is similar to putting your hopes of making money on buying lottery tickets when others are getting rich. Smoking does not necessarily mean that you get lung cancer, but there is clear evidence that people who smoke have a higher risk of developing cancer than people who do not smoke. Some non-smokers also get lung cancer because other factors besides smoking can cause lung cancer, such as long-term secondhand smoke, dust, radioactive pollution, and genetic factors. However, the percentage of non-smokers who get lung cancer is much higher than that of smokers. Smoking not only leads to the occurrence of many tumors such as lung cancer and oral cancer, but some critical diseases that are not cancer, such as heart attack and brain infarction, are also related to smoking. In short, don’t take any chances, smoking is not a good habit, quit early and benefit early. Smoking is a personal freedom. Smoking is a behavior that affects the health of more than just the smoker. Smoke spreads into the environment, bringing secondhand smoke to others in the same environment, and is not very public-spirited. There is also a relatively new concept of “third-hand smoke,” which refers to the harmful substances left behind by cigarette smoke that can be deposited on furniture, clothing, and even a person’s hair and skin. These residues can exist for months at a time. Imagine a room where people often smoke, does it smell even when no one is smoking? The harm produced by these substances is even more pronounced in young children. Because young children’s respiratory systems are not yet developed, they are more likely to cause bronchitis and bronchial asthma, which are diseases. Even if smokers smoke outside, the exposure of young children who are directly exposed to them is still about ten times higher than that of young children who live in an environment without smokers because they share a room. Therefore, it is untenable to use personal freedom as a reason not to quit smoking. Quitting smoking is not good regardless of how long you have been smoking There is no such thing as quitting smoking being bad instead. No matter how long you have been smoking, quitting is good for your body. Many people feel that quitting smoking will make you fat and bad for your body, but in fact quitting smoking is not necessarily fattening. The reason why many people feel fat after quitting smoking is related to changes in eating habits, such as mood swings after quitting smoking, and many people will turn it into appetite. In addition, after quitting smoking also taste sensitivity will also increase, appetite will be better. The ideal way to quit smoking is, of course, to control your appetite and eat a balanced diet. However, when there are difficulties, we still prefer to focus on quitting smoking first, and allow appropriate relaxation of dietary restrictions, even if some weight gain is accepted. After successfully quitting smoking, we then gradually develop a balanced diet and our weight will improve. People who are particularly addicted to smoking, suddenly quit smoking will indeed have discomfort, such as anxiety, depression, insomnia, these discomfort has the risk of triggering cardiovascular accidents. From this point of view, old smokers suddenly quit smoking is harmful, but continue smoking is more harmful. For people who have smoked for a long time, it is recommended to do a tobacco dependence assessment in a smoking cessation clinic and use some medication to help quit according to the results. This will both improve the success rate of quitting and reduce the discomfort associated with quitting smoking.
