For this reason, lung cancer is increasingly found in non -makers

He lung cancer has always been associated with Smoking habitThis is no less than the field, because this is considered the main cause of this disease. However, since in recent years the total number of smokers in the world has decreased significantly, the figures of lung cancer should also do this, but it seems that they do not fall into the same share. It is clear that in NOT -COMPARY peopleThe field but why?

According to 2019, the American Oncological Society, around 80% of lung cancer They are associated with tobacco. But there are more reasons. Certainly, Passive smokers They are also at risk of lung cancer. However, less Active smokersThere will also be fewer passive smokers. Then there is a case Radon gasBut, although in some places it reaches dangerous levels, it does not seem that their global levels are quite diverse to significantly affect the figures of patients of non -gums. And, according to a new study published in Respiratory medicine LancetThe real reason why they get more and more smokers is Environmental pollution.

For this reason, only places with the largest amount of pollution are most affected. Although this is a global problem, and we all must fight on our part to solve it.

Tracking lung cancer

The authors of this new study, an international team of scientists, were founded for execution in two data sets. On the one side, World War II of Cancer (Globocan)Whose numbers were collected in 2022. And, on the other, a set Empitations about lung cancer collected around the world from 1987 to 2022.

They noticed that Adenocarcinoma This is the most common type of lung cancer, 45.6% of cases in men and 59.7% in women. These data attracted the attention of researchers, since the adenocarcinoma, the type of cancer, which begins in the glands, is usually not the most common lung cancer. But what This is the most common in non -SMOKOKERSThis is, as explained in the article The science of warningEncouraged them to cross their data with previous research. At the same time, they saw that people who have never tried a cigarette have a clear tendency of a growing trend in cases of lung cancer.

In particular, they saw that lung cancer in people who never smoked was Fifth main cause of mortality Associated with cancer around the world. It develops almost exclusively as adenocarcinoma and is more common in Women and the Asian population.

These recent data are the one that threw the final track. East Asia, especially China, has one of the worst Air qualities around the world. Pollution levels are very high. Therefore, this is an increase in cases of lung cancer in non -suggestive Asians, by the same, is explained by environmental pollution.

This is only the beginning

In this study, its authors intend to increase awareness that, just as campaigns were carried out to stop the consumption of tobacco, similar should be realized to combat environmental pollution. They already exist, of course, but lung cancer This is usually not shown as an argument. Now we know that with a high probability this is one of the consequences that we have not paid enough attention to. And this is only the beginning. There are already several studies that connect air pollution with Development of adenocarcinomaThe field is not only light.

We can improve our lifestyle that we do not smoke and do not drink alcohol, that we train and eat healthy. But if the air remains more and more contaminated, the risk of cancer, both in light and other types, will remain high. Is this a world that we want to leave in the next generation? It is worth thinking about it.
