What Is The Cause?
The researchers speculate that it could be due to the rising levels of pollution. In fact, several previous studies already found a link between air pollution and adenocarcinoma risk increase. This makes sense considering that the regions with the most cases are also among the most polluted in the world. While many cancers can develop due to personal choices, this new risk is instead driven by issues that face the planet and its inhabitants as a whole.
However, air pollution is not the only factor potentially leading to an increase in lung cancer in non-smokers. Other risk factors include radon (a gas that emanates from the ground), secondhand smoke, asbestos, and genetics. Poor ventilation during cooking can also dramatically increase your lung cancer risk. Some of the symptoms of lung cancer include chest pains, wheezing, fatigue, a persistent cough, and unexpected loss of weight. Non-smokers tend to develop different tumors from smokers. The lung cancer they develop typically has driver mutations that can be targeted. If doctors are able to determine exactly which driver mutation caused the cancer, there is a better chance they can treat it.
