Lung cancer is increasing in people who never smoked because of air pollution, according to a new study. The study found that a certain type of lung cancer, called adenocarcinoma, has become more common and is linked to air pollution. This type of lung cancer is now the most common among both men and women who never smoked. Smoking rates are going down, but lung cancer cases in non-smokers are rising because of pollution. Lung cancer is a leading cause of cancer deaths, and it is important to protect our air quality to prevent this disease. The study found that in 2022, over 900,000 women were diagnosed with lung cancer, and most cases were the adenocarcinoma type. Air pollution is a major factor in the rising cases of lung cancer in non-smokers. It's important for us to protect our environment and make sure we have clean air to breathe. Remember, we need to take care of our lungs and stay away from pollution to keep ourselves healthy.
