Breathing Dirty Air: How Pollution Harms Our Lungs

The Hidden Danger

Air pollution is a serious issue that affects our health in many ways. Since 2013, experts have confirmed that it can cause cancer. People living in areas with poor air quality are at a higher risk of developing lung cancer. In fact, air pollution is the second leading cause of early deaths worldwide, responsible for about 14% of lung cancer cases globally.

The Role of Fine Particles

Scientists are particularly interested in fine particles, known as PM2.5, because they can be very harmful. Recent studies have shown that these tiny particles can cause changes in our cells that lead to cancer. This is especially true for certain types of lung cancer that have specific genetic mutations.

The Urgent Need for Action

It is crucial for researchers and health professionals to address this issue. Reducing air pollution is not only important for our health but also for the environment. Climate change is a major factor that worsens air quality. Therefore, fighting against climate change is also essential in improving the air we breathe.
