You asked: Can poor air quality lead to lung cancer?

Overwhelming evidence shows that particle pollution in the outdoor air we breathe—like that coming from vehicle exhaust, coal-fired power plants and other industrial sources—can cause lung cancer.

Can poor air quality cause lung cancer?

Air pollution.

In the U.S. dust, smoke, and chemicals in the air cause about 1%-2% of lung cancers. Researchers suspect that polluted air can cause changes in your DNA that may set the stage for a higher risk of the disease. The more air pollution you breathe in, the greater your chances of getting this type of cancer.

Does bad air quality cause cancer?

It’s no surprise that air pollution has been linked with lung cancer. A new study suggests that pollution is also associated with increased risk of mortality for several other types of cancer, including breast, liver, and pancreatic cancer.

Can poor indoor air quality cause cancer?

Poor indoor air quality can cause or contribute to the development of infections, lung cancer and chronic lung diseases such as asthma. People who already have lung disease are at greater risk.

Can bad air quality damage lungs?

How Does Air Pollution Affect the Lungs? Breathing in air pollutants can irritate your airways and may cause shortness of breath, coughing, wheezing, asthma episodes and chest pain. Exposure to air pollution puts you at risk for lung cancer, heart attacks, stroke and in extreme cases, premature death.

Which gas causes lung cancer?

Radon decays quickly, giving off tiny radioactive particles. When inhaled, these radioactive particles can damage the cells that line the lung. Long-term exposure to radon can lead to lung cancer, the only cancer proven to be associated with inhaling radon.

How does air pollution increase lung cancer?

There are a few different ways that particles in air pollution could damage DNA in cells and cause lung cancer. For example, tiny particles may build up in the lungs and change how cells replicate. This could lead to DNA damage which can cause cancer.

What percentage of lung cancer is caused by air pollution?

Worldwide, ambient PM2.5 air pollution was estimated to have contributed to 265,267 lung cancer deaths (95% uncertainty interval [UI], 182,903-350,835 lung cancer deaths) in 2017, or 14.1% (95% UI, 9.8%-18.7%) of all lung cancer deaths.

Can particulate matter cause lung cancer?

In 2013, the International Agency for Research on Cancer (known as IARC), part of the World Health Organization, concluded that particle pollution causes lung cancer. The IARC based its decision on the review of multiple studies from the U.S., Europe, and Asia and the presence of carcinogens on the particles.
