Can lung cancer be caused by air pollution?
What is the cancer risk from outdoor air pollution? Outdoor air pollution causes roughly 1 in 10 cases of lung cancer. But, it’s important to keep this in perspective. Smoking has a much bigger effect on the risk of developing lung cancer than air pollution.
What type of cancer does air pollution cause?
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.

Which gas is responsible for lung cancer?
Scientists estimate that 15,000 to 22,000 lung cancer deaths in the United States each year are related to radon. Exposure to the combination of radon gas and cigarette smoke creates a greater risk of lung cancer than exposure to either factor alone. The majority of radon-related cancer deaths occur among smokers.
