Your question: Which gas causes lung cancer?

Which gas is responsible for lung cancer?

Radon gas in the air breaks down into tiny radioactive elements (radon progeny) that can lodge in the lining of the lungs, where they can give off radiation. This radiation can damage lung cells and eventually lead to lung cancer.

Which gas causes cancer?

Radon is a naturally-occurring radioactive gas that can cause lung cancer.

What is the main cause for lung cancer?

Cigarette smoking is the number one risk factor for lung cancer. In the United States, cigarette smoking is linked to about 80% to 90% of lung cancer deaths. Using other tobacco products such as cigars or pipes also increases the risk for lung cancer. Tobacco smoke is a toxic mix of more than 7,000 chemicals.

What is radon gas?

Radon is a natural radioactive gas which comes from the decay of uranium in rocks and soil. It is colourless, odourless and tasteless. In outside air the levels of radon are low but it collects in enclosed places, such as houses, workplaces and other buildings.

Does radon Gas Cause 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.

Does natural gas cause cancer?

Natural gas also contains smaller amounts of other compounds, such as benzene, that cause cancer as well as anemia and other blood disorders. In the Los Angeles area, benzene is normally present at minuscule levels of 0.1 to 0.5 parts per billion, according to the South Coast Air Quality Management District.

Does radon gas rise?

Radon can rise to dangerous levels when it becomes trapped inside your home or other buildings, often collecting in lower floors. Experts recommend testing for radon during the colder months because radon levels are historically found to be higher.

Can gases cause cancer?

Radon is a cancer-causing radioactive gas. You can’t see, smell, or taste radon. But it may be a problem in your home. Studies performed at the University of Iowa have helped show that radon is the second leading cause of lung cancer and the leading environmental cause of cancer deaths in the United States.
