What gas is the second leading cause of lung cancer?

Radon is the second leading cause of lung cancer in the United States. Nationally, the EPA estimates that about 21,000 people die each year from radon-related lung cancer. Only smoking causes more lung cancer deaths. You can take steps to reduce and control the amount of radon in your home.

What is the second leading cause of lung cancer?

After smoking, radon is the second leading cause of lung cancer in the United States. Radon is a naturally occurring gas that forms in rocks, soil, and water.

Which gases causes 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.

What are the major causes of lung cancer?

Smoking tobacco is by far the leading cause of lung cancer. About 80% of lung cancer deaths are caused by smoking, and many others are caused by exposure to secondhand smoke. Smoking is clearly the strongest risk factor for lung cancer, but it often interacts with other factors.

What percentage of lung cancer is caused by radon gas?

Does radon gas cause lymphoma?

A new report finds a statistically-significant, positive association between high levels of residential radon and the risk of hematologic cancer (lymphoma, myeloma, and leukemia) in women.

How long until radon causes cancer?

If a person has been exposed to radon, 75% of the radon progeny in the lungs will become harmless lead particles after 44 years. When a particle damages a cell to make it cancerous, the onset of lung cancer takes at least five years, but often takes 15 to 25 years and even longer.

What is the most common cause of lung cancer in nonsmokers?

Radon gas: Exposure to radon gas is considered to be one of the causes of lung cancer in nonsmokers, accounting for about 21,000 lung cancer deaths each year.

What causes lung cancer besides smoking?

Lung cancer can be caused by many risk factors other than smoking cigarettes, pipes, or cigars. These risk factors include exposure to other people’s smoke (called secondhand smoke), radon, air pollution, a family history of lung cancer, and asbestos.

Why do cigarettes cause cancer?

Chemicals from cigarettes damage DNA. Cigarette chemicals make it harder for cells to repair any DNA damage. They also damage the parts of DNA that protect us from cancer. It’s the build-up of DNA damage in the same cell over time that leads to cancer.
