Lung Cancer: 1 person in 5 is not a smoker or other causes

About 20% of people with lung cancer have never smoked. Many of these people are even diagnosed with illness in an incurable stage.

Cancer experts have announced the danger after publishing a report in the Journal of the Royal Society of Medicine that says there is a growing number of non-smoking people being diagnosed with lung cancer. Although smoking is the largest risk factor in developing lung cancer, the American Cancer Society estimates up to 1 out of 5 people with lung cancer in the United States never smoked.

“There is no final answer why non-duhanpiers develop lung cancer,” told Healthline Dr. Giorgio Scagliotti, president of the International Association for the Cancer Study of Tribes and Oncology Professor of Turin University. “However, there are several major risk factors outside smoking related to lung cancer. ”

Secondhand smoke

Lung cancer can be the result of exposure to other smokers. In or out, there is no safe level of exposure to secondhand smoke. The U.S. Center for Disease Control and Prevention defines secondhand smoke as “the international smoke range from the bottom of cigarettes and smoke that smokers absorb”.

Secondhand smoke contains hundreds of toxic chemicals, 70 of which are known to cause cancer and may be the single most important factor in preventing lung cancer from non-duhanpiers.

Radon is a silent killer.

Smoking is the number one preventable factor in lung cancer development. But he is not alone. Exploration to radon (the chemical element) is the second leading cause of lung cancer.

“The radon exposure is widespread on earth, so there is a greater intensification of radon exposure to people working underground and people whose homes have basements”, Scagliotti said.

Air Pollution a Cause of Cancer

In 2013 the International Cancer Research Agency of the World Health Organization (IARC) announced that air pollution was the leading environmental cause of cancer deaths. The IARC monographs are a source of scientific evidence of the substances and exposures caused by cancer. Air pollution can be difficult to avoid.
