What Are the Risk Factors for Lung Cancer?

25 Shares

Most people know that smoking raises the risk of lung disease, but did you know that lung cancer can affect anyone—regardless of age or whether you’ve ever smoked?

Understanding the risk factors can help you stay informed and proactive about your health, even if you think your chances are low.

Smoking: The Leading Cause of Lung Cancer

About 80% to 90% of lung cancer deaths in the United States are connected to smoking cigarettes. Using other tobacco products or cigars lowers Lung Cancer Life Expectancy. Comprising more than 7,000 compounds, tobacco smoke is a deadly mix. Many are toxic. At least seventy are recognized to induce cancer in either humans or animals.

Cigarette smokers are 15 to 30 times more likely than non-smoking people to get lung cancer or die from it. Lung cancer risk is raised even by occasional or daily smoking of a few cigarettes. One’s risk increases with increasing years of smoking and daily use of cigarettes.

I’m so glad I never picked up the habit of smoking. I gave it a try, but honestly, I wasn’t a fan—plus, that smell? No thanks!

Although their risk is larger than that of persons who never smoked, those who give up smoking have a reduced risk of lung cancer compared to those who have kept on smoking. Any age of quitting smoking will help to reduce lung cancer risk.

Radon: The Invisible Lung Cancer Threat

Radon develops in water, soil, and rocks. It is not visible, tasteable, or scentable. Radon can become trapped and accumulate in the air within homes or buildings, it enters via cracks or holes. Those who live or work in these buildings and houses breathe in significant radon levels. Over extended lengths of time, radon can lead to lung cancer.

According to estimates by the U.S. Environmental Protection Agency (EPA), radon accounts for roughly 21,000 annual lung cancer fatalities. Those who smoke run a greater risk of lung cancer from radon exposure than those who do not smoke.

Still, the EPA believes that those who have never smoked cigarettes account for more than 10% of radon-related lung cancer deaths. High radon levels abound in almost one in every fifteen American homes.

Asbestos Exposure: A Silent Hazard in Older Buildings

As a mineral fibre, asbestos is present in soil and rocks. Breathing it in raises your chance of lung cancer. Many homes and older structures still contain asbestos, but generally speaking, it is not considered dangerous as long as it is not airborne from demolition, restoration, or decay.

Manufacturers have long used asbestos in insulation and other goods. Those who handle these goods risk exposure. Luckily, criteria have been established to reduce these hazards.

A person’s risk of lung cancer may be raised by family history; this risk increases with additional hazards like smoking.

Family History: When Genetics Play a Role in Lung Cancer

Should a family member of yours have lung cancer, you are twice as likely to get cancer yourself without a family history of the disease.

The likelihood of lung cancer is even higher for those with two or more first-degree relatives, brothers, sisters, parents, or children, who developed it. There is no such thing as a safe cigarette or a safe level of smoking in households where lung cancer runs in history.

Occupational Exposure: Workplace Hazards That Raise Your Risk

Mesothelioma is caused by asbestos exposure. While it is not utilized now, asbestos was once widely used in insulation and building materials.

Over the years of employment, those who worked in construction, shipbuilding, some kinds of industry, as firefighters and in other related sectors could have come into contact with asbestos.

Of all the mesothelioma cases documented, seventy to eighty percent have been connected to occupational asbestos exposure.
