Am I At Risk for Lung Cancer?
There is no sure way to know if you’re going to get lung cancer. Certain factors can make you more likely to get lung cancer than another person. These are called risk factors. However, just because you have one or more risk factors does not necessarily mean you will get lung cancer. In fact, you can have all the risk factors and still not get lung cancer. Or you can have no known risk factors and still get the disease.
Doctors estimate that more than 90% of lung cancer cases are related to smoking. So not smoking, or stopping if you do smoke, is the best way to protect yourself from lung cancer.
Even if you aren’t a smoker, studies show that being around smoke increases your risk for lung cancer. It is a good idea to avoid exposure to smoke. Still, a small percentage of people who get lung cancer have never smoked or been around secondhand smoke. So, not all lung cancer patients were smokers. And not all smokers get lung cancer.
Look at the following statements. If you say yes to any of them, you are at an increased risk for lung cancer. Each time you say yes, ask yourself if you’re doing all you can to control that particular risk factor. It may seem hard, but your efforts can have a big payoff in terms of your health and quality of life. Ask your doctors and your loved ones to help you think of ways that will help you succeed at lowering your risk for lung cancer.
I smoke cigarettes.
Tobacco contains substances called carcinogens, which harm cells in your lungs. After a while, these damaged cells may turn into cancer. Each of these things makes the chance that you will develop lung cancer even higher.

If you are a heavy smoker, your risk of developing cancer is 10 to 25 times higher than that of a nonsmoker. Some doctors think women who smoke or who are exposed to tobacco smoke are more likely to have lung cancer than men. Several studies have shown this to be true.
Some people believe that there is no reason to quit smoking because the damage has already been done. That’s not true. It’s true that anyone who has smoked has more of a risk of getting lung cancer than someone who has never smoked. Still, quitting smoking can reduce your risk for cancer by more than half. And the longer you don’t smoke, the more your risk decreases. So it’s worth the effort to do all you can to become a nonsmoker.
I smoke cigars or a pipe.
Some people believe that smoking cigars or a pipe is not as bad for them as smoking cigarettes. But any kind of smoking increases your risk for lung cancer. If you smoke cigars or pipes, you have a higher risk of developing lung cancer than people who don’t smoke them. If you have smoked for a long time, you have an even higher chance of developing lung cancer. Your risk for lung cancer also depends on how much you smoke every day.
I am around a lot of smokers, so I am often exposed to secondhand smoke.
If you’re around smokers, you have a higher risk of getting lung cancer. Being around secondhand smoke is called involuntary, or passive, smoking. Secondhand smoke has nearly all the carcinogens as the smoke inhaled by smokers. Your risk for lung cancer is higher if you have spent many years being exposed to smoke. One study showed that the risk for lung cancer doubles for people who are around smoke for 25 or more years.
I work in a mine or have high levels of radon in my home.
Radon is a gas that is found in soil and rocks. You can’t see, smell, or taste radon. Still, it can harm your lungs. People who work in mines have a higher risk of developing lung cancer. So do those who live in houses with radon. The amount of radon in your home depends upon ventilation and how far you are from the source. The only way to know how much radon is in your home is to have it tested and then take action if the level is high. To find a professional near you to test the radon level in your home, go to the U.S. Environmental Protection Agency’s website, at www.epa.gov/iaq/whereyoulive.html. You can also talk with a radon specialist at 1–800–55–RADON (1–800–557–2366). To talk with a Spanish speaking specialist, call 1–800–SALUD–12 (1–800–725–8312). If you are around radon and you smoke, your risk for lung cancer is even greater, so you should do all you can to stop smoking.
I have worked or currently work with asbestos.
Asbestos is a group of minerals. They’re used in shipbuilding, insulation, and some kinds of car repairs. If you breathe in tiny pieces of asbestos, they can get stuck in your lungs and harm your lung cells. If you work near asbestos and you smoke, your risk for lung cancer is high. In fact, it can be nearly 100% higher compared with someone who doesn’t smoke and hasn’t been exposed to asbestos. That gives you an even greater incentive to quit smoking.
If you work with asbestos, make you sure you follow the guidelines for working with it safely. If you have questions, call:
I have lung disease.
If you have lung diseases such as tuberculosis (TB), you have a greater chance of getting lung cancer. Lung cancer sometimes develops when there is scar tissue from TB in the lungs.
I live in a city with a high level of air pollution.
If you breathe in a lot of air pollution over a long period of time, you may have a higher risk of developing lung cancer. But this risk is relatively small compared with the risk for smoking.
I have had lung cancer before.
If you’ve had lung cancer before, you have a higher chance of getting lung cancer again. If you quit smoking after having lung cancer, your chance of getting it again is reduced.
