What Are the Basics of Lung Cancer?


Lung cancer is a leading type of cancer — and a leading killer — in the United States every year. The good news is many cases of lung cancer are believed to be preventable, as an estimated 90% of lung cancer cases are caused by active smoking, including inhaling secondhand smoke.

However, in some cases, lung cancer has other causes, such as occupational exposure to toxins, especially for those who are high risk due to other lung-related medical problems like asthma. To minimize your risk, make sure you know and understand the basics of lung cancer, including the statistics, risk factors and preventative measures you can take.
