How do you get lung cancer? If you don't smoke? Myparents smoked, but I always hated the way the stuff smelled. When I got older, I made them go outside to smoke, and I haven't been around smokers in years. Sohow could I have lung cancer?

I: I agree with dr. Leeman's answer entirely. Clearly, the most common cause of lung cancer is due to cigarette smoking.

As an added piece of information, exposure to radon gas, usually by way of poorly vented basements, is one of the more likely causes of lung cancer when smoking is not a factor. You live in cook county, illinois and in general, it is listed as a county with moderate potential for levels of radon (in the range of 2-4 pci/l). You may want to have your home assessed for radon levels and if they are elevated have a reputable radon mitigation company discuss options for your home - usually a simple venting system is all that is needed. ...Read more

At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
