Admit it. You have probably wondered why you or your loved one was unlucky enough to get lung cancer while that obnoxious neighbor or coworker has smoked 2 packs a day for 50 years and doesn’t even have a cough. In fact, only about 15% of male smokers and 10% of female smokers eventually develop lung cancer. The field at large has been searching for why some smokers get lung cancer and others don’t for many years, and while progress has been made the answer has been elusive.
