CT screening for lung cancer

Screening is the process of identifying disease in people who do not yet exhibit symptoms. Routine screening tests for cancer include mammograms for breast cancer, colonoscopies for colon cancer and PAP smears for cervical cancer. 

The use of low-dose, helical computerized tomography (CT) scans to detect lung cancer in those at high risk was scientifically validated in research results announced in November 2010 and published in June 2011. Since that time, lung cancer screening centers using responsible practices to screen those at high risk are opening all over the country.

CT screening can find lung cancer when it is at its earliest and most curable stage. Are you at high risk for lung cancer? If so, do you wonder where to get screened? This information will inform you so you can talk with your doctor about your risk and screening.
