Lung cancer is the leading cause of cancer deaths among men and women. More people die from the disease each year than of colon, breast, and prostate cancers combined.
More emphasis has been placed on lung cancer screening, a process in which doctors use a low-dose CT scan on patients who are identified as high risk, looking for early signs of the cancer.
Dr. Peter Mazzone, who heads Cleveland Clinic's lung cancer program, explains who should be screened and the potential risks involved.
