Mayo Clinic Radio: Lung Cancer Screening

Lung cancer is the leading cause of cancer deaths in the U.S., according to the Centers for Disease Control and Prevention. Lung cancer claims more lives each year than colon, prostate, ovarian and breast cancers combined. Because lung cancer typically doesn\'t cause signs and symptoms in its earliest stages, the disease often is not diagnosed until the advanced stages. Treatment for lung cancer can include radiation, chemotherapy and surgery to remove the cancer.
