Lung cancer screenings save lives but are unfamiliar to most. Doctor explains what to know.

Lung cancer claims the lives of about 370 Americans every day, but the majority of people are unfamiliar with life-saving screenings available for the disease. 

According to the American Lung Association, only 38% of those surveyed were aware of that lung cancer screening is available for those at high risk. Even less, 28%, knew lung cancer is the leading cause of cancer deaths in the U.S.

On "CBS Mornings" Thursday, Dr. Céline Gounder, CBS News medical contributor and editor-at-large for public health at KFF Health News, said this needs to change.
