Description
For sample adults age 40 and older who had a CAT or CT scan in the past 12 months (CAT1YR), CCAT1YR indicates whether at least one of these CAT/CT scans was done of the chest area.
Those with an affirmative response in CCAT1YR were asked whether any of the CAT scans of the chest area were done to check for lung cancer (CCAT1YRYCAN).
For more information about the CAT screen test, or about the purpose of this inquiry, see CAT1YR.
