Definition
HHCANCERDIAGLUNG indicates whether any member of the household had been diagnosed with lung cancer. The question specifies no timeframe, so the diagnosis might have been recent or in the distant past, or might even apply to a deceased former household member.
The information in HHCANCERDIAGLUNG is taken from the household record and applies to regular household residents, not temporary visitors. Researchers may wish to exclude visitors using the RESIDENT variable (with visitors coded "2") when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
