Description
For sample adults with at least one biological daughter (BDNUM) who ever had an unknown kind of cancer (BDUKCAN), BDAUKCAN reports the number of the respondent's biological daughters who were under 50 years of age when the unknown kind of cancer was first diagnosed.
Although BDAUKCAN is only available in 2000, the broader series of related questions about cancer "Family History" were part of all of the Cancer Modules, asked every 5 years beginning in 2000. In all years, this section begins with the general comment:
According to the 2000 and 2005 Field Representative's Manuals, the purpose of these family cancer history questions is to "determine the prevalence of cancer in families in the population" to "allow a greater understanding of how data obtained from genetics clinics can be applied to the general population." The 2010 and later Manuals provides a similar rationale, stating that the collection of this data "will allow analysts a greater understanding of how family history relates to cancer."
The Manuals for all three years define "biological" relatives as people related by blood. Thus, a respondent's biological daughter is a daughter related to the respondent by blood (i.e., not a stepdaughter, adopted daughter, foster daughter, or daughter-in-law).
