Description
For sample adults with at least one full sister (FSNUM) who ever had an unknown kind of cancer (FSUKCAN), FSAUKCAN reports the number of full sisters who were under 50 years of age when their unknown kind of cancer was first diagnosed.
Although FSAUKCAN is only available in 2000, the broader series of related questions about cancer "Family History" were part of both the 2000 and later Cancer Modules. 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 provide 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 years define "full siblings" as people who have "the same biological father and mother." Thus, a respondent's full sister is a sister who has the same biological father and mother as the respondent (i.e., not half-sisters, stepsisters, adopted sisters, foster sisters, or sisters-in-law).
