Description
For sample adults with at least one biological son (BSNUM) who ever had melanoma (BSMNCAN), BSAMNCAN reports the number of the respondent's biological sons who were under 50 years of age when the melanoma was first diagnosed.
BSAMNCAN is one of a series of related variables in the "Family History" section of 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 this and other 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 these data "will allow analysts a greater understanding of how family history relates to cancer."
The Manuals for all years define "biological" relatives as people related by blood. Thus, a respondent's biological son is a son related to the respondent by blood (i.e., not a stepson, adopted son, foster son, or son-in-law).
Comparability
Although BSAMNCAN is substantively comparable across all years, users should note two changes in the recoding of values that may affect analyses of data from multiple cancer supplement years.
The first, and most recent, change affects the top code value for BSAMNCAN. Prior to 2015, BSAMNCAN was top coded at 21. Starting in 2015, BSAMNCAN was top coded at 3. The second change, affecting how missing data values were treated for sample adults who completed only part of the cancer supplement, took place between the 2000 and 2005 cancer supplement. In 2000, persons who answered less than 50 percent of the questions in the supplement had a value of "not ascertained" automatically inserted in the appropriate fields of the Cancer Control Module file, whereas in 2005 and later years, persons who answered none of the questions in the supplement had a value of "not ascertained" automatically inserted in the appropriate fields of the Cancer Control Module file.
