FSPSCAN
Full sisters had prostate cancer
Group: Family Cancer History — PERSON

Description

For sample adults with at least one full sister (FSNUM) who ever had cancer of any kind (FSNHCAN), FSPSCAN reports whether the respondent had at least one full sister who ever had prostate cancer.

Although FSPSCAN is only available in 2000, the broader series of related questions about cancer "Family History" were part of both the 2000, 2005, and 2010 Cancer Modules. In all three years, this section begins with the general comment:

We would like to ask you a few questions about your family history of cancer.

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 Manual 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 "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).

I. Related Variables for Full Sister(s) 

Sample adults with at least one full sister who ever had cancer of any kind (FSNHCAN) were asked the follow-up question, "What kinds of cancer did your [full] sister(s) have?" As noted in the 2000, 2005, and 2010 Survey Descriptions, respondents could specify up to two types of cancer for their siblings. Besides prostate cancer, other possible types of cancer that respondents could report for their full sister(s) were:

  • Skin (don't know what kind) (FSSNCAN)
  • Soft tissue (muscle/fat) (FSSTCAN)
  • Unknown kind of cancer (FSUKCAN) (for 2000 only)

When a respondent reported at least one full sister who ever had prostate cancer (FSPSCAN) or one of the other kinds of cancers noted above, the respondent was then asked how many full sisters had ever been told they had prostate cancer (FSNPSCAN) or whatever other kind of cancer had been reported. This information is also available for 1987, although it was not asked as a direct question that year.

Furthermore, when a respondent reported at least one full sister who ever had prostate cancer (FSPSCAN) or one of the other kinds of cancers noted above, the respondent was also asked how many full sisters were under 50 years of age when first diagnosed with prostate cancer (FSAPSCAN) or whatever other kind of cancer had been reported.

The variables related to full sisters with prostrate cancer, testis cancer, or "unknown kind of cancer" are available for 2000 only.

II. Prostate Cancer Variables for Other Biological Relatives 

In addition to questions about full sister(s), the "Family History" section of the 2000, 2005, and 2010 Cancer Modules also included questions about respondents' biological daughter(s), biological son(s), full brother(s) (i.e., brother(s) with the same biological father and biological mother as the respondent), biological father, and biological mother.

Just as questions about full sisters with prostate cancer are included only in 2000, so too are questions about biological mothers and biological daughters with prostate cancer included only in 2000. Questions about biological fathers, biological sons, and full brothers with prostate cancer are available in both 2000 and 2005.

To analyze prostate cancer, researchers may find the following variables useful:

  • Biological daughter(s) had prostate cancer (BDPSCAN) (2000 only)
  • Biological son(s) had prostate cancer (BSPSCAN)
  • Number of biological sons with prostate cancer (BSNPSCAN)
  • Number of biological sons under 50 years of age when first diagnosed with prostate cancer (BSAPSCAN)
  • Full brother(s) had prostate cancer (FBPSCAN)
  • Number of full brothers with prostate cancer (FBNPSCAN)
  • Number of full brothers under 50 years of age when first diagnosed with prostate cancer (FBAPSCAN)
  • Biological father had prostate cancer (BFPSCAN)
  • Biological father under 50 years of age when first diagnosed with prostate cancer (BFAPSCAN)
  • Biological mother had prostate cancer (BMPSCAN) (2000 only)

Similar groups of variables are also available for the other kinds of cancers noted above in (I).

Comparability

FSPSCAN is available only in 2000.
