Abstract
Women with a limited family history of breast cancer may be interested in cancer genetics information although their objective risk of breast cancer may not indicate routine referral to cancer genetics services. This study examined factors related to interest and use of cancer genetics services in a community sample of women with a limited family history of breast cancer (N = 187) who had no previous contact with cancer genetics services. Participants provided demographic information and ratings of perceived risk, cancer distress, attitudes, and intentions to initiate cancer genetics services. Participants were given information about a cancer genetics clinic that served women having concerns about their breast cancer risk. Women were contacted within 6 weeks and 8 months following their study appointment. Six weeks following their study appointment, 25% of women had initiated cancer genetics services. Eight months following their study appointment, 18% of women reported having completed a cancer genetics service appointment. Baseline intentions independently predicted both initiation at 6 weeks and appointment at 8 months. Cancer distress was positively associated with cancer genetics service initiation and appointment. Results suggest that some women with a limited family history of breast cancer are interested in seeking out cancer genetics information. Women with a limited family history of breast cancer may benefit from the availability of cancer genetics information provided through primary healthcare settings.

Notes
Significant family history is defined as for non-Askenazi Jewish women having two first-degree relatives with breast cancer, one of who received the diagnosis before or at age 50; a combination of three or more first- or second degree relatives with breast cancer regardless of age at diagnosis; a combination of both breast and ovarian cancer among first- and second- degree relatives; a first-degree relative with bilateral breast cancer; a first- or second-degree relative with both breast and ovarian cancer at any age; history of breast cancer in a male relative.
The discrepancy between the year of publication of this manuscript and the year of study initiation (2006 vs. 2005) is due to the cited manuscript being in preparation when the study began.

Women recruited through the research registry (n = 25) were not statistically distinct on any study variables when compared to women recruited through community advertisement with the exception of age (M[SD] = 50.6[8.3] vs. 40.5[12.0]; p < .001) and objective risk (M[SD] = 2.2[1.1] vs. 1.2[1.1]; p < .001).
