This study addresses a disparity in services related to the rare but serious condition of HBOC. In a randomized delayed intervention control trial, the investigators were able to identify high-risk but predominantly unaffected women among callers seeking referrals to free cancer screening. The investigators compared an immediate offer of a genetic counseling appointment to information on hereditary breast and ovarian cancer sent by mail. Our study demonstrated that when a diverse population of low-income women calls a trusted information and referral source, it is possible to both engage them on a topic that is different from the purpose for their call and to recruit them for participation in research.
