BACKGROUND
Women with a family history of breast cancer are at increased risk for developing cancer and, therefore, might be expected to engage in early detection practices more actively than women without a family history. Alternatively, women with a family history may avoid thinking about cancer and have attitudes and practices that do not promote early detection.
METHODS
This study examined breast cancer attitudes and practices among African American women aged >or=50 who had not had a mammogram in the last 2 years.
RESULTS
Phone survey data from 320 female clients of low-income, rural primary care clinics (91% African American) indicated that 15% self-reported a family history of breast cancer (FH(+)). Half of the FH(+) women did not know their relative risk of developing breast cancer. Of those providing a risk estimate, 67% perceived themselves at low risk compared with other women their age. Perceived relative risk was comparable between FH(+) and FH(-) women. Further, FH(+) women did not indicate greater worry about breast cancer, nor did they have more accurate knowledge of mammography recommendations than FH(-) women. Two thirds of FH(+) women had never had a mammogram. Monthly breast self-examination did not differ between FH(+) and FH(-) women.
CONCLUSIONS
Thus, neither knowledge of a positive family history nor perceived relative risk of breast cancer was associated with either increased or decreased early detection practices among these low-income, rural, African American women who have underused mammography. Furthermore, a substantial proportion of FH(+) women had not ever participated in screening mammography. Interventions to increase mammography rates in this population of underusers are indicated.
背景
有乳腺癌家族史的女性患癌风险增加,因此,她们可能比没有家族史的女性更积极地参与早期检测。或者,有家族史的女性可能会回避思考癌症,其态度和行为不利于早期检测。
方法
本研究调查了年龄≥50岁、过去两年未进行过乳房X光检查的非裔美国女性对乳腺癌的态度和行为。
结果
来自低收入农村初级保健诊所320名女性患者(91%为非裔美国人)的电话调查数据显示,15%的女性自称有乳腺癌家族史(FH(+))。一半有家族史的女性不知道自己患乳腺癌的相对风险。在给出风险估计的人中,67%的人认为自己与同龄女性相比风险较低。有家族史和无家族史的女性感知到的相对风险相当。此外,有家族史的女性对乳腺癌并不更担心,她们对乳房X光检查建议的了解也不比无家族史的女性更准确。三分之二有家族史的女性从未做过乳房X光检查。有家族史和无家族史的女性每月乳房自我检查情况没有差异。
结论
因此,在这些乳房X光检查使用率低的低收入农村非裔美国女性中,无论是有阳性家族史还是感知到的乳腺癌相对风险,都与早期检测行为的增加或减少无关。此外,相当一部分有家族史的女性从未参加过乳房X光筛查。有必要采取干预措施提高这一低使用率人群的乳房X光检查率。
