“…This finding is supported by previous studies which suggested that lower educated patients do in fact tend to know less about genetic testing [16,17]. A direct comparison of physicians' predictions with their actual patients' knowledge would be interesting future research.…”

Background: The aim of this study was to assess physicians’ perception of their patients’ knowledge and opinions regarding regular screening, and the association of their perceptions with physician numeracy and patient education level. Methods: We carried out a survey study of 240 obstetrician-gynecologists. Results: Overall, 99.6% physicians perceive that their patients know that breast cancer is hereditary, 86.5% predicted that there is a gene mutation related to breast cancer, and 79.4% predicted that most breast cancer cases occur in women aged 50 years or greater. Physicians with less educated patients thought that their patients would not know about genetic screening, and physicians with more educated patients thought that their patients would know that mammography does not reduce the risk of getting breast cancer. A total of 66.0% of obstetrician-gynecologists answered all 3 numeracy questions correctly. Less numerate physicians were more likely to indicate that their typical patient would agree with the statement about regular mammography screens than the more numerate physicians. Conclusions: Obstetrician-gynecologists expect that their patients know some things about breast cancer and not others. Some of the physicians’ perceptions about patients differ based on numeracy.

“…Some of the possible implications of genetic susceptibility testing that were mentioned by the women have also been found in other studies on public attitudes towards cancer genetic testing, including testing for high-risk genes BRCA1/2 , such as psychological distress [17,19], and fear of insurance or employment discrimination [20]. The negative impact of a positive genetic test result of high-risk genes (BRCA1/2) on a woman’s psychological well-being has been demonstrated, especially in the first month after receipt of the test results [21,22].…”

“…general population [11,12,13,14,15], even if the results were to have no effect on the women’s options for early detection or treatment [16]. Potential concerns by the public that previously have been reported with regard to cancer genetic testing are the expected psychological impacts from a positive test result [11], and potential misuses and confidentiality of genetic information [12,17]. Studying potential responses to clinical innovations before they become part of routine practice allows for the identification of important public concerns, and the possible need for public education [10].…”

Background: Population breast cancer screening programs by mammography are offered to women based on age. It has been suggested that a screening program based on genetic risk profile could be more effective by targeting interventions at those at higher genetic risk. This study explores women’s attitudes towards genetic testing for breast cancer susceptibility in order to target breast cancer prevention. Methods: A qualitative study was conducted using 4 focus groups with 26 women aged 42–73 years. Women were selected irrespective of personal or family history of breast cancer. Discussions were audiotaped and content analyzed. Results: The results show that in general women are positive towards a breast cancer screening program based on genetic risk profile, provided that in the low-risk group, though less frequent, women are still offered mammography screening (i.e. right to screening (a)). Other themes that women addressed were: (b) value of the genetic risk information (e.g. possibilities for cancer prevention at younger ages, less screening burden for low-risk women), (c) personal autonomy (e.g. free choice to undergo testing), (d) dealing with test results (e.g. burden of risk, motivation to reduce the risk), (e) discrimination, and (f) financial aspects and priority (e.g. with respect to other health care programs). Conclusion: These results suggest that women currently offered breast cancer screening based on age have a positive attitude towards population susceptibility screening for breast cancer, but also identified issues that need to be discussed and studied further, especially if women in the low-risk group were no longer to be offered mammography screening.

“…These challenges include the following: lack of primary care providers (PCPs) knowledge about HBOC and limited experience in referring women for genetic counseling 13–15 ; poor systematic collection of family history data 16,17 ; provider difficulty in communicating genetic risk 18–20 ; and poor patient understanding regarding HBOC, the genetic counseling and testing process, and the meaning of genetic testing results. 21–24 Some interventions to address these challenges include continuing medical education for providers and the inclusion of nurses, allied health professionals, and patient navigators in the delivery of communication. However, the evidence regarding effectiveness of these interventions has not been widely examined regarding breast cancer communication between young women and their providers.…”

Background Women younger than 45 years old have lower rates of breast cancer, but higher risk of recurrence and mortality after a cancer diagnosis. African American women are at risk for early onset and increased mortality; Ashkenazi Jewish women are at risk for genetic mutations leading to breast and ovarian cancer. Although younger women are encouraged to talk to doctors about their family history, little is known about these discussions. Materials and Methods In 2015, 167 women aged 18–44 years participated in 20 focus groups segmented by geographic location, age, race/ethnicity, and family history of breast and ovarian cancer. Transcript data were analyzed using NVivo 10 software. Results Although the majority of women talked to their doctor about breast and ovarian cancer, these conversations were brief and unsatisfying due to a lack of detail. Topics included family history, breast cancer screening, and breast self-examination. Some women with and without family history reported that healthcare providers offered screening and early detection advice based on their inquiries. However, few women took action or changed lifestyle behaviors with the intent to reduce risk as a result of the conversations. Conclusions Conversations with young women revealed missed opportunities to: enhance patient-provider communication and increase knowledge about breast cancer screening and surveillance for higher risk patients. Physicians, allied health professionals, and the public health community can better assist women in getting accurate and timely information about breast and ovarian cancer, understanding their family history to determine risk, and increasing healthy behaviors.
