Influences of race and breast density on related cognitive and emotion outcomes before mandated breast density notification.

ABSTRACT: RATIONALE:Many states have adopted laws mandating breast density (BD) notification for applicable women; however, very little is known about what women knew or felt about BD and related breast cancer (BC) risk before implementation of BD notification laws. OBJECTIVE:We examined between-race differences in the extent to which having dense breasts was associated with women's related BD cognition and emotion, and with health care providers' communication about BD. METHODS:We received surveys between May and October of 2015 assessing health care provider (HCP) communication about BD, BD-related knowledge, BD-related anxiety and BC worry from 182 African American (AA) and 113 European American (EA) women in the state of Michigan for whom we had radiologists' assessments of BD. RESULTS:Whereas having dense breasts was not associated with any BD-related cognition or emotion, there were robust effects of race as follows: EA women were more likely to have been told about BD by a HCP, more likely to know their BD status, had greater knowledge of BD and of BC risk, and had greater perceptions of BC risk and worry; AA women had greater BD-related anxieties. EA women's greater knowledge of their own BD status was directly related to the increased likelihood of HCP communication about BD. However, HCP communication about BD attenuated anxiety for AA women only. CONCLUSION:We present the only data of which we are aware that examines between-race differences in the associations between actual BD, HCP communication and BD related cognition and emotion before the implementation of BD notification laws. Our findings suggest that the BD notification laws could yield positive benefits for disparities in BD-related knowledge and anxiety when the notifications are followed by discussions with health care providers.

Project description:Prior research shows between-race differences in women's knowledge and emotions related to having dense breasts, thus suggesting that between-race differences in behavioral decision-making following receipt of breast density (BD) notifications are likely. Guided by the theory of planned behavior, this study examined differences in emotion-related responses (i.e., anxiety, worry, confusion) and behavioral cognition (e.g., intentions, behavioral attitudes) following receipt of BD notifications among African American (AA) and European American (EA) women. This study also examined whether race-related perceptions (i.e., discrimination, group-based medical mistrust), relevant knowledge and socioeconomic status (SES) explained the between race differences.Michigan women (N = 457) who presented for routine screening mammogram and had dense breasts, no prior breast cancer diagnoses, and had screen-negative mammograms were recruited from July, 2015 to March 2016. MANOVA was used to examine between race differences in psychological responses (i.e., emotional responses and behavioral cognition), and a multi-group structural regression model was used to examine whether race-related constructs, knowledge and SES mediated the effect of race on emotional responses and behavioral cognition. Prior awareness of BD was accounted for in all analyses.AA women generally reported more negative psychological responses to receiving BD notifications regardless of prior BD awareness. AA women had more favorable perceptions related to talking to their physicians about the BD notifications. Generally, race-related perceptions, SES, and related knowledge partially accounted for the effect of race on psychological response. Race-related perceptions and SES partially accounted for the differences in behavioral intentions. Between-race differences in emotional responses to BD notifications did not explain differences in women's intentions to discuss BD notifications with their physicians.Future examinations are warranted to examine whether there are between-race differences in actual post-BD notification behaviors and whether similar race-related variables account for differences.

Project description:BackgroundDespite widespread implementation of mammographic breast density (MBD) notification laws, the impact of these laws on knowledge of MBD and knowledge of breast cancer risk is limited by the lack of tools to promote informed decision-making in practice.ObjectiveTo develop and evaluate whether brief, personalized informational videos following a normal mammogram in addition to a legislatively required letter about MBD result can improve knowledge of MBD and breast cancer risk compared to standard care (i.e., legislatively required letter about MBD included with the mammogram result).Design/participantsProspective randomized controlled trial of English-speaking women, age 40-74 years, without prior history of breast cancer, receiving a screening mammogram with a normal or benign finding (intervention group n = 235, control group n = 224).Interventionbrief (3-5 min) video, personalized to a woman's MBD result and breast cancer risk.Main measuresPrimary outcomes were a woman's knowledge of her MBD and risk of breast cancer. Secondary outcomes included whether a woman reported that she discussed the results of her mammogram with her primary care provider (PCP).Key resultsRelative to women in the control arm, women in the intervention arm had greater improvement in their knowledge of both their personal MBD (intervention pre/post 39.2%/ 77.5%; control pre/post 36.2%/ 37.5%; odds ratio (OR) 5.34 for change for intervention vs. control, 95% confidence interval (CI) 3.87-7.36; p < 0.001) and risk of breast cancer (intervention pre/post: 66.8%/74.0%; control pre/post 67.9%/ 65.2%; OR 1.42, 95% confidence interval (CI) 1.09-1.84; p = 0.01). Women in the intervention group were more likely than those in the control group to report discussing the results of their mammogram with their PCP (p = 0.05).ConclusionsBrief, personalized videos following mammography can improve knowledge of MBD and personal risk of breast cancer compared to a legislatively mandated informational letter.

Project description:ImportanceWhether the benefits of notifying women about breast density outweigh the potential harms to inform current and future mammogram screening practice remains unknown.ObjectiveTo assess the effect of mammographic breast density notification and information provision on women's intention to seek supplemental screening and psychological outcomes.Design, setting, and participantsA 3-arm online randomized clinical trial was conducted from August 10 to 31, 2021. Data analysis was conducted from September 1 to October 20, 2021. Participants included Australian residents identifying as female, aged between 40 and 74 years, with no history of breast cancer who were residing in jurisdictions without existing breast density notification with screening mammograms.InterventionsWomen were randomized to receive 1 of the following hypothetical breast screening test result letters: screening mammogram result letter without breast density messaging (control), screening mammogram result letter with breast density messaging and an existing density information letter taken from a screening service in Australia (intervention 1), and screening mammogram result letter with breast density messaging and a health literacy-sensitive version of the letter adapted for people with lower health literacy (intervention 2).Main outcomes and measuresPrimary outcomes were intention to seek supplemental screening; feeling anxious (uneasy, worried, or nervous), informed, or confused; and having breast cancer worry.ResultsA total of 1420 Australian women were randomized and included in the final analysis. The largest group consisted of 603 women aged 60 to 74 years (42.5%). Compared with the control cohort (n = 480), women who received density notification via intervention 1 (n = 470) and intervention 2 (n = 470) reported a significantly higher intention to seek supplemental screening (0.8% vs 15.6% and 14.2%; P < .001) and feeling anxious (14.2% vs 49.4% and 48.5%; P < .001), confusion (7.8% vs 24.0% and 23.6%; P < .001), and worry about breast cancer (quite/very worried: 6.9% vs 17.2% and 15.5%; P < .001). There were no statistically significant differences in these outcomes between the 2 intervention groups.Conclusions and relevanceIn this randomized clinical trial, breast density notification and information integrated with screening mammogram results increased women's intention to seek supplemental screening and made women feel anxious, confused, or worried about breast cancer. These findings have relevance and implications for mammogram screening services and policy makers considering whether and, if so, how best to implement widespread notification of breast density as part of mammography screening.Trial registrationACTRN12621000253808.

Project description:BACKGROUND:Twenty-eight states have passed breast density notification laws, which require physicians to inform women of a finding of dense breasts on mammography. OBJECTIVE:To evaluate changes in breast cancer stage at diagnosis after enactment of breast density notification legislation. DESIGN:Using a difference-in-differences analysis, we examined changes in stage at diagnosis among women with breast cancer in Connecticut, the first state to enact legislation, compared to changes among women in control states. We used data from the Surveillance, Epidemiology, and End Results Program (SEER) registry, 2005-2013. PARTICIPANTS:Women ages 40-74 with breast cancer. INTERVENTION:Breast density notification legislation, enacted in Connecticut in October of 2009. MAIN MEASURE:Breast cancer stage at diagnosis. KEY RESULTS:Our study included 466,930 women, 25,592 of whom lived in Connecticut. Legislation was associated with a 1.38-percentage-point (95 % CI 0.12 to 2.63) increase in the proportion of women in Connecticut versus control states who had localized invasive cancer at the time of diagnosis, and a 1.12-percentage-point (95 % CI -2.21 to -0.08) decline in the proportion of women with ductal carcinoma in situ at diagnosis. Breast density notification legislation was not associated with a change in the proportion of women in Connecticut versus control states with regional-stage (-0.09 percentage points, 95 % CI -1.01 to 1.02) or metastatic disease (-0.24, 95 % CI -0.75 to 0.28). County-level analyses and analyses limited to women younger than 50 found no statistically significant associations. LIMITATIONS:Single intervention state, limited follow-up, potential confounding from unobserved trends. CONCLUSIONS:Breast density notification legislation in Connecticut was associated with a small increase in the proportion of women diagnosed with localized invasive breast cancer in individual-level but not county-level analyses. Whether this finding reflects potentially beneficial early detection or potentially harmful overdiagnosis is not known. Legislation was not associated with changes in regional or metastatic disease.
