Introduction: African American women experience a disproportionate burden of breast cancer morbidity and mortality. For African American breast cancer survivors, members of their social networks often act as informal caregivers - offering social support and assisting with treatment adherence. They may thus serve as opinion leaders within their own social networks, given their personal experiences with the breast cancer survivor. Nonetheless, informal caregivers are not formally trained and may be vulnerable to breast cancer cultural beliefs and fear related to breast cancer. For this study, we examined: 1) if informal caregivers’ breast cancer cultural beliefs and fear were predictive of breast cancer misinformation shared among their social networks and, 2) if misinformation shared led to lower mammogram uptake among their networks. Methods: This is a secondary analysis of the Offering African Survivors Increased Support (OASIS) study, which assessed African American breast cancer survivors’ experiences with cancer care. To be eligible, subjects had to be: 1) identified as an informal caregiver by a survivor, 2) female, and, 3) of breast cancer screening age (50-74 years). Recruitment took place from Feb 2019 – Mar 2020. Subjects took part in 60-90 minute in-person or telephone surveys and received an incentive for participation. Validated scales were used in the survey tool to quantify cultural beliefs and fear, spread of breast cancer misinformation, and mammogram uptake. Results: 142 informal caregivers were recruited. All were African American, 56% were 50-62 years of age, 95% had a primary care provider, and 82% had a mammogram in the past year. Overall, 65% reported ≥1 breast cancer cultural belief and all reported breast cancer fear. On average, informal caregivers reported 1.55 (range: 0-15) cultural beliefs and a moderate level of fear (score=19.72, 8-32). 18.3% of informal caregivers shared breast cancer misinformation to their networks. Informal caregivers who reported ≥1 cultural belief had 74% greater odds of sharing misinformation to their networks (OR=1.74, 95%CI [1.32, 2.29], p<.0001). Among the 341 social network members of informal caregivers who were women and 50-74 years of age, those who received misinformation were 63% less likely to obtain a mammogram (OR=0.37, 95%CI [0.14, 0.94], p=0.04). Conclusion: Informal caregivers who reported breast cancer cultural beliefs were significantly more likely to share breast cancer misinformation to their social networks and social network members who received this misinformation were significantly less likely to receive mammograms. These results may inform planning for health education efforts and community-healthcare interventions that address breast cancer cultural beliefs and promote mammogram uptake among African American women. Future research will assess key themes in breast cancer misinformation shared and differences in misinformation shared from informal caregivers to their networks based on relationship type.

Introduction: African American women experience a disproportionate burden of breast cancer morbidity and mortality. Members of African American breast cancer survivors’ social networks often act as informal caregivers, offering psychosocial support, sharing important information, and assisting with treatment adherence. They may thus serve as opinion leaders within their own social networks, especially if they are also women and are within the recommended age for breast cancer screening. Nonetheless, informal caregivers are not formally trained and may be vulnerable to cultural misconceptions and higher levels of fear through their firsthand experiences as caregivers. Understanding the relationship between breast cancer cultural misconceptions, fear and the spread of misinformation among the social networks is crucial; yet, little research has been done in this area. Methods: This is a secondary analysis of the Offering African Survivors Increased Support (OASIS) study, which assesses African American breast cancer survivors’ experiences with cancer care. To be eligible, participants had to be: 1) identified as a support person by a survivor; 2) female; and, 3) 50-74 years old. We used the validated Ferrans Cultural Beliefs and Champion Breast Cancer Fear scales to quantify cultural misconceptions and fear retrospectively. For social network dissemination, we used a modified Burt’s General Social Survey instrument and coded open-ended fields regarding communication between caregivers and up to 5 network caregivers. Results: 30 informal caregivers were surveyed. Sixty percent reported at least one cultural misconception, the most common misconception being “If breast cancer is cut open in surgery, it will grow faster.” Approximately 33% further disseminated cultural misconceptions to 2 or more people within their networks. After adjusting for education, our multivariable linear regression suggested that informal caregivers who report greater breast cancer fear (Std B = 0.46, p = .008) and more misconceptions (Std B = 0.44, p = .02) disseminated cultural misconceptions to more people within their network. Conclusion: Informal caregivers that reported greater misconceptions and fear related to breast cancer were significantly more likely to share breast cancer misinformation to their social networks. These results show the value of initiatives in clinical and community settings that address these misconceptions and support increased breast cancer screening. Future research will assess the specific recipients of miscommunication (e.g., family, friends) and how this miscommunication is associated with the likelihood of obtaining breast cancer screening among their networks.
