Breast screening and ethnic minorities

Area of Science:

• Public Health
• Oncology
• Health Disparities

Background:

• Breast cancer incidence varies globally, with lower rates in some Asian and Middle Eastern populations compared to the UK.
• Minority ethnic women are not typically a high-risk group, but breast cancer remains a significant health issue.
• Ethnic differences in screening uptake are understudied and potentially confounded by socioeconomic factors.

Purpose of the Study:

• To investigate potential disadvantages faced by minority ethnic women regarding breast cancer incidence and screening program uptake.
• To identify barriers and evaluate strategies for improving screening participation among diverse populations.

Main Methods:

• Review of existing literature on ethnic variations in breast cancer incidence and screening uptake.
• Analysis of factors influencing non-attendance, including socioeconomic status, registration accuracy, and cultural understanding.
• Evaluation of a randomized controlled trial for a linkworker intervention aimed at increasing breast screening uptake in Asian women.

Main Results:

• Socioeconomic factors can confound ethnic differences in screening uptake; Asian women's uptake may not be lower than others when adjusted, and Black women's uptake can be higher than White women's.
• Inaccurate screening registers and issues with understanding invitations due to naming systems are significant organizational barriers.
• A linkworker intervention trial showed no increase in breast screening uptake among Asian women.

Conclusions:

• Addressing organizational issues like accurate registers and improving comprehension of screening are crucial.
• While linkworkers may not be effective for increasing screening uptake, their role can be repurposed.
• Further assessment of reasons for low uptake and targeted interventions are essential for equitable resource allocation and meeting unmet needs in breast cancer screening.
