People from minority ethnic and deprived backgrounds in England are up to a third less likely to be diagnosed with breast cancer through routine screening, and more likely to be diagnosed in an emergency setting, analysis has found.
The research, by academics at the University of Surrey and funded by the charity Breast Cancer Now, examined 86,564 adults diagnosed with the disease between 2009 and 2019, drawing on the Clinical Practice Research Datalink and the Cancer Registration Tumour and Treatment datasets.
It found that people from Black, Asian and mixed backgrounds, alongside people from deprived backgrounds, were up to 33% less likely to be diagnosed via screening. These groups were up to 31% more likely to be diagnosed through an urgent suspected cancer referral, and up to 37% more likely to be diagnosed via emergency presentation.
Manveet Basra, associate director of public health, inclusion and awareness at Breast Cancer Now, said the analysis showed people from marginalised groups "face inequalities at every stage of their breast cancer experience, and tragically this impacts their survival rates." She described the charity as determined to improve breast cancer care and outcomes, working with policymakers to improve equal access to screening, and ensuring its information, campaigns and support services reflect the diverse needs of everyone affected by the disease.
The research also found that people with a learning disability had poorer outcomes: their time to diagnosis was 18% longer than for people without a learning disability, and they faced a 10% longer wait for treatment.
The findings add to earlier evidence of unequal outcomes. A previous analysis found that about one in three people from ethnic minority backgrounds required three or more GP interactions before a cancer diagnosis, compared with one in five people across England, based on the NHS cancer patient experience 2022 survey. Research from the UK Health Security Agency has also suggested that young black women are more likely to have aggressive breast cancer tumours, experience poorer care and have higher mortality rates, while being significantly under-represented in clinical research.
Dr Rob Kerrison, associate professor of cancer care at the University of Surrey and the study's lead investigator, said: "We know that some groups of women in the UK have poorer breast cancer survival than others, but until now we have had only a limited understanding of why. Our findings suggest that inequalities in access to screening and timely treatment may be part of the explanation. If we are serious about improving breast cancer outcomes, we need to ensure that everyone can access screening and receive prompt treatment, regardless of their background or circumstances."
