Research suggests coffee not associated with breast cancer risk

25 January 2021

A recent study published in PLOS ONE found that genetically predicted coffee consumption is not associated with breast cancer risk. MRC IEU researchers Prof Richard Martin and Dr Sarah J Lewis contributed to the research.

The researchers carried out two-sample Mendelian randomisation analyses on genes associated with coffee consumption for more than 200,000 female participants in the UK Biobank. They also drew on data from over 100,000 women in the Breast Cancer Association Consortium.

Whilst the results of this study show no association between coffee consumption and breast cancer risk, the researchers caution that such a link cannot be ruled out.  

The research was led by Merete Ellingjord-Dale of the Department of Epidemiology and Biostatistics, School of Public Health, Imperial College London, London.
