​Please could you provide data about the incidence of breast cancer in women taking hormone replacement therapy (HRT) with those that are not taking HRT within 10 years.

We said

Thank you for your enquiry.

We do not hold data relating to incidence of cancer in the UK.

ONS were responsible for cancer incidence statistics in England up to 2017 when NHS Digital took responsibility for this work, however this does not include information on whether hormone replacement therapy (HRT) was taken: Cancer registration statistics, England.

NHS digital would be better placed to answer your enquiry. They can be contacted on
