Dr Hayley Fenton


I am a Research Fellow in Epidemiology and Biostatistics. I am part of Prof Eva Morris’ Cancer Epidemiology Group within the Leeds Institute of Medical Research at St. James’s. Cancer Research UK are funding the creation of a UK colorectal cancer intelligence hub, which aims to bring together all of the datasets that are relevant to colorectal cancer in the UK to form a single accessible cancer data repository (CORECT-R). CORECT-R will be used by people across the country to produce the intelligence we need to improve outcomes from this common disease.

As part of the CORECT-R programme I analyse population-level, routinely collected data to investigate the treatment of advanced colorectal cancer. My preferred areas of research include the use of surgery and ablation to treat metastatic disease and treatment pathways for those with Stage IV disease.

I also work on data from the NIHR funded seAFOod Polyp Prevention and STOP-ADENOMA clinical trials on the use of EPA and Aspirin in prevention of colorectal polyps.


Previous and Current Roles

Prior to joining the group, I was a Data Scientist in the Leeds Institute for Quality Healthcare providing data intelligence across several professional leadership and change project teams. I worked with NHS partner organisations and Leeds City Council with the aim of improving patient care across Leeds in areas such as diabetes, cancer and cardiovascular disease. My support enabled the teams to successfully bid for £600,000 of NHS England funding to continue their improvement work. Part of my role was to present complex analysis to NHS staff, from Chief Executives to Health Care Assistants.

I have also previously worked in the Civil Service providing analysis around healthcare costs and tariff development, and I provided analytical support around State Pension age and demography towards the Pensions Act 2014, briefing to the Minister for Pensions on a regular basis and rapidly turning around pre-release statistics.
