Comparing cancer site for selected geography


This tool presents the conversion rate and detection rate of urgent suspected cancer referrals, for England from 2009/10 onwards.

The results are presented for a choice of geography, allowing comparisons of the rates for different referral types/cancer sites and periods.

On the 'Tabular Data' tab, you can view and/or download the underlying data for your selections.


  • Urgent suspected cancer referrals (commonly known as two week wait referrals) are used to refer patients with possible cancer symptoms to secondary care for investigation and possible diagnosis.

  • Conversion rate is the percentage of urgent suspected cancer referrals which result in a diagnosis of cancer.

  • Detection rate is the percentage of cases recorded in the Cancer Waiting Times data as receiving a first treatment for cancer which resulted from an urgent suspected cancer referral.


Conversion and detection rates are provided for every financial year. Where this is not meaningful, the rates based on 3-year rolling average and denoted by the middle of the 3 years are provided instead. This means that no 3-year rolling average data is provided for the financial years at the start (2009/10) and end (2018/19) of the time series. However, there remain some instances where for the less common cancer site/referral type and smaller geography combinations the rates are not provided.
