Welcome to the QCancer®(15yr,colorectal) risk calculator
Welcome to the QCancer-®(15yr,colorectal) web calculator. You can use this calculator to work out your risk of developing colorectal cancer by answering some simple questions.
This version of the calculator differs from the main QCancer®-10yr calculator in two ways.
First, the number of years that risk can be calculated over has been raised to 15 years.
Second, it is a cut down version of the main calculator, and presents the risk of developing colorectal cancer only.
The main QCancer®-10yr calculator, which shows the risk of developing several cancers over a 10 year period, is here.
The QCancer®-10yr algorithms have been developed by Julia Hippisley-Cox and Carol Coupland and are based on routinely collected data from many thousands of GPs across the country who have freely contributed data to the QResearch database for medical research.
QCancer®-10yr has been developed for the UK population, and is intended for use in the UK. All medical decisions need to be taken by a patient in consultation with their doctor. The authors and the sponsors accept no responsibility for clinical use or misuse of this score.
This colorectal cancer risk calculator was originally intended to show risk over a 1 to 10 year period, we have extended this to a 1 to 15 year period to inform a clinical practice guideline on colorectal cancer screening.
The science underpinning the QCancer®-10yr equations has been published in BMJ Open. See the publication page for a link.
