Welcome to the QCancer®-2014 site.
This website is primarily intended for doctors and nurses working in general practice and for academics who are interest in the underlying research. Patients are welcome to read this information and use the calculator together with their doctor so that any symptoms or concerns can be addressed within a health care setting. 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.
QCancer® works out the risk of a patient having a current but as yet undiagnosed cancer taking account of their risk factors and current symptoms. It does not give a diagnosis cancer, but a risk.
The QCancer® 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® has been developed for the UK population, and is intended for use in the UK.
The science underpinning the new QCancer®-2013 equations has been published in January 2013 edition of the BJGP. The algorithms are updated and recalibrated anually, and this site implements the 2014 update.
There are two calculators, one for men and one for women:The QCancer® scores:

For background to this product, please see Macmillan's web site.
The QCancer® scores within this BMJ-Informatica product have been calculated using ClinRisk's QCancer® software development kit. However, the initial Macmillan pilot for which this software was developed centred on particular tumour sites. For each of those sites, the BMJ-Informatica product uses symptoms particularly correlated with those sites, rather than the full set of symptoms used by ClinRisk's qcancer.org web site, which takes a whole person, multi-tumour site approach. This explains any difference between the scores presented here, and those on qcancer.org, which has the patient's true QCancer® score.
Please note that the Macmillan CDS tool is primarily based around the subset of the tumour sites available in QCancer® which is shares with Willie Hamilton's eRAT risk tools. We understand that the tool now incorporates a "whole patient" screen similar to that provided here at qcancer.org, but that the other tumour sites do not feature in the decision support section of the main software. We hope that a future release of this Macmillan CDS tool will support all of the QCancer® tumour sites in due course.
