Your Disease Risk
Encyclopedia
Your Disease Risk is a publicly available health risk assessment
tool on the Internet. Launched in early 2000 and continually updated, the site offers risk assessments for twelve different cancers and four other important chronic diseases: heart disease, stroke, diabetes, and osteoporosis.
The site began in 1998 as a pen and paper questionnaire called the Harvard Cancer Risk Index. In January 2000, The Harvard Cancer Risk Index developed into an online assessment and was renamed Your Cancer Risk, and offered assessments for four cancers: breast, colon, lung, and prostate. Six months later, eight additional cancers were added.
In 2004, the site was renamed Your Disease Risk to reflect the addition of four further conditions: heart disease, stroke, diabetes, and osteoporosis. Since many common chronic diseases share risk factors, the renaming promoted the importance of a healthy lifestyle to lowering disease risks.
In 2007, the site moved to the Alvin J. Siteman Cancer Center at Washington University School of Medicine.
A validation study found Your Disease Risk to provide well calibrated estimates of cancer risk in the general population. For individual women, the discriminatory accuracy for colon cancer was 0.67, for ovarian cancer 0.59, and for pancreatic cancer was 0.71. For individual men, the discriminatory accuracy for colon cancer was 0.71 and for pancreatic cancer was 0.72. These values exceed the performance of many other cancer risk prediction tools.
The approach used to calculate cancer risks in Your Disease Risk is also used to calculate the risks of the other diseases. Validation studies for these non-cancer estimates are ongoing.
Health risk assessment
A health risk assessment is one of the most widely used screening tools in the field of health promotion and is often the first step in multi-component health promotion programs....

User Experience
Your Disease Risk has a simple, straightforward interface. Questionnaires can be completed in a matter of minutes, and for each disease, the site offers both a visual and verbal risk estimate as well as personalized tips for prevention. The site can also show users what their risk could be should they adopt various healthy behaviors. Tailored screening tips and recommendations for making health changes in communities are also part of site results.Methodology
The calculations and algorithms used to calculate and display risk estimates in Your Disease Risk are the product of an ongoing process of expert consensus. Epidemiologists, clinicians, and other health specialists regularly review the current scientific evidence for each disease, identifying established and probable risk factors for each. This information is then used to develop or revise calculations that generate a user’s risk of disease compared to average risk in the population for someone of the same age and sex.A validation study found Your Disease Risk to provide well calibrated estimates of cancer risk in the general population.
