Estimating Your Risk
The information in Disease Risk Index
is based on established science and proven risk factors.
A risk factor is proven if the evidence is strong enough
to show a link to the disease. The information applies to
populations in the US and other western countries.
Each question on the web site is
related to a number that represents the strength of the
association between the risk factor and the disease.
As you answer the questions, the numbers are multiplied
to equal your personal risk based on the risk factors
that apply to you. Your risk is then compared to the
average risk for a person your age and sex.
Disease Risk Index may not include
information on some things you think affect your risk
of cancer. That's because scientific studies don't show
a consistent link to the disease. If it's not included
in the web site, the Harvard Center for Cancer Prevention
doesn't regard it as a proven risk factor.
Disease Risk Index had it's beginnings
as the Harvard Cancer Risk Index, a pen and paper risk
assessment tool first put together in the mid 1990's by the
Index Working Group
at Harvard University.
Documentation of the process used to determine the content of
the site appears in the
Harvard Report on Cancer Prevention, Volume 4: Harvard Cancer Risk Index.
