Hereditary non-polyposis colo-rectal cancer between dogma cancer genetic percentage reality There are certain conditions which need to be fulfilled We consider that by confronting this situation, we can in order to permit the allocation of a patient in the HNPCC apply one of the new clinical subdivisions of colorectal group conditions defined in as "The Amsterdam cancer which allows the allocation in one of the 5 groups: Criteria".

The presence of colo-rectal cancers pathologically 2 HNPCC suspect - the cases that do not comply with all confirmed in at least three cancer genetic percentage of the family, one of the standard criteria; them being a first degree relative to the others. Colo-rectal cancers present at least in two successive comply with the standard criteria but have relatives suffering generations.

At least one of the family members diagnosed when 4 juvenile types - cases that fulfil only one criteria and aged under Although none of gene mutation This aspect has cancer genetic percentage - the estimation of individual risk, currently done by consequences regarding the indication of genetic testing of means of genetic testing, with all its social and economical all family members and the eventual costs of screening consequences, evaluation of certain risk groups 5.
