Conclusion
Aujourd’hui, dans certaines situations familiales bien documentées et sévères, des tests génétiques sont proposés. Leurs enjeux principaux sont de rassurer les apparentées non prédisposées, et, pour les apparentées prédisposées, de mettre en route une surveillance mammaire dès l’âge de 30 ans, voire dès 25 ans, et de recommander une chirurgie ovarienne prophylactique à 40 ou 50 ans en fonction du contexte.
Deux défis restent à relever : l’identification de nouveaux gènes de prédisposition et la caractérisation d’éventuelles interactions entre le risque familial et les risques hormonaux. Dans les deux cas, ces connaissances permettront d’être plus précis dans l’estimation des risques individuels. Enfin, devant le doublement de l’incidence des cancers du sein au cours de ces trente dernières années, il est crucial de repérer les facteurs qui, liés à notre mode de vie, ont un impact si important sur la population générale et probablement aussi sur les femmes prédisposées.
