[Usefulness of the oncogenetic molecular counselling in adults whith familial cancer]

More than 200 cancer susceptibility syndromes (CSS) have been recognized through performing classic epidemiologic studies and genetic linkage analysis. In most CSSs clinical conditions of the patients have been identified as well as their hereditary patterns and the predisponent genes to cancer development. Cancer hereditary identification is a useful condition, since cancer family integrants may benefit of efficient strategies in early screening and in tumor prevention strategies; this consultation is performed by oncogenetic molecular medical consultants who must be scientifically competent for Human Genetics and Cancer molecular biology domains. The oncogenetic molecular consult of patients and family relatives of cancer predisposition families is a medical service in health programs of developed and developing countries; in our country this type of medical service needs to be organized and settled to be part of the integral oncology medical service. The oncogenetic molecular consultation is a structural process of assessment and communication of the associated integral problems of the cancer inherited susceptibility in familial cancer.
