Our objective was to evaluate the sociodemographic variables, family history of cancer, breast cancer (BC) screening practices and the risk profile of cancer affected or asymptomatic at\u2010risk women that undergo genetic counseling for hereditary breast cancer in public Brazilian cancer genetics services. Estimated lifetime risk of BC was calculated for asymptomatic women using the Gail and Claus models. The majority of women showed a moderate lifetime risk of developing BC, with an average risk of 19.7% and 19.9% by the Gail and Claus models, respectively. The average prior probability of carrying a <jats:italic>BRCA1\/2<\/jats:italic> gene mutation was 16.7% and overall only 32% fulfilled criteria for a hereditary breast cancer syndrome as assessed by family history. We conclude that a significant number of individuals at high\u2010risk for HBC syndromes may not have access to the benefits of cancer genetic counseling in these centers. Contributing factors may include insufficient training of healthcare professionals, disinformation of cancer patients; difficult access to genetic testing and\/or resistance in seeking such services. The identification and understanding of these barriers is essential to develop specific strategies to effectively achieve cancer risk reduction in this and other countries were clinical cancer genetics is not yet fully established.<\/jats:p>","DOI":"10.1007\/s10897-006-9073-0","type":"journal-article","created":{"date-parts":[[2007,2,23]],"date-time":"2007-02-23T03:27:08Z","timestamp":1172201228000},"page":"363-371","source":"Crossref","is-referenced-by-count":19,"title":["Clinical Characterization and Risk Profile of Individuals Seeking Genetic Counseling for Hereditary Breast Cancer in Brazil"],"prefix":"10.1002","volume":"16","author":[{"given":"Edenir Inez","family":"Palmero","sequence":"first","affiliation":[{"name":"Postgraduate Program in Genetics and Molecular Biology Federal University of Rio Grande do Sul (UFRGS) Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia","family":"Ashton\u2010Prolla","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Genetics and Molecular Biology Federal University of Rio Grande do Sul (UFRGS) Porto Alegre Brazil"},{"name":"Department of Genetics UFRGS Porto Alegre Brazil"},{"name":"Medical Genetics Service Hospital de Cl\u00ednicas de Porto Alegre Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Cl\u00e1udio C.","family":"da Rocha","sequence":"additional","affiliation":[{"name":"Department of Oncogenetics Hospital do Cancer A.C.
