1526 Background: In women with a family history (FH) of breast cancer the risk can be substantially increased and starts at an earlier age compared with the general population. Women with FH of breast cancer are not suggested oncogenetic counselling unless the subject is brought up in the contact with medical professionals. Consequently, a woman with FH for breast cancer has to have knowledge about the possibility of counselling to come into question for information, advice and special surveillance program. The aim of this study was to characterize women at an oncogenetic counselling clinic in terms of socioeconomic status (SES) and to compare these data with population based figures from the same catchment area. Methods: All healthy women who had, once or repeatedly, been visiting the oncogenetic clinic at the Department of Oncology, Karolinska University Hospital / Sodersjukhuset, between April, 1998 - June, 2004 were eligible for study. A total of 307 out of 378 consecutive women consented to participate (81%) in the survey by returning mailed questionnaires. SES data were compared with official data for all women aged 24 -75 year from the same catchment area (n= 277 783 women). Results: See table . Conclusions: Women visiting the oncogenetic counselling clinic were higher educated, more often married and had a better economic situation than comparable women from the same catchment area. These findings indicate that efforts should be elaborated to increase the knowledge about the possibility of genetic counselling among women with FH for breast cancers.
