The objectives of this study were to: (1) describe diffusion of information by affected women in whom a mutation has been identified (index cases) to their families and testing participation among high-risk relatives; (2) assess information recall and understanding by index cases and their satisfaction with the testing process; and (3) determine the factors associated with higher/lower testing decision in the family. Thirty index cases completed a self-administered questionnaire assessing their personal and family characteristics and their satisfaction with their own genetic testing process and a telephone interview to evaluate their knowledge about the risk of a genetic predisposition to breast and ovarian cancer, the type and number of close relatives that they informed, and the difficulties that they encountered. Information about breast/ovarian cancer risk and test availability was generally well transmitted (75%), predominantly (88%) to first-degree relatives. In contrast, testing participation was low (15%) and essentially occurred among sisters and daughters. There was a general lack of knowledge despite a high level of satisfaction regarding the information given by the geneticist. Family support and the knowledge of index cases about the risk of transmission of BRCA1/2 mutations by women were found to be positively and significantly associated with the testing decision among first-degree relatives. Difficulties in informing relatives appeared to be related to poor understanding of the information by index cases, as well as fear, and avoidance among close relatives. A major challenge for genetic counseling is to ensure that consulting patients not only receive complete understanding but also understand this information and anticipate the impact of the test result before deciding to take the test.

Our results confirm the potentially negative impact of the knowledge of the genetic risk of cancer and its consequences in terms of morbidity and follow-up, on the QoL in people followed at oncogenetic visits.

The aim of this case report is to show that hemochromatosis can present, unusually, with night sweats. At presentation, hemochromatosis often tends to have non-specific symptoms, making it easy to misdiagnose, especially if it presents with rare symptoms. Misdiagnosis of hemochromatosis can lead to lethal outcomes, given it can cause multiple organ dysfunctions if left untreated and hence the need to identify it early on. The case we present is a 41-year-old woman with previously undiagnosed hemochromatosis complaining of night sweats. She thought she was menopausal. The diagnosis of hemochromatosis was made solely on investigations given that she did not have any other symptoms other than night sweats. Her serum iron concentrations were within the normal range due to menstruation. It is uncommon for women to present with symptoms of hemochromatosis during their reproductive life since their iron concentration is kept within normal range through monthly menstrual bleeding.
