<i>Background:</i> The Magnetic Resonance Imaging Screening study evaluates the efficacy and psychological impact of a surveillance program for women at increased risk for hereditary or familial breast cancer in the Netherlands. Surveillance consists of biannual physical examination, annual mammography, annual MRI and monthly breast self-examination (BSE). <i>Objective:</i> To examine the association between psychological distress and reported BSE frequency. <i>Methods:</i> Two months prior to surveillance demographics, BSE frequency, general distress (Hospital Anxiety and Depression Scale and the somatic scale of the Symptom Checklist-90) and breast cancer-specific distress (Impact of Event Scale) were assessed in 316 women (mean age 40.5 years, range 21–63 years). <i>Results:</i> The majority (57%) reported performing monthly BSE. Ten percent reported never performing BSE, 20% less frequently than once a month and 13% at least once a week. Women below the age of 40 who examined their breasts more frequently than recommended (i.e. at least once a week) were shown to be significantly more distressed than the other women in the sample (p = 0.03). These women represented 15% of all the women below the age of 40 years in our study sample. <i>Conclusion:</i> Higher breast cancer-specific distress scores were observed among younger women who examined their breasts at least once a week. It is important for physicians to be aware of this hypervigilant behaviour, especially since it is correlated with breast cancer-specific distress.
