Background Many cancer-patients undergo DNA testing in the BRCA1/2 genes to receive information about the likelihood that cancer is heritable. Previous nonsystematic studies suggested that DNA testing often does not fulfill the counselees' needs for certainty. We explored the balance between the counselees' need for certainty and perceived certainty (NfC-PC, i.e., level of fulfillment of NfC) regarding the specific domains of DNA test result, heredity and cancer. We also examined relationships of NfC-PC with coping styles and distress. Method Before disclosure of BRCA1/2 test results for hereditary breast/ovarian cancer (T1), questionnaires were filled in by 467 cancer-patients. Another questionnaire (T2) was filled in after disclosure of pathogenic mutation results (n=30), uninformative results (n=202) or unclassified-variants (n=16). Results Before and after DNA test result disclosure, overall 5894% of all counselees experienced unfulfilled NfC regarding the DNA test result, heredity and cancer. Compared with T1, the communication of pathogenic mutations (T2) caused more fulfillment of the NfC about the DNA test result, but less about cancer and heredity (pPC). Compared with T1, uninformative results (T2) caused more fulfillments of all needs than before disclosure (p
