^aDiagnosed at the same time as breast cancer

^bFifteen women did not report age at menopause but were older than 60 years at the end of follow-up

^cInformation from questionnaire and record linkage

^dAge last known to be premenopausal: mean 32.3 years, median 31 years for BRCA1 mutation carriers: mean 33.9, median 34 years for BRCA2 mutation carriers. Time between this age and end of censoring: mean 6.3, median 5 years for BRCA1 and mean 6 years, median 5 years for BRCA2 mutation carriers

^eSeven women reported RRSO after age 60 years without first reporting natural menopause
