Eighty-four @entity1 included in the @entity16850 Registry were reviewed. The age of diagnosis ranged from 10-44 years (mean, 21). Sixty-nine percent of @entity1 were less than or equal to 20 years of age. The left breast was affected slightly more often (52%) than the right (48%) when the lesion was unilateral. Two @entity1 had bilateral lesions. Patterns of menarche, marital history, parity, and use of birth control pills were not exceptional for @entity1 in this age group. No instance was found of maternal use of @entity172 during pregnancy. There were no instances of @entity189 developing after biopsy of @entity16850 , but a newly diagnosed @entity1 had @entity189 arising from @entity16850 . Two other examples of concurrent @entity189 were previously reported ( @entity1137 in situ and contralateral @entity189 ). Particularly noteworthy is the finding that 26% of @entity1 wih information available reported that @entity0 had occurred in one or more female relatives. The major were older, secondary relatives (grandmothers, great aunts), although @entity0 (five cass) was also reported. The mothers of both @entity1 who had @entity189 associated with @entity16850 had been treated for @entity0 . These findings, based on incomplete reporting, are cause for concern in two respects: the findings suggest that @entity16850 may be a marker for @entity0 for the @entity1 's family, and they indicate a need for continued long-term follow-up of @entity16850 @entity1 who may themselves be at increased risk.
