title: [The problem of multiple breast cancers (author's transl)].
abstract: This retrospective study is based on the appearance of bilateral breast cancers -- occurring simultaneously or succeedingly -- in patients our therapeutical radiation section. The examination of 368 patients in the years 1978-1981 gave result of 12 cases (3,2%) showing simultaneous bilateral breast cancer and of 14 cases (3,8%) showing succeeding contralateral breast cancer. Therefore multiple breast cancers are not to be regarded as a limited process but as manifestation in a cancerogenic effective range. This is of prime importance to the diagnosis and therapy of breast cancer.
