Seventy-four tumours corresponding to 37 patients were stratified into four groups based on the anatomic location of the multiple breast cancers (ipsilateral or bilateral) and time interval between the diagnoses (synchronous or metachronous). Ipsilateral was defined as tumours occurring in the same breast while bilateral was defined as the occurrence of tumours in both breasts. Metachronicity was defined as a time interval greater than six months between the diagnoses of the first and second tumours, while synchronicity specified that the two tumours occurred concurrently (BM: bilateral-metachronous; BS: bilateral-synchronous; IM: ipsilateral-metachronous; IS: ipsilateral-synchronous).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 sapiens[30092821]
