A set of BC [36] FISH data consisting of  paired (from the same patient) ductal carcinoma in situ (DCIS) and invasive ductal breast carcinoma (IDC) samples with  cells per sample profiled on eight FISH probes: COX-2 (5743) [59], MYC (4609) [60], CCND1[58], HER-2 (2064) [61], ZNF217 (7764) [62], DBC2 (23221) [63], CDH1 (999) [64] and TP53 (7157) [65]. This evidence concerns the gene CDH1 and invasive ductal breast carcinoma.
