Array-based genome-wide transcriptome analysis of Ductal carcinoma in situ (DCIS). Array-based genome-wide transcriptome analysis of Ductal carcinoma in situ (DCIS)

Ductal carcinoma in situ (DCIS) is the presence of abnormal cells inside a milk duct in the breast. DCIS is considered the earliest form of breast cancer. DCIS is noninvasive, meaning that it does not spread out of the milk duct and has a low risk of becoming invasive. Overall design: The tumorous and non-tumorous regions of mammary gland specimens from 3 DCIS patients.
