Ductal Carcinoma In-Situ: An Editorial

Kelly Lambert and Kefah Mokbel

Ductal carcinoma in-situ (DCIS) is an increasingly common pre-invasive form of breast-cancer. 27% of all new breast cancer diagnoses in 2008 in the United States were DCIS as opposed to less that 1% before the introduction of national mammographic screening programmes. It is probably the pre-cursor of most invasive breast-cancer but not all DCIS will progress to this stage. So the challenge in the modern treatment of DCIS is to avoid over-treatment.
