NIH to Hold Press Telebriefing on September 24 following State-of-the-Science Conference on Ductal carcinoma in situ

Panel will assess evidence on the most common noninvasive tumor of the breast.

What: Ductal carcinoma in situ (DCIS) is a condition in which abnormal cells are found in the lining of a breast duct. Although the natural course of DCIS is not well understood, this intraductal carcinoma can become invasive cancer and spread to other tissues. However, not all DCIS will progress to invasive disease, and it is thought that DCIS can be present in some individuals without causing problems over a long period. Unfortunately, it is currently not clear which lesion types are more likely to become invasive. There is also still uncertainly regarding the most effective treatment modality and how this may vary by specific tumor and patient characteristics, leading to difficult decisions for patients and providers. 

After weighing the evidence from a systematic literature review, expert presentations, and audience input, an impartial, independent panel will hold a press telebriefing, which will highlight the findings from their statement and their implications to the public.

Who: Members of the State-of-the-Science Conference panel, to be announced Tuesday, September 22.
