How common is ductal carcinoma in situ (DCIS)?

The American Cancer Society expects that 63,960 new cases of DCIS will be found in 2018. Today more and more women are aware of the importance of early detection and are getting mammograms each year. Because of this, the number of cases of DCIS has increased. In addition, mammography technology has greatly improved as well and is better able to detect problems at an earlier stage. An estimated 12.4% of women in the U.S. will develop invasive breast cancer at some time in their lives.
