What is the prognosis for patients who have ductal carcinoma in situ (DCIS)?

Because DCIS is contained within a specific area of the breast and has not spread, the disease can be controlled and cured with appropriate treatment. After treatment, the outcome for the patient with DCIS is usually excellent.

However, those patients who have had DCIS, even if treated successfully, are at a greater risk than people who have never had breast cancer to have the cancer return or for another type of breast cancer to develop.
