> Risk of Developing Invasive Breast Cancer after Ductal Carcinoma in Situ
After treatment for ductal carcinoma in situ (DCIS) there is still a small chance DCIS could recur (return) or invasive breast cancer could develop. These risks are higher with lumpectomy (also called breast conserving surgery) plus radiation therapy than with mastectomy .
However, overall survival is the same after either treatment [2,11]. With close follow-up, invasive breast cancer is usually caught early and can be treated successfully.
