> Risk of Developing Invasive 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 than with mastectomy. However, survival is the same after either treatment . With close follow-up, invasive breast cancer is usually caught early and can be treated successfully.
