> Risk of Developing Invasive Cancer after Ductal Carcinoma in Situ
After treatment for ductal carcinoma in situ (DCIS), there is still a chance invasive breast cancer could develop. This risk is higher with lumpectomy (also called breast conserving surgery) plus radiation than with mastectomy. A meta-analysis that combined the results of 21 studies found the risk of invasive cancer was about nine percent following lumpectomy plus radiation and 1.4 percent following mastectomy [84].
Despite these differences, survival is the same after either treatment [84]. With close follow-up, invasive breast cancer is usually caught early and can be treated successfully.
