Question: Are in situ and invasive breast cancers treated differently?
Answer: In situ cancers and invasive cancers often are treated in the same way but for different reasons. After all, we don't have too many options. We can save the breast, we can save the breast and then radiate it or we can do mastectomies. And in selected circumstances, each of these treatments is applicable to patients with in situ cancers and with invasive cancers. What is most important is trying to discriminate among the different types of in situ cancers and the types of invasive cancers so that we can make the right recommendation for the right reasons to the right patients.
