What Do You Know About the Most Common Breast Cancer Diagnosis: Infiltrating Ductal Carcinoma?

(0 out of 1) Incorrect! No, they're actually different terms for the same diagnosis. "Infiltrating" and "invasive" mean exactly the same thing: that cancer cells have broken out of the area of your breast where they began to grow, and have moved into surrounding breast tissue. This is what distinguishes IDC (or any kind of "invasive" or "infiltrating" breast cancer) from non-invasive breast cancer: DCIS (ductal carcinoma in situ) or LCIS (lobular carcinoma in situ).Invasive breast cancer is actually an umbrella term for a number of different types of invasive cancers, including IDC; ILC (invasive lobular); IBC (inflammatory); Paget's disease (nipple cancer); and a number of other, rarer types. So, IDC IS invasive breast cancer; but invasive breast cancer isn't necessarily IDC.   Continue Quiz >
