Invasive ductal carcinoma (IDC) accounts for approximately 70 percent of all breast cancers. These cancer cells form in the lining of
the milk duct and then break through the ductal wall and invade nearby breast tissue. The cancer cells may remain localized — staying near the site of origin — or spread (metastasize) throughout your body, carried by your bloodstream or lymphatic system. The graphic shown below is of a normal breast with invasive ductal carcinoma, in the enlarged cross–section of the duct.
