Hi Krissy: First, please read our IDC FAQS, to acquaint yourself fully with this diagnosis. The first step in treatment is usually either surgery to remove the tumor; or chemo to shrink the tumor. That said, there's often quite a lag between diagnosis and onset of treatment, sometimes up to 6 weeks or so. Various doctors/surgeons need to be scheduled, and it doesn't always fall into place quickly. Following surgery, your mother would probably have chemo (if she hasn't already); and possibly radiation, depending on the pathology of the tumor, where it was located, etc. Then, she might take hormone drugs. This is a pretty typical course of treatment. Hope this helps. Good luck - PJH
