Jax, Hi, Hon, and welcome to the group. I am sorry that you have had to join us but if you had to join a support group this is one of the best.
I don't want to scare you but I would rather you be as informed as possible rather then not, and of course your story may be, and hopefully will be, very different then mine.
I was diagnosed with microcalcifications non-invasive DCIS in March of 2004. I too had a stereotactic biopsy and was grade 3 but I was ER PR positive . They didn't remove any sentinel nodes (wish they had). I had a lumpectomy and radiation and even had a second lumpectomy to recheck the margins which came back clean. I was assured that by 99.9% that they had gotten it all and that I was cancer free. Well, in December 2006 I had a gallbladder attack and went in to have it removed and when they went in they found cancer spread throughout my liver. I also have two spots on my spine and I am HER2 positive but the metastatic cancer to the liver is ER PR negative. I am currently on a clinical trial of Herceptin, Taxol and Lapatinib and receive Zometa once a month as a bone strengthener. Perhaps if they had removed the sentinel nodes I wouldn't be in this stage now, stage 4, but the onc says even if they had removed any sentinel nodes that they probably at that time would have come back clean and may still be clean. They seem to think that it traveled through my blood stream as opposed to the lymphatic system.
If I were you I would definitely push for some type of therapy other then just radiation, but that is just my opinion for what it is worth.
Here is a great article to read on DCIS called "Is it really DCIS?" I wish you all the very best, please keep us informed on how you are doing and what your treatment plan will be.
