Technically metastatic cancer is not curable. But there are treatments that can help (but not cure). To me, a lay person, it looks like the cancer is in the breast (inflammatory) and bones, but not the lymph nodes or organs (which is good). But the oncologist should read and explain these to you. I am not qualified. However, as a past breast cancer patient I just want to offer support as you and your wife go through this with the help of oncologists. You can be direct as you like with your questions to them and they need to give you all the information you need going forward.
