Dear Nancy52: Whether or not a lumpectomy or mastectomy is done depends upon several factors: Whether removal of adequate amounts of tissue (any cancer) will leave enough breast tissue to give a good cosmetic result; extent of disease; and choice. If a lumpectomy can be successfully done, radiation will be recommended. If a mastectomy is done, radiation may or may not be necessary depending on other findings. Staging should be discussed with your doctor. It is based on size of tumor and lymph nodes (and to some extent, the location of these nodes). So without reviewing the pathology and surgical report, we cannot comment on staging. Chemotherapy is often recommended in node positive disease but there are other factors that would be considered and should be discussed with your oncologist. Likely, endocrine therapy will be recommended at some point. How you will respond to therapy will depend upon the therapy that is given and your response to it (everyone is different).
