Dear 1katz: Lobulations are not calcifications. Lobulations describes the appearance of being rounded - like a small cluster of grapes. Indistinct contour refers to the appearance of the nodule not having as clear an edge on the film. In other words, the edge may appear fuzzy or difficult to see. Margins usually refer to the edges of a surgical/pathology sample. Stereotactic biopsies are usually done within the radiology department. Depending on the type of stereotactic biopsy, a surgeon may be involved as well. The length of time for results and the method of delivery will depend upon the institution that performs the biopsy. Most results will take about a week. Method of delivery will vary. If the biopsy shows cancer, it is an unlikely explanation for the fuo and elevated white count.
lobulations are not calcifications: they are shapes that are rounded and repeated, like the contour of cauliflower. Slightly indistinct would not necessarily mean "no" clear margins (first of all, "clear margins" most often refers to the pathological exam of removed tissue; it indicates whether the edges of the tissues removed do or do not have cancer cells in them). "Distinct margins" or some similar term is used to describe xray shadows: shadows which have very sharp, like a pencil drew them, edges are less likely to be cancer than ones that have fuzzy margins. "Slightly indistinct" sounds fairly equivocal, and not definitive information. Most stereotactic biopsies are done by a radiologist: it's a technique where you lie on your belly, the breast is xrayed and by xray guidance a needle is inserted into the area. The report timing varies a lot from community to community: it could be within 24 hours or a few days. The report would usually go to the doctor who ordered the test (your doctor) and it would be up to that doctor, not the radiologist, to tell you the results. Whether by phone or in person would depend on the practice of that particular doctor; you could tell him/her what you'd prefer. Unless you had a large tumor which had dead tissue in the center, it' highly unlikely breast cancer would cause FUO or elevated white count.
