Dear mazami: The question in this situation is whether the cells in the FNA were representative of the
lumpLumps in the breasts. In other words, did the biopsy include enough cells to get a representative sample of the
lumpLumps in the breasts. The other question is whether this is the same lump or whether there is something about it that changed or is it a different lump. A malignant cell is a cell that has mutated or changed over time in such a way that it no longer has the properties of a benign cell.
