Region of histological features of interest for invasive micropapillary cystic carcinoma as seen in conventional haematoxylin and eosin staining (a) and PhC \(\mu\)CT (b) with a pixel size of 4 μm. The images show the fibrous septum (FS), neoplastic micropapillae of ductal epithelium (green arrows), accumulation of packed red blood cells (blue stars), and basement membrane (red arrows), the latter being an important indicator of breast cancer progression. The scalebar is 0.5 mm.
