Cancer Growing In Pancreatic Duct (IMAGE) The Francis Crick Institute Caption The image shows cancer growing inside the pancreatic duct of a mouse. It was obtained using a new technique to study 3D tissue samples, revealing that cancers can begin as 'endophytic' tumours which grow into the ducts (shown here) or 'exophytic' tumours growing outwards.
