Towards More Realistic Biomechanical Modelling of Tumours under Mammographic Compressions

In this paper we present a biomechanical model of isolated breast tumours under mammographic compression forces. We apply a range of reported mechanical properties, both linear elastic and hyperelastic. We also introduce a volume of increased density/stiffness around the tumour. These variables have a non-negligible effect on stresses and strains, as shown in this work. © 2010 Springer-Verlag
