Abstract: A method based on image processing of tumoral neighbourhood is described for studying masses. By using polar and pseudopolar representations for the tumor and its neighbourhood, it is possible to detect divergent structures around the lesion and to evidence fuzzy areas in the boundary of the tumor, which constitute two significant features of breast cancer. The degree of spiculation is deduced from a shape parameter that characterizes the irregularity of the boundary; the radial component of the gradient on the boundary provides a measurement of fuzzy appearance.
