Chaos and fractals in medicine [s.1]

I am interested in the application of chaos and fractals to medicine. There are a number of promising applications of fractal dimension estimations for early prognosis of certain diseases. Examples range from tumor growth to diabetes. For the later, it is possible to apply non-invasive techniques to detect tendencies to develop diabetes. The idea is based on the observation that diabetic patients develop a more complex network of blood vessel on the retina due to a change on the blood's viscosity. From a retinal scan image one can estimate the complexity of the blood vessel network by measuring its fractal dimension. Then, by comparing this measure to test group statistics, it should be possible to assess, at some degree, the level of diabetes risk of a particular individual.
