Fractal analysis was used to study differences between cancer cells and normal cells. The complexity of cancer cells was found to be lower than that of normal cells. Fractal geometry helps measure irregular shapes, like clouds or coastlines, using a value called the fractal dimension. This method can be used to distinguish between different types of objects. In cancer research, fractal analysis has been useful in understanding tumor growth. Recent research has shown that certain leukemic cells can be transformed into non-dividing mature cells by adding specific substances.
