Abstract: A method for generating a model for epithelial ovarian cancer is presented, comprising the steps of obtaining a mass spectrum for each of a plurality of samples, segmenting each of the mass spectra into “bins,” and determining a plurality of relationships between two or more bins. One are more statistically significant factors are identified according to the determined plurality of relationships, and a predictive model is generated as a function of the one or more identified factors. A method of the present invention may further comprise the step of obtaining one or more nuclear magnetic resonance spectra of each of the samples, which are segmented into a plurality of bins. Combinations of mass spectra and NMR spectra may be used to determine the plurality of relationships. In other embodiments, methods for identifying the presence of EOC indicated by a biological sample of an individual are presented.
