The method of claim 10, wherein the obtaining step comprises measuring the biomarkers in the at least one biological sample. 12. The method of claim 10, further comprising displaying the calculated risk from (b) on a visual display. 13. The method of any one of claim 10, further comprising printing or storing the calculated risk on paper or an electronic storage medium. 14. The method of any one of claim 10, further comprising advising said individual or a health care practitioner of said risk evaluation. 15.
