1. A method of analyzing a biological sample of an organism, the biological sample including nucleic acid molecules originating from normal cells and potentially from cells associated with cancer, wherein at least some of the nucleic acid molecules are cell-free in the biological sample, the method comprising:

  • analyzing a plurality of DNA molecules from the biological sample, wherein analyzing a DNA molecule includes;

    determining a location of the DNA molecule in a genome of the organism;

    determining, by a computer system, whether the DNA molecule is methylated at one or more sites;

    for each of a plurality of sites;

    determining, by the computer system, a respective number of DNA molecules that are methylated at the site;

    calculating, by the computer system, a first methylation level based on the respective numbers of DNA molecules methylated at the plurality of sites;

    comparing the first methylation level to a first cutoff value; and

    determining a first classification of a level of cancer based on the comparison.
