Cancer examination reagent set, production method for cancer examination reagent set, and cancer examination method

A production method for a cancer examination reagent set including a primary examination reagent and a secondary examination reagent, the production method for a cancer examination reagent set, comprising the following (a) to (e):

• (a) creating a CpG site set P consisting of CpG sites having a significant difference in degree of methylation in at least one kind among n kinds of cancers, where n is a natural number of 3 or more;
• (b) selecting a part of the CpG sites constituting the CpG site set P to create a CpG site set 1;
• (c) selecting a part of the CpG sites constituting the CpG site set P to create each of nC2 kinds of CpG site sets 2 for discriminating two kinds among the n kinds of cancers;
• (d) producing a reagent for analyzing a degree of methylation of the CpG site set 1 to form the primary examination reagent;
• and
• (e) producing nC2 kinds of reagents for analyzing degrees of methylation of the nC2 kinds of CpG site sets 2, respectively, to form the secondary examination reagent.
