The invention relates to an optimal selection method of gene chip probes for cancer screening. The method is characterized in that the gene chip probes capable of being used for cancer screening are obtained through three stages of constructing a point mutation site (SNV) group, constructing a candidate probe group and verifying and confirming probes on the basis of nucleic acid data of a confirmed case of a selected cancer.
