The present invention relates to a method for detecting breast cancer using a breast cancer specific biomarker. More specifically, CHL1 is a breast cancer specific expression reducing gene. Gene {NM_006614, cell adhesion molecule with homology to L1CAM (close homolog of L1)} Or TF The present invention relates to a breast cancer comprising a methylated CpG island of a promoter region of a gene (NM_001063, iron ion-binding transport protein, transferrin) or a biomarker for diagnosis thereof, and a breast cancer using the biomarker and a method for detecting the progression step. By using the biomarker of the present invention, early diagnosis of breast cancer can be performed more accurately and faster than conventional methods, and serum, which is a non-invasive sample, can be used as a sample, so that breast cancer can be diagnosed more simply and accurately. |
