Abstract: Breast cancer is a malignant tumor that seriously threatens the physical and mental health of women. In China， the incidence of breast cancer is the first of the female malignant tumors in big cities， and the incidence of the disease is increasing year by year. Many imaging methods are currently used for early screening of breast， such as clinical breast palpation （CBP）， mammography （mammography）， ultrasound imaging （ultrasonography， US）， computed tomography （CT）， magnetic resonance imaging （magnetic resonance imaging， MRI）， and positron emission. Tomographic imaging （PET）， and breast thermal tomography，especially the application of breast biopsy are aimed at improving the detection rate of early breast cancer.

Key words: imaging methods, early breast cancer
