For the imaging presentation of breast cancer, which can be detected or suggested by mammogram, MRI or B-ultrasound with high suspicion of breast cancer, the images are mainly localized breast lumps with calcification, lobulation, and irregular morphology. For lumps that are highly suggestive of breast cancer, an ultrasound or CT-guided biopsy should be performed to further clarify whether the lump is breast cancer. The pathology of breast cancer is the only basis to confirm the diagnosis of breast cancer, and imaging can only suggest the diagnosis, but not determine it. Therefore, the imaging characteristics of breast cancer can only be treated objectively.
