Breast carcinomas with false negative mammogram correspond to carcinomas diagnosed with means other than mammogram when the mammogram, at the time of diagnosis, showed no significant abnormality. The rate of false mammogram is difficult to ascertain because few studies have been published on this subject. The absence of mammographic abnormality is related to histopathological characteristics of the tumor and mammographic features of the patient's breast tissue. The small size of the tumor, the lack of microcalcifications often due to tumor necrosis and the absence of any significant associated desmoplastic reaction are the main histopathological factors encountered, particularly for dense breasts.
