In September 1989, another mammogram indicated residual breast cancer that the previous operation had missed. The earliest breast cancers, however, are detected by a mammogram. The follow-up mammogram and MRI examinations found neither defects (necrosis) nor abnormalities (neoplasms). Medical institutions may run advertisements for mammogram or other breast-related services. Scintimammography is not used for screening or in place of a mammogram. Cancer, cardiology, mammogram, hospice and children's services are some of the specialty centers. They would then be called back for a "diagnostic mammogram".
