Mammographic Negative Cancer Detected by Ultrasound

Abstract

A few quotations from the book Breast Cancer: A Lobar Disease by Tibor Tot will be used as an introduction to this chapter, which will be followed by the presentation of several cases of early breast cancers invisible on mammography and detected by ultrasound. It is exactly through the presentation of the cases mentioned above that I will prove the theory stated in the quotations claiming that breast cancer is a lobar disease, even at the earliest stages. Lesions, detected by ultrasound, were cytologically verified under ultrasound control, and then an open biopsy was performed after a preoperative marcation under ultrasound control. All the lesions were impalpable, invisible on mammography, and up to 10 mm long at the ultrasound examination.

Pathohistological analysis would confirm malignity of lesions detected by ultrasound but also the existence of additional malignant microscopic lesions around the primary process, which required reoperation—quadrantectomia. Additional pathohistological detecting of microscopic foci in situ or microinvasive carcinoma in the tissue obtained by quadrantectomia (multifocality or diffusivity) would indicate subcutaneous mastectomy with primary reconstruction.
