Breast reconstruction using myocutaneous flaps has been widely used in patients undergoing modified radical mastectomy for the treatment of breast cancer with significant improvement in esthetical results, which also helps to improve self-esteem of the patients as it minimizes the feeling of mutilation, without changing disease prognosis. Previously, it was believed that there was no risk of recurrence in the reconstructed breast due to the complete removal of breast tissue. However, histological studies have shown that a small amount of glandular tissue may remain after mastectomy, with a high potential for malignancy. Clinical follow-up of mastectomy patients is recommended as most recurring lesions occur at the flap margins and can be detected by palpation. In addition, the inclusion of mammographic and ultrasound monitoring has been proposed for the follow-up of patients as these methods may contribute to the diagnosis of recurrent lesions before they become palpable.

In digital mammography, imaging acquisition, display and storage processes are separated and individually optimized. Radiation transmitted through the breast is absorbed by an electronic detector with an accurate response over a wide range of intensities. Once these data are stored, they can be displayed by means of computer image-processing techniques to allow arbitrary settings of image brightness, contrast and magnification, without the need for further radiological exposure of the patient. In this article, the current state of the art in technology for digital mammography and clinical trials data supporting the use of this technology are reviewed. In addition, several potentially useful applications, currently under development with digital mammography, are described.

The distribution of fibroglandular tissue in the breast is often symmetrical. Changes in that symmetry may indicate a hidden lesion in the parenchyma. The evaluation of asymmetric densities in the breast is one of the main day-to-day challenges for radiologists, i.e., differentiating normal superimposed structures from true parenchymal lesions. The knowledge of different techniques and resources used to investigate asymmetric densities as well as evaluation protocols are essential to establish the nature of the lesions. Asymmetric densities may be the only sign of breast cancer otherwise clinically and radiologically concealed.
