The Concept: Clinical presentation, sonography, and mammography are the three pillars upon which the concept of this atlas is based. The strengths and weaknesses of these three pillars are fully explored, and it is shown how all three can be optimally integrated and supplemented to yield a confident and efficient diagnosis. Coverage includes digital mammography, positron emission tomography, and sentinel node biopsy. More than 1700 illustrations with clinical photographs, ultrasound images, and mammograms document our approach to establishing an accurate diagnosis for the various forms of breast cancer.
