Worldwide, breast cancer is by far the most common cancer amongst women, with an incidence rate more than twice that of colorectal cancer and cervical cancer and about three times that of lung cancer. Whilst screening programmes have improved detection, this disease still places a very high burden on healthcare services worldwide. Over the last two decades, improved public awareness, the implementation of population screening by mammography, and the development of new technology for diagnosis have transformed the care of patients with breast cancer. In this volume, recognised experts discuss key current issues in the diagnosis and management of breast disease. The development and application of new diagnostic techniques is described as well as the use of sophisticated drugs for more effective treatment. Complex contentious topics including risk factors, borderline lesions, professional performance and quality assurance are thoroughly explored by an expert multidisciplinary team.
