This book is devoted to the diagnosis and treatment of male breast pathology. It provides a comprehensive overview of current strategies for the diagnosis of breast malignancies in men, with a focus on imaging modalities. Ultrasound of male breast abnormalities is discussed in particular depth, but the roles of other imaging techniques, genetic tests, and interventional diagnostic modalities are also carefully covered. Special attention is paid to differential diagnosis of malignant and benign lesions, and the most important benign breast diseases are described and illustrated with high-quality images. A special chapter analyzes treatment strategy in men with breast malignancies and principles of follow-up after breast surgery. Individual chapters are also devoted to the diagnosis of recurrent cancer and cancer metastases. This up-to-date and richly illustrated book will interest and assist specialists in ultrasound diagnostics, radiologists, oncologists, and surgeons.
