Although breast tissue is in both sexes, it is more active and functional in women than in men. Breast tissue, which includes morphological and functional changes, including pre-puberty, reproductive and later periods, can be exposed to various diseases directly or indirectly related to all these changes. The human breast, especially in women, hosts a wide array of health conditions that range from simple to diagnose and treat, to diseases with high morbidity and mortality. Therefore, it also concerns multidisciplinary approaches that include different medical departments, not a single medical department. Considering all this, an updated approach to breast diseases will always be necessary. Within the scope of this book, an up to-date work will be created by treating breast tissue as anatomical, physiological and clinical by experts in the field.
