Breast Tumours is the second volume in the 5th edition of the WHO series on the classification of human tumours. This series (also known as the WHO Blue Books) is regarded as the gold standard for the diagnosis of tumours and comprises a unique synthesis of histopathological diagnosis with digital and molecular pathology.

These authoritative and concise reference books provide indispensable international standards for anyone involved in the care of patients with cancer or in cancer research, underpinning individual patient treatment as well as research into all aspects of cancer causation, prevention, therapy, and education.

This book will be of special interest to pathologists, oncologists, surgeons and epidemiologists who manage or research breast tumours. Sections are included on all recognized neoplasms of the breast including the nipple and areola. Since the previous edition there have been changes based on recent molecular and genetic information, with impact on clinical practice.
