FIRST PRIZE Winner in the Oncology category of the 2010 BMA Medical Book Competition. Intensive research over the last fifteen years has yielded a vast expansion in our understanding of the role of inheritance and genetics in a variety of cancers. Several inherited conditions have been identified which result in a high risk of various cancers; some of these were previously recognized, but the genetic basis underlying them has now been elucidated. This knowledge is now entering the sphere of routine clinical care. Surgeons, gastroenterologists, gynaecologists, oncologists, endocrinologists and many others need an awareness of these disorders, an understanding of genetic testing and when it is indicated, and how to manage patients with inherited cancer predisposition and their families. This book covers the basic concepts of cancer genetics. The common inherited cancer syndromes are each dealt with in greater depth, with the current management outlined. This book is aimed at all clinicians who may encounter these conditions in their practice. It aims to facilitate identification of high-risk individuals and families, to inform interaction with geneticists and other subspecialists, to provide a basis for patient management and to stimulate interest in these fascinating conditions.
