Summary

Widespread use of mammography results in detection of small cancers with favorable prognosis, as well as an array of indeterminate lesions, the majority of which turn out to be histologically benign. This book gives a detailed account of the radiology and pathology of screening-detected lesions, with discussion of risk assessment, to assist clinicians in the follow-up of their patients. Related lesions are dealt with in consecutive chapters, giving the reader an opportunity for comparison. The book is well illustrated with radiological and pathological correlation of mostly screening-detected images including mucocele-like lesions and columnar lesions. All professionals who care for patients with breast disease, such as breast surgeons, radiologists, pathologists and breast care nurses, will find the book highly useful for the management of patients with benign or indeterminate breast lesions in a multidisciplinary setting.
