While cancer affects primarily the elderly, it also occurs in younger age groups, with different implications specifically relating to reproduction. Cancer can also occur during pregnancy itself. This brings together two diverse areas of medicine, encompassing the complexity of cancer and its varied biology and the equally challenging areas of fertility, conception and pregnancy. The 55th RCOG Study Group brought together a range of experts to examine these issues. This book presents the findings of the Study Group, with sections covering: epidemiology, genetics and basic principles of chemotherapy and radiotherapy fertility issues and paediatric cancers gynaecological cancers and precancer diagnostic dilemmas the placenta non-gynaecological cancers multidisciplinary care and service provision."
