This book, written by global experts in the field, provides a thorough overview on fertility and pregnancy challenges and solutions in women who are being or have been treated for cancer. The book addresses several topics, including pregnancy outcomes after a cancer diagnosis, the impacts of systemic anticancer therapy on fertility, the essentials of fertility preservation approaches in cancer patients, and fertility counseling. This is in addition to controversial topics like the role of ovarian stimulation in breast cancer patients, fertility preservation in cancer patients with BRCA mutation and the evolving role of GnRH analogues. Within this context, key open questions are discussed with reference to the latest evidence. The aim is to provide clinicians with a reliable resource that documents the most up-to-date knowledge on the feasibility and safety of the different approaches to fertility preservation and on the management of female cancer patients who would like to preserve fertility and achieve a pregnancy following their treatment.
