Early Onset Breast Cancer: Epidemiology, Pathobiology, Diagnosis, Treatment, and Survivorship

This contributed volume addresses a critical gap in oncology by focusing on the distinct biological, clinical, and psychosocial aspects of early-onset breast cancer. As incidence among younger patients continues to rise, the book brings together pioneering research and clinical expertise to offer timely, evidence-based insights into tumor biology, genomic challenges, diagnostic complexities, emerging research directions, and tailored treatment strategies for this population. It serves as both a comprehensive reference and a practical guide for improving diagnosis, patient care, survivorship, and reducing diagnostic delays. The book seeks to answer a central question: How can we improve our understanding and treatment of breast cancer when it occurs at a younger age? Structured around key themes: epidemiology, molecular pathogenesis, risk factors, prevention, imaging, treatment, research priorities, and survivorship, it offers a detailed yet accessible resource for clinicians, researchers, and healthcare professionals. Topics such as fertility preservation, age-adapted therapies, and long-term quality of life highlight its relevance to real-world care and decision-making. The volume comprises 27 chapters by leading global investigators and contributors to the field, with a Foreword by Dr. Larry Norton of Memorial Sloan Kettering Cancer Center in New York, USA. Offering a holistic perspective on the cancer journey of young women, this book is essential for clinicians, oncologists, surgeons, radiologists, genetic counsellors, public health professionals, researchers, trainees, students, and patient advocates. It sheds light on disparities, quality-of-life issues, and the urgent need for age-specific treatment protocols.
