The book highlights the importance and relevance of practicing bioethics in the age of personalized medicine. It presents concrete cases studies dealing with cancer and genetic diseases, where difficult decisions need to be made by all the parties involved:  patients, physicians and families. Decisions concern not only diagnostic procedures and treatments, but also moral values, religious beliefs and ways of seeing life and death, thus adding further layers of complexity to biomedical decision-making. This book, which is strongly rooted in the philosophical tradition, features non-directive counseling and patient-centeredness. It provides a concise yet comprehensive and practice-oriented guide to decision-making in modern healthcare.
