This inaugural Handbook of Oncology Social Work: Psychosocial Care for People with Cancer, provides, for the first time, a repository of the breadth and scope, art and science, of oncology social workers' practice, education, research, policy and program leadership in the psychosocial care of people with cancer and their families. Persons with cancers are confronted with a deluge of information and decisions about their illnesses and the impact on their lives. Oncology social workers play a crucial role in helping patients and caregivers navigate this sea of choices. The Handbook of Oncology Social Work encompasses the breadth and depth of expertise and compassion that oncology social workers bring to individuals and families living with cancers.
