The book offers an introduction to the author's work in her internship supervision practices in Psycho-Oncology. It highlights a field of training in Health Psychology that links Therapeutic Support, Oncology and Psychology, specifically Cognitive Behavioural Therapy.

She goes through some important concepts for the training of undergraduate students in the health field, pointing out the main problems of patients facing cancer at different stages of development: children, adults and the elderly. It doesn't neglect the everyday problems of contemporary society, such as gender issues and other political aspects of social inclusion.
