This chapter argues that effective medicine must combine the biomedical model with psychosocial care. The biomedical approach focuses on measurable data, but can overlook the patient’s subjective experience. The biopsychosocial model, proposed by George Engel, integrates biological, psychological, and social factors, recognising their bidirectional influence on health. For cancer care, this means treatment should address more than just malignant cells; it must also focus on the patient’s quality of life, personal meaning, and self-management. The chapter advocates for using arts and illness narratives to understand the patient’s perspective, asserting that collaboration and humanity are essential to healing.
