The purpose of this paper is to present an oncology case study focusing on a woman's journey through breast cancer treatment and survivorship and a nurse's journey to provide wholistic care using standardized nursing languages and Rogers's Science of Unitary Human Beings (SUHB). Published literature, experience, and expertise of the author were used as data sources. The data were clustered to formulate oncology nursing care based on the standardized nursing languages of NANDA International, Nursing Outcomes Classification, and Nursing Interventions Classification (NNN) from the theoretical foundation of Rogers's SUHB. The use of Rogers's SUHB, NNN, and the extant literature provided a theoretical, evidence-based, and practical approach to providing holistic care for a woman journeying through breast cancer treatment and survivorship. Nurses can use standardized nursing languages and Rogers's SUHB to facilitate personal well-being and quality of life for breast cancer survivors.
