Abstract

Introduction: Breast cancer (BC) is a malignant neoplasm that has a considerable impact on women's lives and is one of the main causes of mortality among women. Its prevalence and severity highlight the importance of ongoing research to deepen our understanding of this disease. Objective: To explore the role of immunohistochemistry as an essential tool in the diagnosis and prognostic evaluation of CM. Methods: This is a literature review using scientific articles from the US National Library of Medicine (PubMed) and Scientific Electronic Library Online (SciELO) databases. To identify the relevant studies, descriptors from DeCS (Health Sciences Descriptors) were used with the Boolean operator “AND”, including the terms “Breast cancer”, “Immunohistochemistry” and “HER2+ protein”. Free full texts, published in peer-reviewed journals, available in English and Portuguese, and studies published between 2019 and 2023. Studies that were not directly related to the proposed topic were excluded from the analysis. Results: Immunohistochemistry demonstrates efficacy in accurately detecting the HER2+ protein in breast cancer, and is essential for assessing prognostic factors and differentiating lesions in breast tissue. Its ability to reliably identify the protein and discriminate between different types of BC contributes to a more precise and personalized therapeutic approach, improving patients' clinical outcomes. Conclusion: Immunohistochemistry is crucial in the diagnosis and understanding of breast cancer. In addition to confirming the diagnosis, it identifies the presence of HER2+ and other markers, influencing therapeutic and prognostic decisions. This personalized approach promotes more effective treatment, highlighting the importance of immunohistochemistry in the management of BC.
