Leveraging NLP for Medical Text Analysis and Diagnosis Support

Abstract The integration of Natural Language Processing (NLP) into the healthcare domain has revolutionized the way medical information is processed, analyzed, and utilized. With the exponential growth of unstructured data in Electronic Health Records (EHRs), clinical notes, radiology reports, and biomedical literature, NLP provides an effective mechanism to extract, structure, and interpret valuable insights from vast textual datasets. This paper explores the significant role of NLP in medical text analysis and diagnosis support, focusing on its methodologies, applications, and implications for clinical practice. NLP techniques such as Named Entity Recognition (NER), text classification, relation extraction, and semantic analysis enable the identification of key clinical concepts including diseases, medications, symptoms, and treatment patterns. These tools assist in automating administrative tasks, supporting physicians in clinical decision-making, and improving diagnostic accuracy. Furthermore, deep learning models such as BioBERT, ClinicalBERT, and MedRoBERTa have significantly advanced medical NLP applications by providing contextual understanding of domain-specific terminology. The difficulties in implementing NLP in the healthcare industry, such as data protection, interoperability, and model interpretability, are also covered in the study. It illustrates how NLP-based systems might improve patient outcomes, streamline healthcare delivery, and support precision medicine through an analysis of recent research. Highlighting how NLP technology may improve diagnosis assistance, decision-making, and patient-centered care in the contemporary healthcare environment by bridging the gap between unstructured medical data and actionable clinical intelligence is the ultimate goal.
