A vast majority of clinical information, rich with patient-specific details and nuanced observations, resides in unstructured formats such as physician's notes, pathology reports, and medical literature. This wealth of data often remains underutilized due to the challenges of manual extraction and analysis. Natural Language Processing (NLP), a specialized field of Artificial Intelligence, offers powerful techniques to unlock this untapped potential by enabling computers to understand, interpret, and process human language. This work explores the pivotal role of NLP in transforming unstructured healthcare data into actionable clinical insights. It details key NLP tasks-including Named Entity Recognition, Relation Extraction, Text Summarization, and Question Answering-and the underlying technologies, from traditional machine learning to advanced deep learning models like Transformers. The paper examines diverse applications, such as enhancing diagnostic accuracy, personalizing treatment strategies by extracting social determinants of health and patient preferences, advancing medical research through cohort identification and pharmacovigilance, and optimizing healthcare operations via automated coding and quality reporting. Furthermore, it addresses significant challenges, including the variability of clinical text, data privacy concerns (HIPAA/GDPR), the need for large annotated datasets, algorithmic bias, and the imperative for explainable AI. Ethical considerations, particularly regarding bias mitigation and ensuring patient confidentiality, are highlighted. Finally, the paper looks toward future directions, including the impact of Large Language Models (LLMs), multimodal NLP, and

The integration of Artificial Intelligence (AI) into healthcare is rapidly transforming diagnostic, predictive, and treatment planning paradigms, offering significant potential to enhance medical decision-making. However, this technological advancement introduces complex challenges to the foundational principles of informed consent, which are crucial for upholding patient autonomy and ethical medical practice. This work examines the critical need to re-evaluate and reimagine informed consent processes in the context of AI-supported healthcare decisions. It specifically addresses the difficulties in ensuring adequate patient education about complex AI systems-including issues of transparency, the "black box" phenomenon, and algorithmic bias-and the requirements for ethical disclosure. Key considerations include how to effectively communicate the role of AI, its performance characteristics, data governance, potential risks, benefits, and alternatives to patients with varying levels of health and digital literacy. The paper explores strategies for enhanced patient education, the evolving role of healthcare providers as interpreters of AI-driven insights, and the necessity for updated ethical frameworks and regulatory considerations. Ultimately, it argues for a proactive and adaptive approach to informed consent to ensure that as AI becomes more integral to healthcare, patient understanding, trust, and the ability to make genuinely informed choices are not only preserved but strengthened.
