The integration of AI in cancer diagnostics allows for improved accuracy, speed, and efficiency in identifying malignancies at early stages, thus significantly impacting patient outcomes. However, the effectiveness of AI in cancer diagnosis is contingent upon the quality and availability of data, which presents several challenges and limitations.

AI assists in cancer diagnosis primarily through its capabilities in processing and analyzing large volumes of multi-omics data derived from various sources, such as genomic sequencing, imaging, and clinical records. Techniques such as deep learning and computer-aided diagnosis have demonstrated considerable potential in enhancing diagnostic accuracy, particularly in high-incidence cancers like breast and lung cancer (Vyas et al. 2025; Wang et al. 2024). These technologies can identify patterns and anomalies in imaging data that may be overlooked by human clinicians, thereby facilitating early detection and timely intervention.

Despite these advancements, the challenges related to data quality and availability are significant. A primary limitation is the scarcity of comprehensive datasets, particularly for rare cancers. The lack of sufficient training data hinders the development and validation of robust AI models, leading to potential biases and inaccuracies in diagnosis (Huhulea et al. 2025; Tiwari et al. 2025). Furthermore, existing datasets may contain inconsistencies or incomplete information, which can adversely affect the performance of AI algorithms.

Additionally, the integration of AI into clinical practice is often impeded by the variability in data standards and formats across different institutions. This lack of standardization complicates the aggregation of data necessary for training AI systems, ultimately affecting the generalizability of AI models in diverse clinical settings (Alshuhri et al. 2024; Pereira Cabral et al. 2023).

Moreover, ethical concerns regarding data privacy and security pose significant barriers to the utilization of AI in cancer diagnostics. Ensuring patient confidentiality while leveraging extensive datasets for AI training is a critical challenge that must be addressed to foster trust and acceptance among healthcare providers and patients alike (Kolla & Parikh 2024; Wang et al. 2025).

In conclusion, while AI holds transformative potential for improving cancer diagnosis through enhanced data analysis and pattern recognition, its efficacy is closely linked to the quality and availability of data. Overcoming the challenges related to data scarcity, standardization, and ethical considerations is essential for the successful integration of AI technologies into clinical oncology, ultimately leading to better patient care and outcomes.

5.2 Interpretability of AI Models ​

In summary, AI is poised to significantly enhance cancer diagnosis through improved accuracy and personalized treatment strategies. Nevertheless, overcoming existing challenges and addressing ethical considerations will be essential for the successful integration of AI into routine clinical practice. The future of AI in oncology holds the potential to reshape cancer management, ultimately leading to improved patient outcomes and more effective healthcare delivery.

7 Conclusion ​

The integration of artificial intelligence (AI) in cancer diagnosis represents a significant advancement in oncology, promising to enhance diagnostic accuracy, efficiency, and personalization of treatment strategies. The application of machine learning, deep learning, and data analytics has transformed how clinicians detect and manage cancer, particularly through improved imaging techniques and genomic data analysis. Successful implementations in clinical settings demonstrate AI's potential to streamline workflows and provide critical insights for patient management. However, challenges remain, including data quality, model interpretability, and regulatory compliance, which must be addressed to facilitate widespread adoption. Future research should focus on developing explainable AI models, enhancing data integration methods, and establishing robust ethical frameworks to ensure the responsible use of AI in healthcare. As these technologies continue to evolve, they hold the promise of reshaping cancer diagnosis and management, ultimately leading to better patient outcomes and a more efficient healthcare system.
