Detection of breast cancer using machine learning and explainable artificial intelligence
This study employed machine learning (ML) and explainable artificial intelligence (XAI) techniques to detect breast cancer. Using diagnostic characteristics of patients, multiple ML classifiers were utilized, with Random Forest achieving the highest F1-score of 84%. A stacked ensemble model also performed well at 83%. XAI techniques like SHAP, LIME, ELI5, Anchor, and QLattice were integrated to provide transparency and interpretability, revealing underlying factors for predictions. The research emphasizes the applicability of interpretable AI in healthcare to assist practitioners, reduce diagnostic errors, and improve clinical decision-making.

Data Preprocessing & Feature Selection
The study rigorously compared various machine learning classifiers, including XGBoost, LightGBM, CatBoost, AdaBoost, KNN, Decision Tree, Logistic Regression, and Random Forest. Random Forest emerged as the top performer with an F1-score of 84%, demonstrating its robustness for breast cancer detection. A stacked ensemble model was also developed, combining the strengths of multiple base models, achieving an F1-score of 83%. This ensemble approach enhances generalization and mitigates overfitting, providing a more reliable predictive system for critical medical applications. The careful selection and optimization of these models underscore a strong foundation for accurate diagnosis. This directly translates to more reliable tools for medical practitioners, reducing uncertainty and improving the initial diagnostic phase for patients.
A core innovation of this research is the deep integration of Explainable Artificial Intelligence (XAI) techniques, including SHAP, LIME, ELI5, Anchor, and QLattice. These tools provide unparalleled transparency into the 'black box' of machine learning models. By elucidating the specific features and their individual contributions to a prediction, XAI enhances trust and interpretability. For instance, SHAP values revealed that 'involved nodes', 'tumor size', and 'age' are highly influential in breast cancer diagnosis. This transparency is crucial for regulatory compliance and for empowering clinicians to understand and validate AI recommendations, making the system more trustworthy and actionable in real-world scenarios. This ensures that AI systems are not only accurate but also accountable and understandable to all stakeholders.
The effectiveness of the models hinges on meticulous data preprocessing and feature selection. The 'UCTH Breast Cancer Dataset' was used, comprising 213 patient observations. Techniques such as handling null values, label encoding for categorical data, and Max-Abs scaling for numerical data were applied. Mutual information and Pearson's correlation were employed to identify critical features. Significant features included 'involved nodes', 'tumor size', 'metastasis', 'age', 'menopause', 'breast quadrant', and 'history'. This rigorous data preparation ensures that the models are trained on high-quality, relevant data, minimizing bias and maximizing predictive power. For enterprises, this means that the AI solutions are built on a solid data foundation, leading to more accurate and reliable outcomes, and reducing the risk of flawed insights from poor data quality.

Your AI Implementation Roadmap
A strategic overview of key phases for successful integration.
Phase 1: Data Integration & Baseline Model Development
Establish secure data pipelines from existing clinical systems. Clean, preprocess, and integrate patient diagnostic data. Develop initial ML models (e.g., Random Forest) to establish a performance baseline for breast cancer detection. This phase focuses on data readiness and foundational model accuracy.
Phase 2: XAI Integration & Model Refinement
Integrate SHAP, LIME, and other XAI techniques into the baseline models. Analyze feature contributions and model behaviors. Refine models based on XAI insights to improve interpretability and address potential biases. Conduct internal validation with domain experts (radiologists) to ensure clinical relevance.
Phase 3: Pilot Deployment & Clinical Validation
Deploy the interpretable AI system in a pilot program within a clinical setting. Collect feedback from medical practitioners on usability and diagnostic support. Conduct rigorous clinical validation to measure the impact on diagnostic accuracy, efficiency, and patient outcomes. Iteratively adjust the system based on real-world performance.
Phase 4: Scaled Rollout & Continuous Improvement
Scale the AI system across multiple diagnostic centers or hospital networks. Establish continuous monitoring for model performance, data drift, and XAI consistency. Implement a feedback loop for ongoing model updates and retraining with new data to maintain high accuracy and interpretability, ensuring long-term value.
