Esophageal Cancer Detection
A final-year project exploring how quantum mechanics principles can strengthen medical image classification.
01 — Overview
What this project is
Esophageal Cancer Detection was my final year project — a system that explores how quantum mechanics principles can be applied to medical detection, specifically the early classification of esophageal cancer from diagnostic data.
The motivation is real. Esophageal cancer is one of the harder cancers to catch early, and even small improvements in detection accuracy translate directly into better patient outcomes. Traditional machine learning has been applied to this problem extensively. The question I wanted to explore was whether quantum-inspired techniques — leveraging properties like superposition and entanglement-style feature interactions — could meaningfully improve on classical methods.
The result is a working detection pipeline that combines quantum mechanics-based feature analysis with traditional ML classification. It's not a production medical device — it's a research-grade prototype demonstrating that the hybrid approach is viable, and worth further exploration.
02 — Key Features
What it does
- End-to-end detection pipeline — from raw diagnostic data to classification output
- Quantum-based feature analysis applying quantum mechanics principles to medical signal processing
- Hybrid classical-quantum architecture combining the strengths of both paradigms
- Full ML pipeline integration with preprocessing, model training, and accuracy benchmarking
- Production-level data science practices — proper train/test splits, cross-validation, evaluation metrics
03 — Tech Decisions
Why these tools
Quantum mechanics principles for feature analysis
The core hypothesis was that quantum-inspired techniques could capture relationships between features that classical methods miss. Superposition-style representations let multiple feature interpretations exist simultaneously during analysis, and entanglement-style feature interactions can model dependencies that linear methods underweight. This wasn't quantum hardware — it was the mathematical framework applied in software.
Python as the host language
Python's the natural choice for both the quantum side and the ML side. Quantum computing libraries like Qiskit and PennyLane have first-class Python APIs, and the entire scientific computing ecosystem (NumPy, Pandas, scikit-learn) is Python-native. Keeping the whole pipeline in one language meant no friction at the boundary between quantum and classical components.
Hybrid over pure-quantum
A pure quantum classification system isn't practical with current hardware constraints. The hybrid approach — quantum-inspired feature analysis feeding into classical ML — gets you the conceptual benefits of quantum techniques without requiring access to a real quantum computer. It's also more honest about what's actually doing the work at each stage.
Pandas + NumPy for the data layer
Medical data has structure — patient records, diagnostic features, classification labels. Pandas DataFrames made it easy to inspect transformations as I went, and NumPy was the bridge to the quantum-inspired math.
