Abstract

Early and correct diagnosis plays a key role in enhancing the outcome in brain tumor and lung cancer patients.

Traditional Artificial Intelligence (AI) and Deep Learning (DL) models are handicapped by expensive computational costs and

challenges in handling high-dimensional medical data. This research article presents a Quantum AI based Diagnostics System

employing a hybrid quantum-classical computing model. The framework combines traditional feature preprocessing with the

exponential power of quantum computing. For classification in brain tumors (e.g., LGGs/HGGs), the quantum core uses a

Hybrid Quantum-Classical Integrated Neural Network (HQCINN) or Variational Quantum Classifier (VQC). For lung cancer

prediction, the framework might employ quantum-enhanced clustering such as Quantum-Enhanced K-Medoids or optimization

models such as Quantum --Genetic Binary Grey Wolf Optimizer (Q-GBGWO) with Extreme Learning Machines (ELM). This

hybrid methodology is intended to achieve superior diagnostic efficacy and speed across both MRI and CT modalities, laying the

groundwork for faster and more individualized clinical diagnostics.
