A Machine Learning Approach for Disease Prediction Based on Age, Lifestyle Habits, and Symptom Analysis

Abstract: This project is about making a smart web system that helps people know if they are at risk of getting five common diseases. These diseases are heart disease, cancer, liver disease, diabetes, and chronic bronchitis. The system uses artificial intelligence (AI) to look at personal health information like age, smoking and drinking habits, sleep routine, how much exercise a person does, and what symptoms they have. Before training the models, the data was cleaned and changed using encoding and scaling so the AI could understand it better. Two machine learning models, Random Forest and Support Vector Machine (SVM), were trained to predict the risk of these diseases. The Random Forest model gave a very high accuracy of 96.8%, while SVM gave 95.3%. These models were added into a Flask-based web app, and MongoDB was used to save real-time user data and predictions. This system helps people take care of their health early. In the future, more diseases will be added, and it will be tested with real users.
