This paper presents a multi-disease prediction system that uses machine learning and deep learning algorithms to predict seven chronic diseases: diabetes, heart disease, kidney disease, liver disease, breast cancer, malaria, and pneumonia. The system aims to provide accurate predictions to help prevent the onset of these diseases, which are common and can significantly impact a patient's health and well-being. The authors use Flask to create a web application that integrates prediction models for these diseases. Deep learning models, particularly a CNN model, are employed for predicting diabetes, breast cancer, heart disease, kidney disease, and liver disease, while a CNN model is used for malaria and pneumonia. The system leverages historical patient data, such as blood pressure, blood sugar levels, age, and other relevant factors, to make precise predictions. The research emphasizes the importance of accuracy in disease prediction to avoid unnecessary anxiety and improve patient outcomes.This paper presents a multi-disease prediction system that uses machine learning and deep learning algorithms to predict seven chronic diseases: diabetes, heart disease, kidney disease, liver disease, breast cancer, malaria, and pneumonia.
