Breast cancer is a major cause of death in women, but AI can help diagnose it early and accurately. Scientists reviewed studies on using machine learning to classify breast tumors. They found that algorithms like SVM, K-NN, and RF can distinguish between malignant and benign tumors in medical images. SVM had high accuracy of about 97%, and adding functions like bagging and boosting improved its effectiveness. Deep learning with CNN achieved even higher accuracy, over 98%.
