Based on the results of Globocan Observatory 2020 data, breast cancer cases in Indonesia ranked first, with total new cases in 2018 amounting to 58,256 (16.7%) cases, in female patients infected with breast cancer amounting to 58,256 (30.9%) cases while for breast cancer death cases became second with a total of 22,692 (11.0%). Using the K- Nearest Neighbor (KNN) method which aims to classify mammogram images, the feature extraction used is the Gray Level Co-Occurrence Matrix (GLCM). The implementation is carried out as a learning on the K- Nearest Neighbor (KNN) and Gray Level Co-Occurrence Matrix (GLCM) methods. From the research that has been carried out, 20 data will be used to be tested on the K?Nearest Neighbor classification to get test results on the mammogram image classification system that has been made using the Confusion Matrix with an accuracy of 80%.} }
