With increasingly developed technology, a detection system for skin cancer can be made with image segmentation using fractal methods and KNearest Neighbor classification. Image data will be processed using the fractal method to find the unique characteristics of each image data. Then the K-NN classification will calculate the closest distance between the test data and the training data, the K-NN work process starts from determining the k parameter (the number of closest neighbors) then calculating the square of the distance of each object to the sample data. The classification will be divided into three classes, namely: melanoma skin cancer, nevus skin cancer, and seborrheic keratosis skin cancer. In this study, the highest accuracy was 90.7% with a computation time of 93.2 seconds by using a 512 x 512 image resize and the value of K = 1 with training image data of 300 and test image of 150, the value of K = 1 is the most optimal K value among K-NN Classification.
