Breast Cancer Wisconsin (Diagnostic) data set 1: Description. This database contains features computed from a digitized image of a fine needle aspirate (FNA) of a breast mass. They describe characteristics of the cell nuclei present in the image. The task is to determine if a found tumor is benign or malignant. 2: Type. Classification 3: Origin. Real world 4: Instances. 569 5: Features. 30 6: Classes. 2 7: Missing values.
