Author: Dr. William H. Wolberg, University of Wisconsin Source: [UCI](https://archive.ics.uci.edu/ml/datasets/breast+cancer+wisconsin+(original)), [University of Wisconsin](http://pages.cs.wisc.edu/~olvi/uwmp/cancer.html) - 1995 Please cite: See below, plus [UCI](https://archive.ics.uci.edu/ml/citation_policy.html) Breast Cancer Wisconsin (Original) Data Set. Features are 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 target feature records the prognosis (malignant or benign). [Original data available here](ftp://ftp.cs.wisc.edu/math-prog/cpo-dataset/machine-learn/cancer/) Current dataset was adapted to ARFF format from the UCI version. Sample code ID's were removed. ! Note that there is also a related Breast Cancer Wisconsin (Diagnosis) Data Set with a different set of features, better known as [wdbc](https://www.openml.org/d/1510). ### Relevant Papers W.N.
