The UCI Breast Cancer Dataset is obtained by numerically processing the UCI Breast Cancer binary classification modeling data, which includes calculating features from FNA digitized images of breast masses. The original data of UCI Breast Cancer is a breast cancer dataset, which contains three sets of breast cancer cell pathology feature images.

This dataset was released by the University of Wisconsin-Madison Diagnostic Center and Computer Science Institute in 1995. The main publishers were Dr. William H. Wolberg and General Surgery Dept. Related papers include "Breast cancer diagnosis and prognosis via linear programming" and so on.
