Diaphanography test data set

Description

Diaphanography test is a noninvasive method (diagnostic test) of breast examination by transillumination using visible or infrared light to detect the presence of breast cancer. The test was performed on 900 patients. Only 88 patients were verified by breast tissue biopsy for histological examination (gold standard test). The percentage of unverified patients is 90.2%.
