title: High risk breast tumor patients.
abstract: A unique scheme for placing the most breast carcinoma patients into the least population includes newly developed systems to analyse 64 clinical and radiographic risk factors in combinations. The calibration sample consisted of 540 cancerous and 641 non-cancerous breasts. In an independent validation sample of 73 carcinoma and 462 non-carcinoma breasts, 90 percent of the potential malignant breasts were correctly classified with only 12 percent of the non-malignant breasts misclassified. Thus, the scope of prediction and delineation of malignant and non-malignant and non-malignant groups is extended.
