All patients who are part of TCIA at this time are cancer-positive by definition. We have no collections of non-malignant tumors or healthy patients. The only exception would be patients with multiple tumors who might have a benign tumor in addition to a malignant tumor, but at least one tumor will be malignant in each patient.
