Table 3. Benignity and malignancy classification performance metrics.

Dataset	Class	ACC	PRC	REC	F1
Test A	benign	0.983	1.000	0.970	0.976
	malignant	–	0.964	1.000	0.982
Test B	benign	0.950	0.800	1.000	0.889
	malignant	–	1.000	0.938	0.968

Notes.

Classification performance is very high for both benign and malignant in both datasets. The relatively low precision (PRC) of 0.800 for benign cases in test set B may be attributed to one FP detection with respect to the low total number of four benign samples. Classification accuracy (ACC) is evaluated jointly for benign and malignant cases.
