Malignant 40.2% (420/1000), benign 59.8% (598/1000), malignant over 40 years old 59.2% (297/502), metastatic cancer 58.2% (292/502), malignant under 40 years 21.2% 105/498), metastatic cancer 13.8% (69/498). A clear 377 cases of primary tumor, not found in 25 cases of primary tumor accounted for 6.2% (25/402).
