Abstract
Angiography of the breast was studied in 93 cases of cancer, 34 of mastopathy and seven of fibroadenoma
1) The most important feeding arteries in breast cancer are the internal mammary, lateral thoracic and superficial thoracic.
2) In breast cancer compared with benign tumor there were seven abnormal findings : chaotic arrangement, straight course, irregular tortuosity, dilated vessels, hypervascularity, lymph node stain and tumor stain (p<0.05).
3) The diagnostic rate of breast cancer by angiography was 86.0%. With tumor whose maximum diameters were less than 2.0cm, it was 73.1%. The diagnostic rate of these small tumors was significantly higher with angiography than when other methods were used. In medullary tubular carcinoma, angiographic diagnosis was most effective, with a diagnostic rate of 95.8%.
4) In the high-density tumor stain, vessels of less than 200 micron caliber were increased and dilated, and fibrostomal reaction and density of the cancer nest were high.
It was suspected that the density of tumor stain was related to hematogeneous metastasis and has some effect on chemotherapy.
5) Lymph node stain of carcinoma seemed not to be related to metastatic lymph node.
