The authors investigate the differences between the angiogenesis that occurs in malignant and benign breast tumours (10 specimens of invasive ductal carcinoma and 10 specimens of fibroadenoma) as well as in the adjacent breast stroma of these women highlighting the microvessels by staining their endothelial cells for factor VIII immunohistochemically. The(More)
