[A method of submacroscopic study of the whole human breast (author's transl)].

A method of submacroscopic study of the whole human breast is described. Breasts are removed surgically or at autopsy. Serial thin sections (2mm.) are defatted, stained, clarified, preserved in sealed plastic bags, observed under a dissecting microscope and photographed. The lesions found are interpreted and removed for histological examination. The method is simple, allows a careful and complete study of the glandular lesions and appears to be suitable for studies on origin and development of human breast cancer.
