Cancer affects the breast more frequently than any other organof the body. All the varieties of carcinoma have been met withhere; scirrhus is, however, by far the most frequent form in whichit occurs primarily. The encephaloid variety may be primary, butis more commonly engrafted upon the former; the colloid formis the most rare. When associated with other cancers, that of themamma is stated by Dr. AValshe to be invariably primary, exceptin those rare instances when the disease spreads from the lymphaticglands or superjacent skin. 3 £ •S6 CAXCER OF THE :MAMMA. Fio. g out branchesand %, •0/ Scirrhus occurs in the form of a hard, lobulated tumour, im-bedded in the adipose tissue of the gland, causing adhesion to theskin, and retraction of the nipple ; it is at first somewhat movable,but soon becomes firmly adherent to the subjacent parts, in-volving more or less of the gland tissue, the thoracic muscles, andthe adjoining lymphatic glands. Instead, however, of occurring asan isolated tumour in the first instance, it may from the com-mencement appear as an infiltration of the various structures of the part; it will in that case beill-defined, sendininto the adjacent tissues,involving in its mass the lactealtubes and lymphatics. These be-come contracted and flattened intobands, which give a peculiar ap-pearance to this form of mammarycancer.
