For-tunately, these glands are not frequently involved, a circumstance whichmay be accounted for by the atrophy of this channel in senUe mammas,in which cancer usually develops (Poirier) (Primrose, Ibid.). Retraction ofthe nipple is present in over one-hal,f of the cases. It occurs when the growthis near the nipple, and is due to the contracting fibrous tissues of the tumorpulUng on the milk-ducts. If the growth is far away from the nipple,. Fig. 1002.—Carcinoma of right breast. Lesion first noticed sLx months before photograph was made. a dimple is apt to form on the skin of the breast because of the pulling uponthe suspensory fibers. Neither retraction of the nipple nor a cutaneous dimpleproves the existence of cancer. One or both may be noted in a breast con-taining a scar (from a wound or a healed abscess), in tuberculosis of the breast,and in mammary syphilis. The dimple is not due to adhesion between thetumor and the skin. It is noted even when the tumor is far away from the may not be obvious unless the gland is moved to and fro or unless the skinover the breast is pushed in various directions. When this is done it becomesevident that the skin, at a certain point, is held inward. The dimple is avery valuable early symptom. Glandular enlargement in the axilla soon follows the appearance of ascirrhus; the glands become very hard and adherent. In over 60 per cent,of pe
