1940Endocrinology XXVII. 892 Only mammogen 1 (the duct growth factor) is present in ether-soluble extracts of the AP. Work is now progressing on the concentration of mammogen 2, the lobule-alveolar growth factor, and also on the perfection of a suitable technic for the assay of this hormone. 1958Proc. R. Soc. B. CXLIX. 306 Oestrogen may resume its role as a mammogen. 1971Cowie & Tindal Physiol. Lactation iii. 115 Although the concept of specific mammogens of pituitary origin was never widely accepted..the ‘Mammogen’ theory rightly centred attention on the role of the anterior pituitary in mammogenesis.
1958Proc. R. Soc. B. CXLIX. 312 The placenta may contribute as much to mammogenesis as the pituitary and ovaries combined. 1971Cowie & Tindal Physiol. Lactation iii. 117 Only in the rat and mouse have such detailed analyses of the hormones concerned in mammogenesis been made.
1938Proc. Soc. Exper. Biol. & Med. XXXVII. 608 This new pituitary principle will be called the ‘mammogenic hormone’. 1940Endocrinology XXVII. 888 (heading) Evidence for the presence of a second mammogenic (lobule-alveolar) factor in the anterior pituitary. 1958Proc. R. Soc. B. CXLIX. 304 Mammogenic activities of the ovarian hormones. 1971Cowie & Tindal Physiol. Lactation iii. 122 There is..a vast literature on the mammogenic potencies of ovarian steroids.
1937N. F. Hicken in Surg., Gynecol. & Obstetr. LXIV. 594/1 The procedure utilizes contrast fluids which are injected directly into the milk ducts, thus giving an accurate roentgenographic pattern of the ductal and secretory system of the mammary gland. The terms ‘mammography’ and ‘mammograms’ have been coined to describe these examinations. Ibid., Gentleness, persistence, and patience are requisite in obtaining good mammograms. Ibid. 594/2 These mammographic visualizations afford an excellent method of studying both the physiological and pathological changes of the breast. 1969New Scientist 13 Mar. 570/3 Preliminary designs for a commercial version of the system for producing mammograms.
1968N.Y. Times 25 Mar. 25 This image Dr. Wolfe and many other radiologists agree is far clearer and more detailed than film mammographs. 1970Daily Tel. 23 Oct. 17/4 The mammograph is another X-ray machine. Each breast is X-rayed individually, rather as though it were under a microscope.
1973M. J. Brennan in Holland & Frei Cancer Med. xxvii. 1776/2 Combined clinical and mammographic screening detected breast cancer at a rate of 2·72 per 1,000 initial examinations.
1969New Scientist 8 May 276/1 Thermography can detect presymptomatic breast cancers even when they are not palpable nor shown up by mammography. 1971Daily Colonist (Victoria, B.C.) 26 Nov. 2/2 If you are still worried, you could have a mammography done—an X-ray technique commonly used in women with breast lumps that have to be identified. |
