Patrick Forrest, Regis Professor of Clinical Surgery at the University of Edinburgh talks about breast cancer. A brief summary accompanying the cassette reads: "The first demonstration that the endocrine system can influence human breast cancer was in 1896, when Beatson described remission of advanced local disease following oophorectomy. Since then, work both in experimental animals and in man has failed to define precisely the reason for this effect. This programme, which reviews these various studies, includes information on the effect of hormones on the induction and growth of experimental tumours; on correlations between curculating hormones and the behaviour of human cancer; and on the ways in which the tumour itself can facilitate hormonal action." 5 segments.
