This file contains material relating to meetings on 'The Endocrinology of breast cancer', 1957. Meetings between Stockholm and Edinburgh groups to review work in progress, were planned for 29 April 1957-3 May 1957, in Edinburgh. In the event, the Stockholm visitors were unable to attend, and the full programme was cancelled, and replaced by a one-day discussion meeting on 29 April 1957. The material includes the programme planned for the full meeting; Dott's notes made of his and others' contributions at the shortened meeting; and a duplicated copy of 'Provisional conclusions', March 1957-April 1957.
