Macmillan was a Baptist but also influenced by Quakerism. In founding the Society, Macmillan "wanted to see homes for cancer patients throughout the land, where attention will be provided freely or at low cost, as circumstances dictate... [and]... panels of voluntary nurses who can be detailed off to attend to necessitous patients in their own homes." Macmillan's Society was strictly
anti-vivisectionist. In the Society's first publication, Macmillan stated that the new organization "had no connection or any sympathy whatever with existing systems of cancer research, the representatives of which appear to be persuaded that "research" means "vivisection". In 1922, the Society's journal folded and there was only limited financial support. The Society failed to obtain new members and through deaths and resignations its member list declined. Although Macmillan remained a vegetarian in his personal life the Society's early campaign for anti-vivisection and vegetarianism was dropped and it was now supporting poor cancer patients with
meat extracts. The old emblem was also discarded. The new emblem in 1931 was a picture of a distressed woman standing outside an occupied bedroom used to reflect the pain and despair of cancer. The Society became known as the
National Society for Cancer Relief, and often shorthand,
Cancer Relief. Macmillan retired from running the organisation in 1966, in which year he moved from Sidcup back to Castle Cary. The organisation he founded has since flourished and is today known as
Macmillan Cancer Support. ==Personal life==
