Records of the London breast cancer support charity
were examined, identifying attendees at a total of 13 lymphoedema
awareness classes (see Fig. 1). Women were
excluded if they could not be contacted, were deceased,
not well enough to participate, or had attended a class
not taught by the author (EJ). As it was likely that, unbeknownst
to the charity, some women were deceased or
suffering from progressive disease (Cancer Research UK
2015), we requested individual primary care providers
(GPs) to confirm whether their patient was well enough
to participate; 83 GPs (91 %) responded (see Fig. 1).
