Our interest is swelling: a collaborative venture to establish the world's first free public screening for lymphoedema.

This article describes the collaborative processes involved in the implementation of a free public health screening program for people at risk of lymphoedema following the removal of lymph nodes during surgery to control breast, prostate and other cancers, or injury. The planning phase of the program is described with emphasis on the need to secure a well situated venue, the commitment of a cohort of key health professionals, service club and lay volunteers, and the need to carefully target and publicise the event widely. The implementation phase requires careful consideration of the physical layout of the event, the direction and management of the flow of human traffic, information and equipment requirements, and recognition that screening programs place people in vulnerable positions. Effective communication skills are essential, as is a knowledge of where people can be referred should the need arise. A budget is provided together with discussion regarding the success of the program and recommendations for future consideration such as the need to target men to attend screening and for long term follow up of the outcomes.
