'Don't take a chance': a public campaign to encourage the early reporting of breast symptoms.

As part of a study to evaluate health education about breast cancer, a campaign to encourage the early reporting of breast symptoms was organised jointly by Community Medicine, University of Southampton and Southampton Health Education Service. A thorough account of all aspects of the preparation and implementation of the campaign is presented. It is hoped that other organisations, considering a similar campaign, could utilise the materials specially produced to convey our message and benefit from our experiences.
