Does the English Breast Screening Programme's information leaflet improve women's knowledge about mammography screening? A before and after questionnaire survey.
OBJECTIVE
To explore whether the English Breast Screening Programme's leaflet improved women's knowledge of breast cancer screening. Design Before and after postal questionnaire survey. Participants A random sample of 100 women aged between 49 and 64 years registered with GPs in Oxfordshire on whom data from a prospective, questionnaire survey was available on knowledge and perception of breast cancer screening.


RESULTS
Women's knowledge of lifetime risk had improved significantly (p < 0.0001) after the leaflet; however, the 'qualitative' interpretation of this numeric risk varied. The proportion of women who said the purpose of screening was to enable simpler treatments had increased from 34 to 45% (p = 0.05). Thirty-two per cent who had previously responded that screening prevented breast cancer now responded correctly; 20% who responded correctly before the leaflet now responded incorrectly. None of the women thought that all screen-detected cancers could be cured; 95% of the women said they were very likely to attend breast screening if invited, and the rest said they were 'fairly likely' to attend. Additional information women wanted included: what causes breast cancer; percentage rates for survival with and without mammograms; and lifestyle advice on how to avoid breast cancer.


CONCLUSIONS
Although the leaflet had improved women's knowledge of the purpose of screening in some areas, some simple messages in the leaflet had not been understood by all women.
