Background. Education of women to perform breast self-examination is a main
objective of cancer societies worldwide. Methods. By means of a questionna
ire, 975 healthy women in an Austria-wide population based cross-sectional
study were asked about their knowledge of breast self-examination (BSE) and
mammography, and their cancer histories. Results. 92% of the women knew BS
E but only 31% practiced it thoroughly. Women living in rural communities w
ith a life companion and younger women were more likely to practice BSE. Wo
men who had family histories of cancer, especially older women, performed B
SE significantly more often. There was a trend towards increasing BSE with
increasing personal perception of the risk of cancer, especially among olde
r women. The study showed a positive association between BSE and screening
mammography. Conclusions. Although knowledge of BSE is widespread, it is ac
tually practiced by only one third of women. Older women but not young wome
n carry out BSE significantly more often when they have family histories of
cancer. Information campaigns should target specific groups and emphasize
the effectiveness of properly done BSE.
