Abbreviation: CI=confidence interval.
a
A woman was considered breast cancer aware if she: identified at least five non-lump symptoms; identified that a 70-year-old woman is most at risk of breast cancer (rather than a 30-year-old, a 50-year-old or a woman of any age); and reported checking her breasts at least once a month.
