Breast cancer is the commonest malignancy diagnosed in women worldwide and accounts for over 30% of all cancers diagnosed in women in the United Kingdom.1 The average lifetime risk of developing breast cancer for women in the United Kingdom and United States is estimated to be 12%, although this may
be an overestimate, as it is not clear what age this assumes a woman lives to and whether full adjustment has been made for those who die young from other causes. It is also unclear whether multiple breast cancers in a single woman are counted as several women with breast cancer.
