  1. Breast cancer incidence subsequent to surgical reduction of the female breast.

    Article - En anglais

    The incidence of breast cancer among 1240 women who were treated surgically for breast hypertrophy in Copenhagen, Denmark between 1943 and 1971 was determined and compared with age-and calendar period-specific rates for the Danish female population.

    A total of 32 cases of breast cancer had developed by the end of 1990 ; the expected number was 52.55, yielding a relative risk (RR) of 0.61 [95% confidence interval (CI) 0.42-0.86]. The greatest reduction in risk was observed for women who had 600 g or more of breast tissue removed (RR=0.30 ; 95% CI 0.10-0.69).

    This suggests that the number of potential foci is important for cancer development in the female breast.

    In the group of women who were operated on before the age of 20, four cases of breast cancer developed, compared with 2.23 expected cases, to give an RR of 1.79, suggesting that the aetiology of their breast hypertrophy may be different from that for the rest of the group.
