The possible relationship between breastfeeding and risk of breast cancer was assessed in a multinational hospital-based case-control study that was conducted from 1979 to 1986 in 10 countries, including some in which many women lactated for long periods of time.
Data were collected by personal interviews of 2336 cases and 14900 controls.
No statistically significant trends in relative risk estimates with duration of lactation were observed in all women combined, in women who were pre- or postmenopausal, in women of various ages at diagnosis, in women with different numbers of livebirths, or in women characterized by the presence or absence of other risk factors for breast cancer.
