The relationship between the risk of breast cancer and oral contraceptive use was investigated in a case-control study conducted in France between 1983 and 1987 in five public hospitals.
Some 464 cases aged 25 to 56 years and 542 matched controls were interviewed about their history of the use of oral contraceptives (OC).
The multivariate relative risk estimate, for ever use, was 1.5 in the whole group as well as in the premeno-pausal subgroup.
However, there was no evidence that the effect varied appreciably according to duration of use, age at first use, use before first full-term pregnancy and time since first or last use.
