Variations in the risk of breast cancer associated with a family history of breast cancer according to age at onset and reproductive factors.
In a case-control study of 495 breast cancer patients and 785 controls between 20 and 56 years of age, the risk of breast cancer associated with a family history of breast cancer was studied according to age and reproductive factors.
The familial risk of breast cancer was not significantly modified by age at onset, age at menarche, number of children, age at first full-term pregnancy, menstrual cycle length or age at menopause.
However, the familial risk significantly increased with the number of abortions (p<0.05) and seemed to decrease after a natural menopause (p=0.08).
