SEX OF FIRST CHILD AS A PROGNOSTIC FACTOR FOR BREAST CANCER IN YOUNG WOMEN

Abstract
In a study in upstate New York, Incidence and survival rates of 317 young women (p < 0.05). The authors examined the effect of stage at diagnosis, interval between first pregnancy and diagnosis and concurrent pregnancy at the time of diagnosis as factors other than sex of first offspring that might have an additional influence on survival. Among these, only Interval had an effect, and it was of weak statistical significance (0.05 < p Lancet 1:415–416, 1978). Possible differences between the two studies which may account for the opposite findings are discussed.
