Pregnancy unlikely to reactivate breast cancer

Until now, it was believed the rush of oestrogen triggered by pregnancy would increase the risk of breast cancer recurrence.

However, findings from a case-control study, presented at the European Breast Cancer Conference in Vienna last week, have suggested that pregnancy does not affect survival for these women.

In the study of women with prior breast cancer, researchers from Brussels showed no difference in survival between those becoming pregnant and those who did not become pregnant over five years, with 30% of participants experiencing disease recurrence.

Conference chairman Professor David Cameron said that while the study may give women more confidence to have a baby, it did not provide definitive proof that there was no adverse effect from pregnancy.
