Pregnancy 'does not increase risk of breast cancer returning'

21 March 2012

Women who have been treated for breast cancer have no worries about the disease returning after a pregnancy.

Previous research has suggested that the surge of hormones which women encounter during labour could trigger the cancer to emerge once more.

Now though, Dr Hatem Azim, a medical oncologist at the Jules Bordet Institute in Brussels, has led a new study which highlights that there is no difference in the survival rates of pregnant women who once fought breast cancer compared to those who have not delivered a baby after battling the disease.

The scientist followed 333 females who had become pregnant after being diagnosed with the condition and compared them to 874 women who had not gone into labour to record the results.

Dr Azim commented: "Out of all the women, 57 per cent had ER+ disease, but the study showed there was no difference in the length of time women with either ER+ or ER negative disease survived without their disease recurring compared with those who did not become pregnant."

Robert Marsh, the chief executive of The Eve Appeal, recently stated that pregnancy and breastfeeding are two experiences which can reduce the chance of a woman suffering from ovarian cancer.
