Having a first baby in your thirties raises your risk of breast cancer for more than two decades, an overview of research has concluded.
Five years after giving birth mothers are 80 per cent more likely to get breast cancer than childless women of the same age and the risk is higher for those who start families later, it found. They have urged doctors to be alert to the problem in those with young children.
While delaying motherhood appears to increase the short-term risk, mothers still have a lower lifetime risk of breast cancer because childbirth becomes protective against the disease by the ages when most cases occur. The study found that 35 years after giving birth, mothers were 23 per cent less likely to get breast cancer than childless women of the same age.
Childbirth has previously been found to have contradictory effects on breast cancer risk, raising it initially while lowering it in the longer term, but the point where these effects cancelled each other out had been unclear.
