Younger mothers are healthier. A fresh report from the Norwegian Institute for Public Health (Folkehelseinstituttet) shows that older women who give birth to a child with Down’s syndrome have a 23 percent higher risk of developing breast cancer.

Crucial

The hormone, human chorionic gonadotropin (hCG), is made soon after conception by the developing embryo. Research has found that its presence is vital, and is thought to affect the immune system’s tolerance for being pregnant.

But women who produce a child with the syndrome have higher levels of the hormone. Younger mothers, meanwhile, have an increased long-term resistance to developing breast cancer.

Increased resistance

The findings have surprised researchers.

“You would have thought that these women were better protected against breast cancer than mothers of healthy children,” says professor Tone Bjørge at the University of Bergen.

Her findings show that the danger of developing breast cancer was limited mainly to women under 50 and those over 30. The risk was also greater if a woman had had at least one healthy child before becoming pregnant with a child with Down’s syndrome.

Bjørge and the other researchers are the first to have compared the rates of breast cancer and Down’s syndrome respectively, based on 5.2 million healthy children worldwide.
