Infertility could increase the chance of cancer in mid-life by almost a fifth, research suggests.
The reporting here, actually quite good.
But the four-year study of women who were in their 30s when monitoring began, found that those who suffered infertility problems were 18 per cent more likely to develop any type of cancer during the period.
Researchers stressed that the overall risk of cancer at this stage in life remained low.
Overall, those with fertility problems had an absolute risk of 2 per cent, compared with that of 1.7 per cent among other women.
However, I wonder.
During the follow-up period there were 1,310 cancers diagnosed among the infertile women and 53,116 among the control group of women who were not infertile.
Breast cancer was the most common cancer in both groups.
The single largest risk factor for breast cancer is – I think I recall at least – not having brought a child to term and then nursed it.
So, I wonder, I wonder If we run this again with the infertile – presumably, those with no children – against the fertile but exclude those who already have children?
