We all know that breastfeeding is good for the baby, but most of us don't realise that it's also really important for the mum. 3 in 4 women don't know about the breast cancer link, while 2 in 3 don't know that breastfeeding cuts a child's chances of becoming overweight, which is a major risk factor for cancer.
The advice comes from the World Cancer Research Fund, following a survey of nearly 2,000 people. They also discovered that only 13% of men know that breastfeeding could cut a mum's risk of getting breast cancer.
And the experts are desperate to encourage women to breastfeed exclusively for the first 6 months of a baby's life and then continue once weaning starts.
'New mothers are making choices about whether to breastfeed without knowing it can help reduce cancer risk for them and their child,' said Lucie Galicie from the World Cancer Research Fund.
