A study has disclosed that increasing number of girls are touching puberty line before the age of 10.
Specialists think that the development might be related to chemicals in the food chain and they dread that it may result in more sexual activity amongst children and an amplified possibility of breast cancer.
The research showed that breast development in cases of 1,000 girls began at an average age of nine years and 10 months, a year previous than when alike study was conducted in 1991.
It increases the problem of girls having to deal with sexual maturity, whilst still at primary school.
Anders Juul, of the University Hospital in Copenhagen, said, "We were very surprised. If girls mature early, they run into teenage problems at an early age and they're more prone to diseases later on. We should be worried, regardless of what we think the underlying reasons might be”.
Anders said that it's an obvious indication, whether it's fast food, ecological chemicals or dearth of physical movement.
The study was performed in Denmark in 2006. But it is believed that the drift also concerns the UK.
Premature puberty can imply longer contact with oestrogen, which is a cause in breast cancer.
