Girls Now Begin Puberty at Age 9

More and more girls are reaching puberty before the age of 10. The phenomenon could be linked to obesity or exposure to chemicals in the food chain.  It is putting girls at greater long-term risk of breast cancer.

A study has revealed that breast development now typically starts at an average age of 9 years and 10 months — an entire year earlier than what a similar study found in 1991.

The Times reports:

“Scientists warn that such young girls are ill-equipped to cope with sexual development when they are still at primary school … Hitting puberty early can mean longer exposure to estrogen, which is a factor in breast cancer. There is also a greater risk of heart disease.”
