The long-term health risks of early puberty also deserve attention. It has already been demonstrated that girls who begin menstruating at a very young age have an increased risk of developing breast cancer as adults, so it is certainly possible that earlier onset of puberty may also put girls at greater risk of breast cancer. Since most girls who experience early signs of puberty do not necessarily have earlier menarche, further study is needed to determine whether they will have an increased breast cancer risk. There is research evidence that early puberty may put young girls at risk for emotional and social problems that could be devastating. Maturing young girls will have to cope with their own confusing sexual feelings as well as the impact that their maturing appearance has on boys and men.
Research indicates that girls with early menarche face consequences as young girls and as teenagers.
CPR is also partnering with other experts and organizations to help girls and their families who already must cope with this problem. Graber, J, Lewinsohn, PM, Seeley, JR, et al.
