Two Bay Area researchers tracked the physical development of more than 400 girls, ages 6 to 8, over the course of ten years. They found that many girls are starting puberty sooner than previous generations. Early puberty has been associated with an increase in symptoms of anxiety, earlier initiation of sexual activity and may be linked with an increased risk of breast cancer.
