Beijing, Oct. 15 (Xinhuanet) -- A study of more than 117,000 Danish women provides the most convincing evidence yet of a link between a girl's growth rate and her risk of developing breast cancer later in life.
The study, published in Thursday's edition of The New England Journal of Medicine, found that women who were tall and thin by the age of 14 and those who weighed a lot at birth were more likely to develop breast cancer, China Radio International reported Thursday.
Researchers in Copenhagen looked at height and weight measurements taken from 117,415 girls born between 1930 and 1975, which they obtained from school health records.
The Danish team found that high birth weight, rapid growth around the time of mammary gland development, being tall and having low body-mass-index during adolescence were independent risk factors for breast cancer.
Specifically, they determined that girls who were about 5-feet 6-inches tall (167.5 cm) by age 14 were 50 percent more likely to develop breast cancer later in life than girls who were just under five feet (152 cm) tall at the same age.
