According to a new study, delivering an infant with a high birth weight more than doubles the risk of breast cancer. Researchers from the University Texas Medical Branch at Galveston published their findings on July 17 in the journal PLoS One.
The researchers noted that previous studies have reported that a woman’s risk of breast cancer in later life is associated with her infant’s birth weights. In view of this, the researchers set out to determine whether this association is independent of breast cancer risk factors and the mother’s own birth weight. In addition, they evaluated the association between the infant’s birth weight and hormonal environment during pregnancy. They noted that an independent association would have implications for not only understanding the mechanism of breast cancer development but also for the prediction and prevention of breast cancer.
