(LASVEGAS.CBSLOCAL) — Does chest size matter? For a leading genetics company, it does when it comes to predicting the likelihood of breast cancer.

For the first time, there’s a genetic link between breast size and breast cancer risks, according to a new study from 23andMe. The study, which was recently published in BMC Medical Genetics, identifies “seven single-nucleotide polymorphisms (SNPs) significantly associated with breast size, including three SNPs also correlated with breast cancer.”

The new findings come from data pulled from the survey answers of more than 16,000 23andMe customers of European ancestry.
