A study has showed that women with bigger breasts may be more likely to suffer breast cancer, reported the British Daily Mail on July 4.
A research team of 23andMe, genetic testing firm, said it found in the study of 16,175 European women that seven genetic mutations, called single-nucleotide polymorphisms (SNP), are associated with the bust size.
Three of the seven mutations are strongly linked to the bust cancer, according to team leader Dr. Nicholas Eriksson.
A SNP is a DNA sequence variation occurring when the location of single nucleotide ― A, T, C or G ― in the genome is changed. That’s the reason why the individual differs from others in species.
The link between breast size and risk of cancer was seen regardless of the women’s age, pregnancy and breastfeeding history and genetic ancestry in the study.
The research shows that the part of genome which normally develops breast contains hereditary factors which cause the cancer in boobs. In other words, Dr. Erickson said there is the relation between bust size and genetic structure.
