New genetic variants contribute to the risk of breast cancer in women, study reveals

A new study reveals seventy-two novel genetic variants that are responsible for breast cancer risk. Published in the journals Nature and Nature Genetics, of these 72 variants, 65 are common variants that predispose patients to breast cancer and a further seven variants predispose particularly to estrogen -receptor negative breast cancer - the subcategory of cases that do not respond to hormonal treatments.
