Large breasts 'increase the risk of cancer'
Women with a large bust could be more likely to develop breast cancer, scientists have said.
Research conducted on 16,000 women found genetic mutations associated with breast size were also linked to cancer.
Previous studies have connected the amount of non-fat breast tissue to an increased risk but found little evidence of a link with breast size.
Dr Nicholas Eriksson of US genetics firm 23andMe said the latest research was the first to establish a substantial link between breast size and cancer but added further studies were needed to back up the findings.
