・Many more women could be helped by a new type of breast cancer drug, say experts
・Biological therapies are currently only available as part of clinical trials, but hold great promise
・Experts estimate as many as one in five patients might benefit
Around 10,000 women a year in the UK might benefit from a new type of breast cancer treatment, say scientists.
Biological therapies can help fight breast cancers caused by rare, inherited genetic errors like the BRCA one actress Angelina Jolie carries.
Now a new study by experts at the Wellcome Trust Sanger Institute suggests these targeted drugs may also work in many other women who do not have these risky genes.
The drugs could be effective in one in five breast cancers, say the researchers.
