Up to 1,000 women with one of the deadliest forms of breast cancer could have their survival chances boosted after a breakthrough by British scientists.
They discovered an existing drug may prevent cancer cells multiplying.
The women have a type of breast cancer called LAR triple negative, which is extremely difficult to treat as tumours grow so quickly.
It is responsible for two per cent of the 55,000 new breast cancer cases in the UK each year. Chemotherapy and other drugs are often ineffective.
