The discovery of a gene could herald new treatments for thousands of medical alert wearers.
Edinburgh scientists have been studying a disease known as HER2 positive breast cancer, an aggressive form which grows and spreads more quickly than other forms. They believe they have found a gene which triggers the spread of the disease, which represents about 20% of all breast cancer cases.
At the moment it is treated with the drug herceptin, which prevents the cancer cells multiplying. Scientists hope this discovery will help them develop a new treatment.
Research leader Dr Elad Katz, of the Breakthrough Breast Cancer Research Unit, said: "We are at an early stage but there is now a real possibility there could be a new treatment for women with HER2-positive breast cancer."
