The discovery of a key trigger in the spread of an aggressive form of breast cancer could herald new treatments, scientists have said.
Researchers in Edinburgh have identified the cancer cell spreading role of a gene known as C35 in patients with HER2-positive breast cancer.
This type of cancer - where the HER2 protein encourages the growth of cancer cells - affects around 9,000 women in the UK and represents about 20% of all breast cancer cases.
