Sticky cell fingers help keep breast tumours contained

    Researchers at Turku University and Åbo Akademi University, Finland, have identified that finger-like cellular extensions called filopodia contribute to building a barrier surrounding breast tumours.

This early disease stage is typically not life-threatening, as surgery can remove the tumour. However, breast cancer can become lethal if it spreads and forms metastases.
