Advanced bowel cancer cells have very few “molecular flags” on their surface, helping to explain why they may be hard for the immune system to detect, a new study has shown. Molecules on the surface of tumor cells, arising from faults in their DNA, help the immune system pick them out as cancerous—enabling immune cells
