Letting an immune cell do the listening: a new way to hear cancer's earliest whispers

Tumours release a fog of faint signals long before they show on a scan, but most of those signals are unknown, so tests cannot look for them. Researchers at Kumamoto University in Japan propose a different listener: human macrophages — immune cells that naturally react to their surroundings — placed in a tiny fluid device, where their measurable responses could reveal that cancer signals are present. The proof-of-concept work, published in Results in Engineering, is early, but it points toward detection that does not need to know the signal in advance.
