Scientists have created a skin implant they say could one day be used to help detect some of the most common cancers.
It works by looking for elevated levels of calcium in the blood, which is linked to some cancers.
When these levels go above a threshold, a response is triggered by the implant, leading the skin to form a brown mole.
Scientists say the technology could eventually help to diagnose cancer earlier, but experts say the research is still in its "early days".
