A new handheld scanner that can detect the presence of a cancerous tumor just by being waved over a person:
The device, which looks a little like the metal detectors used in airports, works because different types of body tissue resonated in different ways when exposed to a fluctuating frequency of microwaves given off by the device. This resonance can be detected because it interferes with the signal. Tumour tissue resonates at different frequencies to healthy tissue – so the presence of a cancer can be identified quickly. Normally, a patient would have to undergo a CT or MRI scan to allow doctors to spot cancer growing inside them.
