Infra-red light could detect early cancer signs
A new endoscope uses near-infrared light to spot the warning signs of oesophageal cancer
Scientists have developed an endoscope that can distinguish between light emitted by healthy and abnormal cells.
The instrument uses near-infrared light to spot early warning signs of oesophageal cancer, the fourth most common cause of cancer death in men in the UK.
Researchers at the Cancer Research UK Cambridge Institute sprayed a dye on oesophageal tissue samples taken from people with Barrett’s oesophagus, a condition that increases the risk of developing oesophageal cancer. The dye sticks to healthy cells but not pre-cancerous cells.
The use of near-infrared light makes it possible to differentiate between healthy and abnormal cells in a way visible light cannot, the researchers said.
‘Removing patches of pre-cancerous cells could prevent some cases of oesophageal cancer. But we...
