New Laser Zaps and Destroys Cancer Cells in Real Time

A team of scientists from the University of ArkansasÂ have successfully tested a laser that can track down cancer cells and kill them â€” all from outside the skin.
By shining a laser at these circulating tumor cells, they end up absorbing far more heat energy than regular cells. The heat causes them to expand and collapse.
â€śThe use of lasers has revolutionized disease diagnosis and treatment. However, the large size of lasers has prevented their use in many medical applications at the cellular level,â€ť said Zharo in a 2017 statement .
And the results are promising: â€śIn one patient, we destroyed 96 percent of the tumor cells,â€ť said Zharov. And thatâ€™s before they cranked the laser to max power.
Itâ€™s not the first device of its kind, but Zharov claims itâ€™s the first to be demonstrated in humans. Dozens of devices have tried something similar, including a wrist-worn device put together by University of Michigan researchers.
But theÂ new device has another big advantage: it can scan a liter of blood in an hour â€” far quicker than competing devices.
