Scientists Develop New Laser That Can Find and Destroy Cancer Cells in the Blood

Posted by in category: biotech/medical

Cancer cells can spread to other parts of the body through the blood. And now, researchers have developed a new kind of laser that can find and zap those tumor cells from the outside of the skin.

Though it may still be a ways away from becoming a commercial diagnostic tool, the laser is up to 1,000 times more sensitive than current methods used to detect tumor cells in blood, the researchers reported June 12 in the journal Science Translational Medicine.

To test for cancer spread, doctors typically take blood samples, but often the tests fail to find tumor cells even if they are present in a single sample, especially if the patient has an early form of cancer, said senior author Vladimir Zharov, director of the nanomedicine center at the University of Arkansas for Medical Sciences.
