Scientists in the US have developed a laser that can locate, map, and then precisely destroy cancer tumors non-invasively.

Using a "femtosecond laser" that pulses at speeds of one-quadrillionth of a second, the new "seek and destroy" device focuses on a specific tissue region to find and precisely map a tumor.

The new technology is the creation of Christian Parigger, associate professor of physics, and Jacqueline Johnson, associate professor of mechanical, aerospace, and biomedical engineering, both of University of Tennessee Space Institute in Tullahoma, along with Robert Splinter of Splinter Consultants.

Parigger says in a statement released earlier this week:

"Using ultra-short light pulses gives us the ability to focus in a well confined region and the ability for intense radiation."

"This allows us to come in and leave a specific area quickly so we can diagnose and attack tumorous cells fast," he adds.

Once the laser finds the cancerous area and has it precisely targeted, all that is needed is for the radiation intensity to be turned up to burn off the tumor.
