To fight against cancer, researchers are continuously working to find out newer ways. They are upgrading the current methods to treat cancer. Recently, researchers at the University of Tennessee’s Space Institute have developed a Femtosecond laser. Scientists are hoping to use it as a weapon against cancer.

Christian Parigger, associate professor of physics at the University of Tennessee, and his colleagues have developed a femtosecond laser which pulses at speeds of one-quadrillionth of a second. Femtosecond laser can non-invasively diagnose, map, irradiate and burn cancer cells and tumors.

Once the cancer infected area is precisely targeted, the intensity of the femtosecond laser needs to be increased only, in order to burn off a tumor. Because the laser is more exact and quicker than those used currently, this technology has the potential to treat cancer in out-vision procedure.

Lead researcher Christian Parigger said, “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.”

The technology can be especially helpful to treat brain cancer. It can easily radiate through the skull. In fact, this technique won’t heat up or damage adjacent healthy tissues. Now, researchers are working very hard to bring the system to market.
