Scientists Develop New Laser To Remove Cancer Without Damaging Healthy Tissue
Good news! Scientists at Heriot-Watt University in Edinburgh have developed a system of ultra fast lasers that have the ability to remove cancerous cells while leaving healthy cells unharmed. The lasers deliver pulses that are one trillionth of a second long to precisely target cancerous cells in the lab. Since the pulses are so short they do not have enough time to burn or damage the tissue surrounding the targeted cells.
The experiments led by Professor Jonathan Shephard have focused on colorectal cancers and have not been attempted on human patients, but the unique approach is encouraging. The team plans to further develop and test this new system over the next three years.
