Surgeons have gained a new tool in the fight against cancer in the form of new wearable technology that allows them to visualise cancer cells in a patient using a pair of special glasses. According to a report in Science Daily, the cutting edge technology has just been used for the first time at the Washington School of Medicine. Using custom video technology in a head-mounted display combined with a targeted molecular agent that attaches to cancer cells and makes them glow when viewed through the glasses, the technology is promising a higher success rate for operations. Mutated cancer cells are notoriously tricky to spot, even when hugely magnified, and doctors have to remove surrounding tissue to see if that too is infected and possibly requires further surgery. Ryan Fields, Medical Director, said, "A limitation of surgery is that it's not always clear to the naked eye the distinction between normal tissue and cancerous tissue. With the glasses...we can better identify the tissue that mus be removed." The glasses are designed to spot cancerous tumours as small as 1 millimetre in diameter. Experts, while highlighting the need for further investigation and development is needed, have reacted to the news with excitement. Breast cancer surgeon Julie Margenthaler said, "Our hope is that this new technology will reduce or ideally eliminate the need for a second surgery."
