Pen guides surgeon to cancer cells
In cancer surgery, it is often hard for the surgeon to distinguish between cancer tissue and healthy tissue, but with a new pen, the doctor only needs to point at tissue during surgery to learn if it is cancerous. The pen emits a water drop, which dissolves the molecules liberated by cancer cells. The drop is immediately analysed by a mass spectrometer, that gives the answer in a matter of seconds. The pen has diagnosed tissue samples of lung cancer, breast cancer, etc., at an accuracy of 96 per cent. It will be used in surgery this year.
