Chip to monitor tumours

A chip implant may soon be capable of monitoring tumours that are difficult to operate on. According to a press release, medical engineers at Technische Universitaet Muenchen have developed an electronic sensor chip that can determine the oxygen content in a patient’s tissue fluid. This data can then be wirelessly transmitted to the patient's doctor to support the choice of therapy. A drop in oxygen content in tissue surrounding a tumour indicates the tumour may be growing quickly.
