Tailor-made treatment

A fibre-optic probe which measures the amount of oxygen in tumours may help
doctors to reduce the side effects of chemotherapy. Tumours with high oxygen
levels are more susceptible to treatment, so researchers at Mount Vernon
Hospital, Middlesex, hope the probe will allow them to identify tumours which
require less chemotherapy and radiotherapy. The probe, called Oxylite, was
invented by Oxford Optronix. Its clinical development is being funded by the
Cancer Research Fund.
