One of the country's leading centres of cancer treatment, Mount Vernon Hospital in Northwood, is about to introduce two new machines which fight the disease.
They're called "linear accelerators" and they allow more patients to be treated with precise doses of radiotherapy.
Liz Wickham reports.
The Mount Vernon cancer centre in Middlesex is welcoming two important new arrivals. The linear accelerator machines use radiotherapy to treat cancer. Mount Vernon is now the only centre in the South-East to have two of them.
The machines cost £4.5m and the centre believes it will be able to massively increase the number of patients it treats. With two machines, it will be able to keep treatment going when one of the machines is closed down for maintenance.
