Radiotherapy destroys the DNA inside cancer cells to prevent them from reproducing, by using high-energy beams (x-rays) or radiation inside your body.


Radiotherapy can be used to destroy tumours, to shrink tumours before surgery, or to kill off remaining cancer cells after surgery or chemotherapy.

It is also used to treat the symptoms and control the spread of cancer when a cure is not possible.

Our partnership with cancer-care specialists GenesisCare has enhanced our radiotherapy service, giving you rapid access to pioneering technology.

There are two types of radiotherapy:

  • External beam radiotherapy: x-rays given from outside your body, using a radiotherapy machine.
  • Internal radiotherapy: a small amount of radioactive material is placed inside your body to treat cancers in your internal organs.

Both types can be given as outpatient procedures, or are carried out as part of wider inpatient cancer treatments.

MRI-Guided Linac and Varian Edge (coming spring 2020 - to replace TomoTherapy)
From spring 2020 Bupa Cromwell Hospital will have access to a new MRI-Guided Linac. We will be the first hospital in London to offer this service outside of a research study.

The MRI-Guided Linac is a technological step change in radiotherapy that significantly improves outcomes through more precise targeting of tumours, including those of the pancreas, liver, lung, prostate and breast. For most patients, it will reduce treatment time by more than half and minimise side effects.

Gamma Knife Icon (coming soon)
The Gamma Knife Icon allows doctors to provide individualised delivery, without sacrificing precision and accuracy.
