What is stereotactic ablative radiation therapy (SABR)?

SABR targets tumours in the body with high doses of radiation therapy. It destroys cancer cells with minimum damage to surrounding healthy tissues.

  • You might be offered SABR instead of surgery
  • It’s used to treat lung, spine, liver and bone tumours and tumours in individual lymph nodes
  • It offers some patients longer disease and symptom control and improved quality of life
  • It may use ‘rotational radiation therapy’ (VMAT) to focus a high dose of radiation to the tumour
  • Surrounding healthy tissue receives a lower dose, minimising the risks of side-effects
  • Targeted treatment means that SABR is effective and usually over quickly – just three to eight sessions
