Brain Tumours

Brain tumours are among the cancers with the worst outlook and are hard to treat owing to factors such as inoperable locations in the brain and the difficulty of developing drugs that can cross the blood-brain barrier.

Stereotactic radiosurgery – using focused beams of radiation to treat tumours and other abnormalities – was the brainchild of Swedish neurosurgeon, Lars Leksell. It has become widely deployed to treat brain metastases with a machine that bears his name – the Leksell Gamma Knife.
