Most headaches are not caused by brain tumours and are quite common among healthy individuals, often stemming from various everyday triggers. However, headaches represent a prevalent symptom in brain tumours, affecting up to 60% of those with this condition at some stage.

Despite the brain lacking pain receptors, headaches associated with tumours occur due to pressure accumulation on sensitive blood vesels and nerves in the brain.

This pressure build-up might result from the tumour pressing on these vessels and nerves or obstructing the flow of the cerebrospinal flow (CSF) within the brain.
