Symptoms of brain tumours


Symptoms of brain tumours may be caused either by the tumour itself or by the impact of pressure caused by swelling in the brain. The location of the tumour, or where the pressure occurs, determines the type of symptoms.

The most common symptoms are headaches and seizures (fits). These symptoms can be caused by many conditions other than brain tumours but it is important to go to your GP as soon as possible, to make sure.
