Around 380 people are diagnosed with primary brain tumours each year in Ireland and according to new figures released in the UK, the number of people diagnosed with brain tumours has risen by 30% in the last 20 years.
Knowing the symptoms which may indicate a problem are therefore more important than ever.
According to cancer.ie, a brain tumour is a mass - lump - formed by an abnormal growth of cells, and can cause problems if they press on the brain or grow into the brain tissue.
