Overview
Benign brain tumours are non-cancerous growths in the brain. Although they do not spread to other parts of the body, they can still cause serious health problems by pressing on surrounding brain tissue.
Causes
The exact cause of benign brain tumours is often unknown Genetic mutations in brain cells may trigger abnormal growth Some inherited conditions, such as Li-Fraumeni syndrome, can increase risk
Symptoms
Headaches, often worse in the morning Nausea and vomiting Seizures or convulsions Vision or hearing problems Changes in personality, memory, or concentration Weakness or numbness in limbs
Diagnosis
Neurological examination to assess brain function Imaging tests such as MRI or CT scans to locate and size the tumour Biopsy in some cases to confirm the tumour type
Treatment
Observation for small, slow-growing tumours without symptoms Surgery to remove the tumour if it causes symptoms or grows Radiation therapy if surgery is risky or incomplete Medications to manage symptoms like seizures or swelling
Prognosis
Generally good with appropriate treatment Recurrence is possible depending on tumour type and location Early detection improves outcomes
Prevention & Management
No proven way to prevent benign brain tumours Regular check-ups and monitoring if at risk due to genetic conditions Prompt evaluation of new neurological symptoms is essential
