Brain Tumours 1
Brain Tumours
Brain tumours are a growth of cells that multiply in an abnormal uncontrollable way. Brain tumours are graded according to how fast they grow and how likely they are to grow back after treatment. Grade 1 and 2 are low grade and 3 and 4 are high grade.
There are 2 main types of brain tumours:
• Non-cancerous (benign) brain tumours- these are low grade (1 or 2) which means they grow slowly and are less likely to return after treatment
• Cancerous (malignant) brain tumours- these are high grade (3 and 4) and either start in the brain (primary tumours) or spread into the brain from elsewhere (secondary tumours) and are more likely to grow back after treatment.
The symptoms of a brain tumour vary depending on the exact part of the brain affected. Common symptoms include:
• Headaches
• Seizures
• Persistently feeling sick, being sick and drowsiness
• Mental or behavioural changes, such as memory problems or changes in personality
• Progressive weakness or paralysis on one side of the body
• Vision or speech problems
