What is an Intracranial Neoplasm (Brain Tumour)?

Intracranial neoplasm, most commonly known as a brain tumour, often occurs when abnormal cells form within the brain. There are usually two different types of tumours, malignant or cancerous tumours and benign tumours. Cancerous tumours can usually be divided into primary tumours that have started within the brain and secondary tumours that have spread from somewhere else.


Aside from the high exposure to vinyl chloride which is highly toxic and ionizing radiation which are usually within gamma rays and x-rays, part of the electromagnetic spectrum, there are no known environmental factors associated with brain tumours. Inherited conditions may be a factor with the passing of genes throughout the generations in some patients.  Additionally, mutation and deletions of tumour suppressor genes are thought to be the cause of some forms of brain tumour. Studies have not shown any link between cell or mobile phone radiation and the occurrence of brain tumours.

Signs and Symptoms:

The signs and symptoms usually depend on the size of the tumour and also the location as well as the aggressiveness of the tumour. Symptoms of both primary and secondary brain tumours can be divided into three main categories.

  • Intracranial Pressure (often first noticed): Headaches, vomiting, nausea, altered state of consciousness, dilation of the pupil.
  • Dysfunction: Depending on the tumour location and the existing damage it may have caused to the surrounding brain structure: Cognitive and behavioral impairment (including impaired judgement, memory loss, and spatial orientation disorders), personality or emotional changes, impaired sense of smell, loss of hearing, weakness, paralysis, double vision, dizziness, speech problems.
  • Irritation: Abnormal fatigue, weariness, tremors but also epileptic seizures.

Living with a brain tumour:

It can be very difficult coping with a diagnosis of a brain tumour, both physically and emotionally.  At first it can be very frightening and confusing, but the main objective is to find out the right information about the type of brain tumour.

There are also many support groups which could help in the way of advice and a sense of community regarding the condition, the main one being Brain Tumour Research.

Here at The New Malden Diagnostic Centre we have a highly experienced team specialising  in the diagnosis and treatment of brain tumours. Our service is supported by a consultant neurosurgeon who offers surgical treatment for a full range of adult neurosurgical disorders including tumours of the brain.
