Brain cancer
Symptoms and causes
Symptoms and causesThe brain
The brain's functions are:
- to regulate the functioning of our body
- to collect all information
- to coordinate commands for our body
- essential for vision, hearing, smelling, thinking, feeling, speaking and moving
- essential for knowing what is going on inside and outside our body
The brain, the spinal cord and the nerves together form the nervous system. We divide the nervous system into the central nervous system (the brain and the spinal cord) and the peripheral nervous system (the nerves).
What is it?
A brain tumour arises in the central nervous system: the brain or the spinal cord. The brain consists of nerve cells, called neurons, and supportive cells called glial cells. Most brain tumours occur in the glial cells. The brain is covered by three thin layers of tissue: the meninges. A tumour may also form there. This tumour is located outside of the brain but inside the cranium. The spinal cord connects the brain to the rest of the body. It is also covered with membranes. Rarely does a tumour arise in the spinal cord or spinal cord membrane.
The World Health Organization (WHO) reports that there are 120 types of these sorts of tumours in the central nervous system. The two most common are gliomas and meningiomas.
Gliomas
are extremely slow-growing and well-defined growths.
are also still slow-growing but much less sharply aligned. They can sometimes develop over the course of years without the person presenting any symptoms. Recurrence is possible after treatment; in approximately 50% of the cases, they recur as a grade 3.
grow and spread very quickly and often do not respond well to treatments.
Meningiomas
A meningioma arises in the brain or spinal fluid meninges. There are three grades of meningioma:
are the most common and do not contain malignant cells
Symptoms
The following complaints or symptoms may indicate a brain tumour:
| Recurrent headache | Vomiting | Nausea |
| Speech changes | Reduced vision or hearing | Balance problems |
| Mood fluctuations | Behaviour and personality changes | Trouble concentrating or with coordination |
| Memory loss | Muscle twitches | Tingling or numbness in the arms or legs |
| Epileptic attacks |
Diagnosis and treatment
Diagnosis and treatmentTreatment
Treatment for a brain tumour may consist of oncological surgery, radiation therapy and targeted therapy.
The attending physician may ask a patient to participate in scientific research (also called a clinical study or trial). For patients, participation in a study often represents an additional treatment option. In clinical trials, physicians test whether a new drug or treatment is safe and produces better results than existing treatments. However, a patient will only participate if he or she provides his or her express consent.
