Brain tumours are the most life-disrupting trouble of human beings. Usually, it is accompanied by extreme headaches, vertigo, personality changes, and balance problems. It is unpredictable. Even benign brain tumours can be deadly if not treated in time. The important reason that makes brain tumours more dangerous is its location. As every part of the brain is relevant, significant and useful, tumour in any part of the brain has significant potential for causing some harm to the patient. As the brain lives within the skull so there is no place for any kind of expansion.
A brain tumour is a growth of abnormal cells in the brain. Tumours start from other body parts and later spread to the brain are known as malignant (metastatic) brain tumours. Malignant tumours or Cancerous tumours are rapidly growing and aggressive. While on the other side, benign tumours are slow-growing and non-aggressive.
A few types of brain tumours are as follows:-
Signs and symptoms of a brain tumour depend on its size, place, and rate of growth. Few symptoms are as follows:-
Few treatments are as follows:-
1. Surgery: During surgery, the tumour among some healthy tissues can be removed (this procedure called a craniotomy). Removal of a tumour can improve the neurological symptom, provides tissues for further diagnosis, and helps in the effective treatment of other tumours. A neurosurgeon has a specialization in the brain and spinal column surgery. Some methods are being used in surgery are as follows:
In surgery, some part of the skull gets removed. Once the surgery gets completed then some part of a patient’s bone is used to cover the skull.
2. Radiation Therapy: The use of high-energy X-Ray to destroy tumour cells is known as Radiation Therapy. To slow or stop the growth of brain tumour radiation therapy can be used. Specialized doctors for radiation therapy for the tumour are known as a radiation oncologist. External-beam radiation therapy is the most common type of radiation treatment that is given outside of the body from a machine. When radiation treatment is given by implants, it is called internal radiation therapy or Brachytherapy. A few types of external radiation therapy are as follows.
3. Medication therapies: Medication therapies can be used some time to treat tumour cells. The Bloodstream is used for this treatment. Neuro-oncologists and medical oncologists are specialized for tumour treatment by medication therapies. Chemotherapy and Targeted therapy are types of medication therapies.
In most of the cases of the primary brain tumours, the cause of the tumour is not clear. But there are some factors which may increase the risk of it.
