Usually brain tumours that result in terminal cancer have been ignored over a large time frame. Though it is very likely that the patient would not visit the doctor even after experiencing symptoms like nausea, vomiting, imbalance of the body, impairment in speech, vision and hearing; it is possible that the patient stopped responding to the treatment administered.
It is crucial to understand what causes terminal brain cancer and who is at risk as scientifically, doctors have not been able to pick out exact causes of terminal brain tumour. It is clarified that brain tumours are not contagious. But certain causes and risk factors have been recorded.
Causes of Terminal Cancer
- Direct Cause
The direct cause refers to a situation where in the cancer cells travel towards the brain from different parts of the body through the lymphatic system or the bloodstream and multiply such that there it is a visibly large mass of tumour accumulated in the brain.
- Metastasis Sources
Metastasis cancer is cancer that has spread from its site of origin to other body parts. Cancer can spread through local invasion, wherein, cancer cells invade the local tissue or through intravasation, circulation or proliferation.
- Exposure to Radiation
Numerous sources reveal that the exposure to radiation is a major source of cancer development in the brain. Exposure to radiation as an infant or exposure to higher doses of radiation will lead to terminal brain cancer.
- Environmental Considerations
Over exposure to cigarette smoke, aspartame and highly toxic chemicals may lead to terminal brain cancer.
Risk factors of terminal brain cancer
- Gender
Men are more likely to develop secondary brain tumours that result in terminal brain cancer as compared to women.
- Age
A majority of the cases of terminal brain cancer are detected in individuals over 70 years of age. But, numerous children below the age of 8 are diagnosed with leukaemia, the most common form of cancer in children.
- Race
It has been noticed that terminal brain cancer is more predominant amongst the white races as compared to other races.
- Family History
People, whose relatives are diagnosed with brain cancer, have higher chances of developing brain tumour as well. Though this is not a heredity disease, it is an influencing factor.
More than 17,000 people in the US are diagnosed with cancer every year. Malignant cancer accounts for 2% of cancers diagnosed in the US and leads to over 13,000 deaths

What is brain tumour?
Brain tumour is a type of cancer that breeds in the brain. The brain is a soft and spongy organ present inside the skull. The bones of the skull protect the brain from injury. The brain is covered by three thin membranes called meninges; and fluid called cerebrospinal fluid. The fluid cushions the brain and protects it. The cerebrospinal fluid (CSF) is present around the spinal cord as well. The CSF flows through the spaces between the meninges, spaces within the brain called ventricles and the spinal cord. The brain controls all the functions of the body such as walking and ...

Single Gene Defect causes Brain Tumour in Children
Brain tumour that usually affects children grows slowly and is benign in nature. However, it takes more than one approach of treatment to get rid of the tumour from the brain. Now researchers have found that a single gene defect is enough to cause brain tumour in children. This form of tumour is also known as pilocytic astrocytomas. The gene whose defect leads to brain tumour in children is BRAF or GTPase regulator associated with the focal adhesion kinase. In case of a brain tumour a cellular signalling pathway is created which is active in healthy minds only when needed. ...
