Causes
1. Primary brain tumor
The brain tumors that originate in the brain itself or in the tissues near to it, such as meninges, pineal gland, cranial nerves, pituitary gland, are called as primary brain tumors. The main cause is when the normal cells undergo some mutations in their DNA, allowing the cells to grow and divide at a high speed-rate. Although the incidences of adults having to develop primary brain tumors are far less common that the secondary brain tumors
There are several types of the primary brain tumor, and they all get their names from the kind of cell that is involved in the tumour. The types are:
Gliomas.
Meningiomas.
Acoustic neuromas (schwannomas)
Pituitary adenomas
Medulloblastomas
Germ cell tumours
Craniopharyngiomas
2. Secondary brain tumor
This brain tumor is metastatic in nature and result from the cancer that starts from any other part in the body and then spreads to the brain. These would most often occur in people who have a medical history of cancer.
The common cancer types include:
Colon cancer
Kidney cancer
Lung cancer
Melanoma
Risk factors
The exact cause of people having primary brain tumor is still not clear with the specialists although there are some factors that affect or can increase the risk of a brain tumor.
These risk factors will include:
Exposure to radiation.
Family history of brain tumor
