Question:
What causes brain tumor??
Answers:
A brain tumor is a noncancerous (benign) or cancerous (malignant) growth in the brain, whether it originates in the brain or has spread (metastasized) to the brain from another part of the body.
The cause of primary brain tumors is unknown. Primary brain tumors include any tumor that starts in the brain. Exposure to some types of radiation, head injuries, and hormone replacement therapy may be risk factors, as well as many others. The risk of using cell phones is hotly debated.
It's possible that heredity, environmental factors, viruses or other factors play a role in their development.
Some inherited conditions increase the risk of brain tumors, including neurofibromatosis, Von Hippel-Lindau syndrome, Li-Fraumeni syndrome, and Turcot's syndrome.
Tumors may occur at any age, but many specific tumors have a particular age group in which they are most common. In adults, gliomas and meningiomas are most common.
