What is a brain tumor?
A brain tumor is a growth within the skull.
A brain tumor is a growth that develops within the skull due to abnormal cell growth. The origin of these cells varies widely.
The cells can originate from nerve tissue, connective tissue, meninges, certain glands... but they can also arise from diseases elsewhere in the body, where cells break away and can enter the brain via the bloodstream. The spinal cord can also be affected.
