A brain tumour is a development of brain cells that multiply abnormally and uncontrollably. If you experience any of the following symptoms, especially a severe and ongoing headache, consult your doctor immediately. Even though you might not have a brain tumour, these symptoms need to be investigated.
If a brain tumour originated in the brain, it is referred to as a primary tumour. If they originated elsewhere in your body and then spread to your brain, they are regarded as secondary.
