What symptoms possibly indicate a brain tumour?

Many people fear having a brain tumour. Recurring headaches of increasing intensity can be a sign of a brain tumour, as can morning nausea and vomiting without any indication of a gastrointestinal illness. Frequently, however, the symptoms are seizures or spontaneous convulsions, vision problems or neurological functional losses, such as paralysis, sensory disturbances, coordination problems, cognitive impairment or personality changes.
