What are the symptoms of tumours?

Symptoms of brain tumours are usually non-specific in the beginning. They also depend on the size and location of the tumour in the brain. The symptoms of a brain tumour may be varied since they may affect different functioning capacities of the brain. For example, a tumour that causes swelling of the brain may exhibit different symptoms than that which compresses the tissues of the brain.

Some of the common symptoms indicating a tumour in the brain are:
Frequent headaches that vary in intensity and time of the day. These headaches are usually intense in the mornings and ease out during the day.
Nausea or vomiting
Epileptic seizures or convulsions
Visual disturbances due to compression of the optic nerve or oedema of the optic disc (papilloedema)
Changes in memory functions
Changes in speech
Drowsiness and bouts of incoherence
Partial or local paralysis. Neurological deficits like weakness or paralysis of some parts of the body, loss of sensation, unsteadiness of gait (ataxia)
