Patients with primary brain cancers may remain asymptomatic for many years before the onset of symptoms. The variety of signs and symptoms caused by the brain cancers depend on the type, size, and location of the tumors. Benign tumors are slow growing and have a late symptom onset. Malignant tumors are infiltrative and are associated with an early onset of symptoms. People with brain cancer usually present with:

 Headaches accompanied by nausea and vomiting. These headaches are worse during the night and are associated with intracranial hypertension. Other signs may include papilledema, bradycardia, and potential for herniation.

 Seizures in more than 30% of the patients.

 Loss of vision or hearing.

 Sensory and motor problems that can manifest as numbness/tingling, muscle twitching, balance, and walking problems.

 Cognitive and behavioral dysfunction.

 Personality changes.

 Endocrine abnormalities including hypo- or hyperpituitarism.

 Fatigue and depression.
