Are headaches caused by brain cancer severe?

The symptoms of late-stage brain cancer are mostly caused by tumor compression. Headaches, mental abnormalities, visual impairment and even epilepsy are all symptoms of late-stage brain tumors. Symptoms of brain cancer are mostly intermittent. Patients and their families can better cooperate with treatment by understanding the symptoms of late-stage brain cancer during treatment, and will not be at a loss when symptoms appear. So, what are the symptoms of late-stage brain tumors? Is the headache caused by brain cancer severe?

1. Headache: It is caused by increased intracranial pressure or direct compression and stimulation of the meninges, blood vessels and nerves by the tumor. It occurs in most patients in the early stage and worsens as the tumor develops to the late stage.
2. Mental symptoms: often manifested as slow reaction, laziness, decreased or even loss of recent memory, loss of self-awareness and judgment in severe cases, and may also manifest as irritability, irritability or euphoria.
3. Vomiting: It is mostly caused by increased intracranial pressure stimulating the medullary vomiting center and vagus nerve stimulation. Severe headaches are accompanied by vomiting, which is often jet-like. Children with posterior cranial fossa tumors experience vomiting early and frequently, which can be easily mistaken for gastrointestinal diseases.
4. Epileptic seizures: including generalized seizures and localized seizures. The frontal lobe is the most common, followed by the temporal lobe, parietal lobe, and the occipital lobe is the least common. Some cases have precursors before convulsions, such as temporal lobe tumors, which often have precursors such as hallucinations and dizziness before epileptic seizures. Parietal lobe tumors may cause abnormal sensations such as limb numbness before seizures.
