Introduction
Doctors describe meningioma cancer as a tumor that develops from the meninges, the protective layers surrounding the brain and spinal cord. Most tumors grow slowly and remain non-cancerous, yet some forms behave aggressively and threaten nearby brain tissue. Because the brain controls every body function, early medical evaluation becomes extremely important. In certain cases, doctors may also use an Electroencephalogram to assess seizure activity linked to tumor irritation.
Global Statistics
Across the world, meningioma ranks as the most common primary brain tumor in adults. Studies show that about 30–35% of all brain tumors fall into this category. Women develop this tumor more often than men, which suggests hormonal influence. Risk also rises after the age of 40. Slow growth often delays symptom appearance, so many people remain unaware for years.
Causes
Scientists continue to study the exact cause, yet several risk factors show strong links. Radiation exposure to the head during childhood increases long-term risk. Genetic conditions like Neurofibromatosis type 2 raise susceptibility. Hormonal changes may encourage tumor growth, which explains higher rates in women. Aging also plays a major role. Family history sometimes contributes as well.
Symptoms
Tumor location determines the warning signs a person experiences. Persistent headaches often develop first. Seizures may occur when the tumor irritates brain tissue, and doctors sometimes order an Electroencephalogram to study abnormal brain wave patterns. Vision problems can arise if the tumor presses on optic nerves. Memory difficulties, speech issues, or hearing loss may follow depending on the affected brain area. Weakness on one side of the body and personality changes can also appear.
Types of Meningioma
Doctors classify meningiomas into three grades based on growth behavior.
Benign Meningioma
Slow growth and high treatment success rates define this common type.
Atypical Meningioma
Moderate growth and higher recurrence risk characterize this group.
Malignant (Anaplastic) Meningioma
Rapid spread and aggressive invasion make this type more dangerous
Diagnostic Tests
Accurate diagnosis requires detailed brain imaging and neurological evaluation.MRI scans provide the clearest images of tumor size and location. CT scans help detect bone involvement. Surgeons may perform a biopsy to confirm tumor type. Neurological exams check reflexes, strength, and coordination. When seizures occur, specialists may use an Electroencephalogram to evaluate electrical brain activity. Doctors sometimes repeat the Electroencephalogram during follow-up care if seizure symptoms continue.
Prevention and Risk Reduction
No method guarantees full prevention, yet healthy habits may reduce risk.Limiting unnecessary radiation exposure protects brain tissue. Balanced nutrition and regular exercise support overall brain health. Medical guidance before hormone therapy helps reduce hormonal influence. Prompt evaluation of long-term headaches or seizures allows early detection. Routine health check-ups improve the chance of finding tumors before complications arise.
Conclusion
Meningioma cancer often progresses slowly, yet neglect can lead to serious neurological problems. Early diagnosis and modern treatment give many patients a positive outcome. Seizure-related symptoms sometimes require monitoring with an EEG as part of a broader neurological assessment. Timely specialist care greatly improves long-term quality of life, and doctors may recommend an Electroencephalogram again if symptoms change.

1. Is meningioma always cancerous?
No, most meningiomas are benign, but some types grow aggressively and require urgent treatment.
2. Can meningioma cause seizures?
Yes, tumors that irritate brain tissue may trigger seizures, and doctors may use an Electroencephalogram to investigate abnormal brain activity.
3. What is the best test to detect meningioma?
MRI remains the most accurate imaging test for detecting and evaluating meningioma tumors.
