Is Meningioma Cancer?
Table of Contents
Meningiomas are tumors that develop from the membrane tissues called the meninges, which surround the brain and spinal cord. Meningiomas, one of the most common types of brain tumors, often lead patients who receive this diagnosis to ask the same question: “Is meningioma cancer?” In particular, people diagnosed with meningioma after an MRI or CT scan may wonder whether hearing the word “tumor” directly means cancer.
In fact, the vast majority of meningiomas are benign and are not considered cancer in the conventional sense. However, some types of meningiomas may show more aggressive characteristics and therefore require close monitoring. Whether a meningioma is cancerous is determined according to the grade, cellular structure, and growth behavior of the tumor.
What Is a Meningioma?
A meningioma is a tumor that originates from the meningeal membranes that protect the brain and spinal cord. These tumors do not develop directly from brain tissue but from the membrane layer surrounding the brain.
Most meningiomas grow slowly and may remain without symptoms for years. Today, thanks to advanced imaging methods, many meningiomas are detected incidentally.
In some patients, however, various neurological symptoms may develop as the tumor grows.
What Are the Symptoms of Meningioma?
- Persistent headache
- Visual disturbances
- Double vision
- Loss of balance
- Hearing problems
- Memory problems
- Seizures
- Weakness in the arms or legs
Symptoms may vary depending on the size and location of the tumor.
Is Meningioma Cancer?
The answer to this question varies depending on the type of meningioma.
The vast majority of meningiomas are benign tumors and are not considered cancer. This is because these tumors generally grow slowly, do not aggressively invade surrounding tissues, and do not metastasize to distant organs.
However, not all meningiomas should be considered completely harmless. Some meningiomas can cause serious health problems because of their location.
Prof. Dr. Ömür Günaldı states that most meningiomas are benign, but every tumor should be evaluated in detail.
What Are the Grades of Meningioma?
One of the most important factors determining whether a meningioma has cancerous characteristics is the grade of the tumor.
Grade 1 Meningioma
This is the most common type of meningioma.
It accounts for the majority of all cases and is considered benign.
It grows slowly, and when completely removed surgically, long-term outcomes are generally very successful.
Grade 2 Meningioma
This is known as an atypical meningioma.
It may grow faster than Grade 1 meningiomas and has a higher risk of recurrence.
Therefore, it requires closer follow-up.
Grade 3 Meningioma
This is defined as an anaplastic or malignant meningioma.
Although rare, it is the most aggressive type.
Meningiomas in this group may show certain cancerous characteristics and may require more intensive treatment.
Why Is Meningioma Confused With Cancer?
Many people diagnosed with meningioma assume that the word “tumor” means cancer.
However, in medicine, not every tumor is cancer.
Benign Tumors
- Grow slowly
- Have a limited effect on surrounding tissues
- Do not metastasize
Malignant Tumors
- Grow rapidly
- May spread into surrounding tissues
- Have a higher risk of recurrence
The majority of meningiomas belong to the first group.
Can Meningioma Be Dangerous?
Not being cancerous does not always mean that a meningioma is harmless.
Even some benign meningiomas can cause serious health problems because of their location.
Location Near the Brainstem
Meningiomas that put pressure on the brainstem may affect vital functions.
Location Near the Optic Nerves
Vision loss or visual field disturbances may occur.
Location Near Motor Areas
Weakness in the arms or legs may develop.
Therefore, the fact that a tumor is benign is not sufficient on its own for a complete evaluation.
How Is Meningioma Diagnosed?
Imaging methods play an important role in the diagnosis of meningioma.
Magnetic Resonance Imaging (MRI)
It provides detailed information about the size and location of the meningioma.
Computed Tomography (CT)
It is particularly useful for evaluating the relationship between the tumor and bone structures.
Pathological Examination
The grade of the tumor is determined by examining a tissue sample obtained after surgery.
A definitive diagnosis is made based on pathological evaluation.
Prof. Dr. Ömür Günaldı emphasizes that whether a meningioma is benign or malignant can only be clearly determined after a detailed evaluation.
How Is Meningioma Treated?
The treatment method is determined according to the size, location, and grade of the tumor.
Surgical Treatment
It is the most commonly preferred treatment method.
The aim is to remove the tumor as safely and completely as possible.
Radiotherapy
It may be used for meningiomas that cannot be completely removed or that have a high risk of recurrence.
Follow-Up
Some small meningiomas that do not cause symptoms may be monitored with regular MRI examinations.
What Is the Life Expectancy of Patients With Meningioma?
Life expectancy is generally very favorable in patients with benign meningiomas.
After successful treatment, the majority of patients can return to their normal lives.
Factors affecting life expectancy include:
- Tumor grade
- Tumor location
- Patient’s age
- Treatment success
- Regular follow-up
Early diagnosis and appropriate treatment positively affect long-term outcomes.
Can Meningioma Recur?
Some meningiomas may recur after treatment.
- Grade 2 meningiomas
- Grade 3 meningiomas
- Tumors that cannot be completely removed
carry a higher risk of recurrence.
Therefore, regular MRI examinations are extremely important.
Prof. Dr. Ömür Günaldı states that keeping patients under long-term follow-up after meningioma treatment is critical for early intervention.
The vast majority of meningiomas are benign tumors and are not considered cancer in the conventional sense. However, some types of meningiomas may behave more aggressively and require close monitoring. The grade, location, and biological characteristics of the tumor are among the most important factors determining the treatment plan. With early diagnosis, appropriate treatment, and regular follow-up, the majority of patients with meningioma can maintain a healthy life. Comprehensive evaluations and personalized treatment plans provided by Prof. Dr. Ömür Günaldı offer important advantages throughout the treatment process for patients with meningioma.
