Can a Meningioma Go Away on Its Own?

When a person is diagnosed with a meningioma, one of the first questions that comes to mind is, “Can a meningioma go away on its own?” Many people who are unfamiliar with brain tumors wonder whether the tumor may shrink over time or disappear without treatment. Although meningiomas are generally considered slow-growing tumors, it is very rare for them to disappear completely on their own.

Not every meningioma behaves in the same way. Some may remain the same size for years, while others may continue to grow. Therefore, regular monitoring is extremely important for patients diagnosed with meningioma. Prof. Dr. Ömür Günaldı, an experienced specialist in neurosurgery, emphasizes that meningiomas should be evaluated individually and that treatment decisions should be based on the characteristics of the tumor.

What Is a Meningioma?

A meningioma is a tumor that develops from the meninges, the membranes surrounding the brain and spinal cord. It is one of the most common types of primary brain tumors.

Although most meningiomas are benign, they can still cause significant neurological problems depending on their location. Therefore, the term “benign” does not necessarily mean that the tumor is harmless.

Is a Meningioma Brain Cancer?

The majority of meningiomas are benign and are not generally considered brain cancer in the traditional sense. However, certain aggressive subtypes may grow more rapidly and affect surrounding tissues.

Can a Meningioma Go Away on Its Own?

The short answer is generally no.

Meningiomas usually do not disappear completely on their own. In some cases, their growth may stop, or the tumor may remain the same size for a long period. However, complete spontaneous disappearance of the existing tumor tissue is very rare.

For this reason, diagnosed meningiomas should be monitored regularly because their growth rate can vary from one patient to another.

Prof. Dr. Ömür Günaldı emphasizes that skipping follow-up examinations based on the assumption that a meningioma will disappear on its own may carry significant risks.

Can a Meningioma Remain Stable Without Growing?

Yes.

Some meningiomas may remain the same size for years without showing significant growth. This is particularly common with small tumors that are discovered incidentally.

In such cases, doctors may recommend an active monitoring approach.

• Regular MRI scans are performed.
• Neurological examinations are conducted.
• Symptoms are evaluated.
• Any changes in tumor size are monitored.

Does Every Meningioma Grow?

No.

Studies have shown that some meningiomas may remain unchanged for many years. However, it is not always possible to predict with certainty which tumors will grow.

For this reason, Prof. Dr. Ömür Günaldı highlights the importance of not neglecting regular imaging follow-ups.

Why Doesn't a Meningioma Disappear on Its Own?

Meningiomas are tumors caused by abnormal cell growth.

Because they are not temporary conditions such as infections or edema, they are generally not expected to disappear spontaneously.

Tumor tissue:

• Contains abnormal cells,
• Receives a blood supply,
• Interacts with surrounding tissues.

Therefore, complete spontaneous disappearance through natural processes is considered uncommon.

Can a Meningioma Shrink?

In certain situations, a reduction in meningioma volume may occur.

However, this is relatively uncommon.

Possible factors may include:

• Hormonal changes
• Changes following treatment
• Radiosurgery
• Reduced blood supply to the tumor

Nevertheless, complete disappearance of the tumor should not generally be expected.

What Happens If a Meningioma Is Left Untreated?

The answer depends on the tumor's growth rate, size, location, and other individual factors.

Some patients may experience no significant problems for years, while others may develop symptoms as the tumor grows or affects nearby structures.

Possible symptoms may include:

• Increasing headaches
• Vision problems
• Balance problems
• Seizures
• Memory difficulties
• Neurological deficits

Therefore, whether treatment is necessary should be determined after evaluation by a qualified specialist.

Prof. Dr. Ömür Günaldı states that not every meningioma carries the same level of risk and that treatment plans should be individualized.

What Are the Symptoms of a Meningioma?

The symptoms of a meningioma vary depending on the location and size of the tumor.

Possible symptoms include:

• Persistent headaches
• Nausea and vomiting
• Vision loss
• Double vision
• Balance problems
• Seizures
• Weakness in the arms or legs
• Memory problems
• Difficulty concentrating

Can a Meningioma Progress Without Symptoms?

Yes.

Many patients may experience no symptoms for years. In some cases, a meningioma is discovered incidentally during an MRI scan performed for another reason.

Regular medical evaluation and appropriate follow-up are therefore important.

How Is a Meningioma Monitored?

Monitoring is an important part of meningioma management.

MRI Follow-Ups

Magnetic resonance imaging (MRI) is commonly used to evaluate whether the tumor is growing or changing.

The timing of follow-up MRI scans is determined individually according to factors such as the tumor's characteristics, size, location, previous imaging findings, and the patient's clinical condition.

Neurological Evaluation

The patient's symptoms and neurological condition are regularly evaluated.

Eye Examination

For meningiomas located close to the visual pathways, ophthalmological examinations may also be necessary.

Prof. Dr. Ömür Günaldı notes that regular follow-up can help identify tumors showing significant changes and allow an appropriate treatment plan to be developed when necessary.

Does a Meningioma Require Surgery?

Not every meningioma requires surgery.

Surgery or another form of treatment may be considered in situations involving:

• Significant tumor growth
• Brain edema
• Seizures
• Vision loss
• Neurological problems
• Large tumor size
• Pressure on important brain structures

For some patients, regular monitoring may be the most appropriate approach.

Are There Non-Surgical Treatments for Meningioma?

Yes.

Non-surgical approaches may be considered for appropriately selected patients.

Gamma Knife: A form of stereotactic radiosurgery that uses precisely focused radiation to control tumor growth.

Radiosurgery: This approach may be considered for certain small meningiomas or tumors located in areas where conventional surgery carries additional risks.

Active Monitoring: For some patients, regular observation with imaging and clinical examinations may be the most appropriate strategy.

The choice of treatment depends on factors such as the patient's age and overall health, as well as the tumor's size, location, growth pattern, and other characteristics.

What Should Patients With Meningioma Pay Attention To?

After a meningioma diagnosis, patients should pay attention to several important issues.

Do Not Skip Follow-Up Appointments: MRI scans and medical examinations should be performed according to the follow-up schedule recommended by the treating physician.

Monitor Symptoms: New or worsening neurological symptoms should be reported to a healthcare professional.

Healthy Lifestyle

General healthy lifestyle habits may support overall well-being, including:

• Regular sleep
• A balanced diet
• Avoiding smoking
• Appropriate physical activity

The Importance of Early Diagnosis in Meningioma

Early diagnosis and appropriate evaluation can help doctors monitor the tumor's behavior and determine whether observation or treatment is necessary.

Symptoms such as:

• Severe or persistent headaches
• Vision problems
• Seizures
• Balance problems

should be medically evaluated, particularly when they are new, persistent, or worsening.

Prof. Dr. Ömür Günaldı emphasizes that timely diagnosis and appropriate follow-up can help guide treatment decisions and support the preservation of neurological function and quality of life.

Meningiomas generally do not disappear completely on their own. Some tumors may stop growing or remain stable for many years, while others may gradually increase in size. Spontaneous complete disappearance is uncommon.

For this reason, people diagnosed with meningioma should continue regular MRI monitoring and specialist follow-up. As emphasized by Prof. Dr. Ömür Günaldı, every meningioma has different characteristics, so monitoring and treatment decisions should be individualized for each patient.
