How Likely Am I to Survive a Brain Tumor?

Reviewed by Preston Robert Tisch Brain Tumor Center Specialists | Last updated: September 2026

A brain tumor diagnosis does not come with one survival rate. How likely someone is to survive a brain tumor depends on the tumor type, grade, molecular characteristics, location, age, overall health, treatment options, and how the tumor responds to treatment. Some brain tumors are slow-growing and can be managed for many years, while others are more aggressive and require intensive treatment.

Survival statistics can provide useful context, but they cannot predict exactly what will happen to one person. The most meaningful prognosis comes from combining population-level statistics with the specific characteristics of an individual's tumor and response to treatment.

Key Takeaways: How Likely Am I to Survive a Brain Tumor?

There is no single survival rate for all brain tumors because brain tumors include many different diseases with very different behaviors.
The latest U.S. SEER data show a 32.9% five-year relative survival rate for brain and other nervous system cancers, based on people diagnosed from 2016–2022. This statistic includes multiple tumor types and does not represent the prognosis for an individual patient.
Tumor type, grade, molecular characteristics, location, age, overall health, extent of tumor removal, and response to treatment can all influence prognosis.
Molecular testing has become increasingly important because markers such as IDH mutations, 1p/19q codeletion, and MGMT promoter methylation can provide diagnostic, prognostic, or treatment-related information for certain tumors.
Treatment continues to evolve, including more personalized therapies and clinical trials evaluating new approaches for brain tumors.

What Is the Survival Rate for a Brain Tumor?

The most important thing to understand is that “brain tumor survival rate” is not one number. Brain tumors can be benign or malignant, and even malignant brain tumors can differ substantially in their biology and expected behavior.

For people diagnosed with brain and other nervous system cancers in the United States, the current five-year relative survival rate is 32.9%, according to the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. The figure is based on SEER 21 data for people diagnosed from 2016 through 2022.

However, this number should not be interpreted as an individual's probability of surviving five years. SEER explains that relative survival is a population-level measure that estimates survival from the cancer compared with people without the cancer, while accounting for other causes of death. Because these statistics combine many different tumors and patients, they cannot predict an individual outcome.

It is also important to distinguish brain tumors from brain cancer. Some brain tumors are noncancerous, or benign, and may be monitored rather than treated immediately. Others are malignant and may require surgery, radiation therapy, chemotherapy, targeted treatment, or combinations of these approaches.

That distinction is one reason a general internet search for a “brain tumor survival rate” can be difficult to interpret without knowing the diagnosis.

Brain Tumor Survival Rates Vary by Tumor Type

A diagnosis becomes much more informative once the specific tumor type is known.

For example, a low-grade glioma and glioblastoma are both brain tumors, but they have substantially different biological characteristics and treatment considerations. Meningiomas, schwannomas, gliomas, embryonal tumors, and other tumors also have different expected courses.

This is why a doctor generally does not estimate prognosis from the words “brain tumor” alone. The pathology and, increasingly, molecular findings help determine what type of tumor is present and how it is expected to behave.

Benign and Slow-Growing Tumors

Some tumors grow slowly and may not behave like malignant cancers. Depending on the tumor type, size, location, symptoms, and whether it can be safely removed, treatment may involve observation, surgery, radiation therapy, or another approach.

For these tumors, survival may be substantially different from statistics reported for aggressive malignant brain cancers. Learn more about benign tumors in our Benign Brain Tumors Explained article.

Gliomas

Gliomas are a broad group of tumors arising from glial cells. Their behavior varies considerably according to their specific diagnosis and molecular characteristics.

Modern classification increasingly incorporates molecular information rather than relying only on what tumor cells look like under a microscope. For certain diffuse gliomas, alterations involving IDH1 or IDH2 and 1p/19q codeletion provide important diagnostic and prognostic information.

Glioblastoma

Glioblastoma is an aggressive primary brain tumor. Because its prognosis differs substantially from that of many other brain tumors, glioblastoma-specific statistics should not be substituted for a general brain tumor survival rate.

Treatment for newly diagnosed glioblastoma may include surgery followed by radiation therapy and chemotherapy, with temozolomide commonly incorporated into treatment. Tumor characteristics such as MGMT promoter methylation can also provide prognostic information and may help inform expectations about response to temozolomide.

For someone newly diagnosed with glioblastoma, therefore, asking “What is the survival rate for a brain tumor?” may provide less useful information than asking the treating team:

“What does my tumor's pathology and molecular profile tell us about its expected behavior and treatment options?”

What Factors Affect Brain Tumor Survival?

Doctors consider several pieces of information when estimating prognosis. These factors are evaluated together rather than in isolation.

1. Tumor Type

The diagnosis is one of the most important starting points.

Different tumor types grow at different rates, respond differently to treatment, and have different patterns of recurrence. A survival statistic for one tumor should not automatically be applied to another.

2. Tumor Grade

Tumor grade describes characteristics associated with how aggressively a tumor behaves.

Lower-grade tumors often grow more slowly, although “low grade” does not necessarily mean harmless or that treatment will never be needed. Higher-grade tumors generally have more aggressive biological behavior.

Importantly, tumor classification has become more sophisticated. Molecular findings can change or refine the diagnosis and may provide additional information about expected behavior.

3. Molecular Characteristics

Modern brain tumor care increasingly incorporates molecular testing.

For example, IDH1 and IDH2 alterations are important in the classification and prognosis of certain gliomas. 1p/19q codeletion is characteristic of oligodendroglioma and is an important prognostic marker. In glioblastoma, MGMT promoter methylation is associated with improved survival and can provide information about the likelihood of benefit from temozolomide.

This means two tumors that appear similar under a microscope may not have identical prognoses once their molecular characteristics are understood.

4. Tumor Location

Where a tumor develops can affect both symptoms and treatment options.

A tumor located near areas responsible for speech, movement, vision, memory, or other critical functions may be more difficult to remove completely without affecting healthy brain tissue. The NCI identifies tumor location and the ability to achieve a gross total resection among factors that can influence prognosis for certain central nervous system tumors.

5. Extent of Tumor Removal

For tumors that can be treated surgically, the amount of tumor that can be safely removed may affect subsequent treatment and prognosis.

However, more surgery is not automatically better in every situation. The goal is to balance tumor removal with preservation of neurological function. A tumor's location may make complete removal unsafe, and treatment plans can incorporate radiation, chemotherapy, or other therapies when residual tumor remains.

6. Age and Overall Health

Age and overall health can influence prognosis and the ability to tolerate intensive treatment.

For an individual patient, clinicians consider more than chronological age. Functional status, other health conditions, neurological function, and the person's ability to undergo particular treatments can all be relevant.

7. Response to Treatment

Initial pathology and molecular testing help establish a starting point, but the tumor's response over time also matters.

Follow-up MRI scans and clinical assessments help the medical team determine whether treatment is controlling the tumor, whether additional treatment is needed, and whether an imaging change represents treatment effect or tumor progression.

8. Recurrence

Some brain tumors can return after treatment. Recurrence does not necessarily mean there are no further treatment options, but it can change the goals and available approaches.

Depending on the tumor type and prior treatment, management of recurrent disease may include surgery, radiation, systemic therapies, targeted therapies, or a clinical trial.

How Are Brain Tumor Survival Statistics Calculated?

Understanding the terminology behind survival statistics can make these numbers easier to interpret.

What Is Five-Year Relative Survival?

A five-year relative survival rate estimates how many people with a particular cancer are alive five years after diagnosis compared with people in the general population who are similar in characteristics such as age, sex, and race.

For example, a five-year relative survival rate of 33% does not mean that a person has only five years to live. Some people live considerably longer, and this should be considered as a population statistic, not a countdown clock.

Why Can the Numbers Change Over Time?

Survival statistics are updated as new data become available. They also reflect people who were diagnosed during earlier periods, meaning they may not capture every benefit of treatments introduced more recently.

This is one reason it is important to avoid interpreting an older survival statistic as though it describes every patient receiving treatment today.

How Have Brain Tumor Treatments Advanced?

Treatment for brain tumors has become increasingly individualized.

Depending on the tumor, modern care may involve several approaches working together:

Surgery and More Precise Tumor Removal

Surgery can provide tissue needed for diagnosis and, when appropriate, remove as much tumor as can be safely removed.

Advances in imaging, surgical planning, and intraoperative techniques continue to support efforts to distinguish tumor from healthy brain tissue and preserve neurological function.

Radiation Therapy

Radiation therapy can be used after surgery, instead of surgery in selected circumstances, or when a tumor returns.

Techniques designed to deliver radiation more precisely can help clinicians target tumor tissue while limiting exposure to surrounding structures.

Chemotherapy

Chemotherapy remains an important part of treatment for several types of brain tumors.

For newly diagnosed glioblastoma, for example, the NCI describes surgery followed by radiation therapy with concurrent and subsequent temozolomide as a standard treatment approach.

Molecularly Guided and Targeted Treatment

One of the most significant developments in brain tumor care is the growing role of molecular classification.

The NCI reports that targeted treatments are being developed around specific molecular changes driving tumor growth. One example is vorasidenib, which the FDA approved in 2024 for certain people with IDH-mutant grade 2 astrocytoma or oligodendroglioma following surgery. In a large clinical trial, the treatment delayed tumor growth and the need for additional therapies in appropriately selected patients.

This illustrates why the question of prognosis increasingly involves more than tumor appearance or location. The molecular profile can help identify which treatments may be relevant.

Clinical Trials

Clinical trials are another important part of advancing brain tumor treatment.

Trials may investigate new drugs, combinations of existing therapies, surgical techniques, imaging approaches, or other treatment strategies. For some patients, discussing clinical trial eligibility early in treatment can be an important part of understanding the available options.

What Can a Doctor Tell You About Your Prognosis?

A population survival statistic is only one piece of a prognosis discussion.

If you or a loved one has received a brain tumor diagnosis, ask the medical team questions such as:

What specific type of brain tumor is it?
What grade is the tumor?
What molecular or genetic findings were identified?
Where is the tumor located?
Can the tumor be safely removed, and how much can be removed?
What treatment is recommended, and what is its goal?
How does the tumor's molecular profile affect treatment options?
What will the follow-up schedule look like?
How will we know whether treatment is working?
Are there clinical trials that may be appropriate?

These questions move the conversation from a broad statistic toward the factors that are actually relevant to an individual diagnosis.

What Does a Brain Tumor Diagnosis Mean for the Future?

A brain tumor diagnosis does not determine a person's future from the diagnosis alone.

The prognosis becomes clearer as doctors establish the exact tumor type, grade, molecular characteristics, location, extent of disease, and response to treatment. In some cases, the initial diagnosis may be refined after surgery and molecular testing.

It is also important to remember that survival and quality of life are related but different outcomes. Treatment planning may consider tumor control alongside neurological function, symptom management, independence, and the patient's goals.

For these reasons, a personalized prognosis is more meaningful than applying a single survival percentage to everyone with a brain tumor.

Understanding Your Brain Tumor Prognosis

If you have been diagnosed with a brain tumor, survival statistics can provide context, but they should be viewed as a starting point rather than a prediction.

The most useful prognosis discussion considers the specific tumor diagnosis, grade, molecular profile, location, extent of removal, treatment plan, and response to therapy. As brain tumor research advances, molecular testing and increasingly personalized treatment approaches are becoming an important part of these conversations.

FAQs: How Likely Am I to Survive a Brain Tumor?

How long can someone live with a brain tumor?

There is no single life expectancy for someone with a brain tumor because prognosis varies substantially by tumor type, grade, molecular characteristics, location, age, and treatment response. Some tumors can be controlled for many years, while aggressive tumors may progress more quickly. A neuro-oncology team can provide a more individualized estimate after reviewing the pathology, imaging, molecular testing, and treatment response.

Does age affect brain tumor survival?

Age can be one factor associated with prognosis, but it should not be considered by itself. Doctors also consider the tumor's biology, molecular characteristics, location, neurological function, overall health, and available treatment options.

Can a brain tumor be completely cured?

Some brain tumors can be successfully removed or controlled for long periods, but whether a tumor can be cured depends on its specific type and biological behavior. A tumor's location can also affect whether complete surgical removal is possible without causing significant neurological injury. For some malignant brain tumors, treatment focuses on controlling the disease, extending survival, preserving neurological function, and maintaining quality of life.

Does a brain tumor always come back?

No. Recurrence depends on the tumor type, grade, molecular characteristics, extent of treatment, and other factors. Some tumors have a relatively low risk of recurrence after appropriate treatment, while others are more likely to return and require long-term monitoring. Follow-up imaging and clinical evaluations allow the care team to look for changes over time.
