What is Glioblastoma?

Glioblastoma, also called Glioblastoma Multiforme (GBM), is a Grade 4 brain cancer. It is the most aggressive type of brain tumor because it grows quickly and can spread into nearby brain tissue. Although it usually does not spread to other parts of the body, it can affect important brain functions and requires prompt medical attention.

Glioblastoma can develop in different parts of the brain, but it is most commonly found in the cerebral hemispheres—the largest part of the brain that controls memory, thinking, speech, movement, and vision. The symptoms often depend on the exact location and size of the tumor.

Why Is Glioblastoma a Serious Condition?

• It is a Grade 4 (high-grade) brain cancer.
• It grows and spreads quickly within the brain.
• It can affect important brain functions like speaking, walking, memory, and vision.
• Without treatment, the tumor may continue to grow and cause serious complications.

Why Early Treatment Matters

Early diagnosis and treatment can help control the growth of the tumor, relieve symptoms, and improve quality of life. Depending on the patient's condition, doctors may recommend surgery, radiation therapy, chemotherapy, targeted therapy, or other advanced treatment options. Starting treatment as early as possible also helps doctors create a personalized treatment plan that best suits the patient's needs.

Glioblastoma Symptoms

The symptoms of glioblastoma can be different for each person. They usually depend on the size of the tumor and the part of the brain it affects. Some symptoms may develop slowly, while others can appear suddenly as the tumor grows.

• Persistent headaches: Frequent headaches that become more severe over time or are worse in the morning.
• Seizures (Fits): A seizure may be the first sign of glioblastoma, even in people who have never had one before.
• Memory problems: Difficulty remembering things, confusion, or trouble concentrating on daily activities.
• Vision changes: Blurred vision, double vision, or partial loss of vision caused by pressure on the brain.
• Speech problems: Trouble speaking clearly, finding the right words, or understanding conversations.
• Weakness in the arms or legs: Numbness, weakness, or difficulty walking, depending on which part of the brain is affected.

If you or a loved one experiences these symptoms—especially if they are persistent or getting worse—it is important to consult a doctor as soon as possible. Early diagnosis can help doctors begin the most appropriate treatment without unnecessary delays.

Causes & Risk Factors of Glioblastoma

The exact cause of glioblastoma is still not fully understood. In most patients, doctors cannot identify a single reason why the tumor develops. Glioblastoma usually occurs when genetic changes (mutations) happen in brain cells, causing them to grow and divide uncontrollably. These changes often happen by chance and are not inherited from parents.

Although the exact cause is unknown, researchers have identified several risk factors that may increase the chance of developing glioblastoma. Having one or more of these risk factors does not mean that a person will definitely develop brain cancer, and many people diagnosed with glioblastoma have no known risk factors at all.

Age

Glioblastoma can occur at any age, but it is more common in adults between 45 and 75 years. The risk generally increases as people get older. However, younger adults and, in rare cases, children can also develop this type of brain cancer.

Previous Radiation Exposure

People who have received high-dose radiation therapy to the head or brain for another medical condition may have a slightly higher risk of developing a brain tumor years later. It is important to note that this risk is mainly linked to therapeutic radiation and not to routine diagnostic imaging tests such as X-rays or CT scans.

Rare Genetic Disorders

Most glioblastoma cases are not inherited. However, a small number of patients have rare inherited genetic conditions that increase the risk of brain tumors. These include:

• Li-Fraumeni syndrome
• Neurofibromatosis type 1 (NF1)
• Turcot syndrome
• Lynch syndrome (rarely associated)

These conditions are uncommon and account for only a small percentage of glioblastoma cases.

Most Cases Have No Known Cause

The majority of people diagnosed with glioblastoma have no identifiable cause or family history. Scientists believe that the disease usually develops because of random genetic changes in brain cells rather than lifestyle choices or inherited genes.

Can Glioblastoma Be Prevented?

At present, there is no proven way to prevent glioblastoma. Because the exact cause is unknown, there are no specific lifestyle changes that can completely eliminate the risk. However, maintaining good overall health, attending regular medical check-ups, and seeking medical attention if symptoms such as persistent headaches, seizures, vision changes, or speech problems occur may help with earlier diagnosis and treatment.

Glioblastoma Diagnosis

An accurate diagnosis is the first step in planning the right treatment for glioblastoma. Since the symptoms of glioblastoma can be similar to those of other brain conditions, doctors use a combination of neurological examinations, imaging tests, and laboratory tests to confirm the diagnosis.

Neurological Examination

The doctor begins with a neurological examination to check how well the brain and nervous system are working. This may include testing your memory, vision, hearing, speech, balance, coordination, reflexes, and muscle strength. These tests help identify which part of the brain may be affected by the tumor.

MRI (Magnetic Resonance Imaging)

An MRI scan is the most commonly used imaging test to diagnose glioblastoma. It provides detailed images of the brain, helping doctors determine the size, location, and extent of the tumor. In many cases, a contrast dye is used during the scan to make the tumor easier to see.

CT Scan

A CT scan may be used when an MRI is not available or in emergency situations. It helps doctors quickly identify brain tumors, bleeding, or swelling. However, an MRI usually provides more detailed information for treatment planning.

Biopsy

A biopsy is the most reliable way to confirm a glioblastoma diagnosis. During this procedure, a small sample of the tumor is removed during surgery or with a special needle. A pathologist then examines the tissue under a microscope to determine whether the tumor is cancerous and to confirm that it is glioblastoma.

Molecular Testing

After the biopsy, doctors may perform molecular testing on the tumor tissue. These tests help identify specific genetic changes that can influence treatment decisions and prognosis.

• MGMT Promoter Methylation: Helps predict how well the tumor may respond to chemotherapy, especially temozolomide.
• IDH Mutation Testing: Determines whether the tumor is IDH-mutant or IDH-wildtype, which can affect prognosis and treatment planning.
• Other Biomarker Tests: In some cases, additional genetic or molecular tests may be recommended based on the patient's condition.

Once all test results are available, the medical team reviews the findings and creates a personalized treatment plan based on the tumor's characteristics, location, and the patient's overall health.

Who Can Benefit From Glioblastoma Treatment?

Every patient with glioblastoma has different medical needs. The most suitable treatment depends on the tumor's size, location, previous treatments, and overall health. After reviewing your MRI scans, biopsy reports, and medical history, doctors can recommend the best treatment approach for your condition.

You may benefit from expert evaluation and treatment if you are in any of the following situations:

• Newly Diagnosed Patients
  If you have recently been diagnosed with glioblastoma, early evaluation can help you understand your treatment options and start the most appropriate treatment without unnecessary delays.
