Brain Tumor: Identifying Symptoms, Early Diagnosis & Treatment Options
Center : Neurology Center
Article by : Dr. Chanwit Ankrohwittaya
- Brain tumors are not always cancerous. Benign and malignant tumors both require medical assessment, and both can cause serious neurological symptoms if left untreated.
- The warning signs of a brain tumor include persistent headaches, unexplained seizures, changes in vision, speech difficulties, memory and personality changes, weakness or numbness in the limbs, and balance problems.
- Early symptoms are often vague and overlap with common conditions — the clinical signal is persistence, progression, and the combination of multiple symptoms appearing together.
- Early diagnosis significantly improves treatment outcomes. Diagnosis combines neurological examination, MRI, CT, PET scanning, and biopsy to confirm the tumor type, grade, and extent.
- Brain tumor treatment options include microscopic surgery, endoscopic surgery, radiation therapy (IMRT, IGRT, VMAT), and chemotherapy, often used in combination depending on tumor type and stage.
- Nakornthon Hospital's Brain and Neurology Center offers a complete diagnostic and treatment pathway with a multidisciplinary team covering every stage of brain tumor care.
A brain tumor is a silent danger, often hidden behind chronic headaches, even when the body is well-rested and free from stress or anxiety. Despite feeling physically fine, persistent headaches may still occur. Many people mistake these symptoms for migraines, but they can be signs of something more serious.
Other brain tumor symptoms may appear alongside headaches, such as difficulty speaking, hearing problems, vision issues, and memory disturbances. These signs of a brain tumor in adults often resemble those of a stroke, arteriovenous malformations (AVMs), or cerebral ischemia, making early detection even more critical.
If you experience any warning signs of a brain tumor, it is important to seek medical attention promptly. Delayed diagnosis and treatment can lead to severe complications like paralysis or the progression into brain cancer. Recognizing these early may save your life.
Don't ignore unusual symptoms, whether it's a subtle sign of a brain tumor or sudden neurological changes. If you're concerned, consult with a specialist and learn about brain tumor treatment in Thailand. Online health consultations are also available below for added convenience.

What Is a Brain Tumor?
A brain tumor is a condition caused by the abnormal growth of tissue within the brain or nearby areas, which can affect brain function and the nervous system. This abnormal tissue growth can press against the brain and interfere with essential bodily functions controlled by the brain.
Types of Brain Tumors
Not all brain tumors are cancerous. In fact, tumors found in the brain are categorized into two main types:
- Non-cancerous brain tumors (benign tumors): These occur due to genetic abnormalities or mutations in brain cells that cause the cells to grow and divide at an abnormal rate. These tumors grow slowly, do not contain cancer cells, and can often be completely treated or removed
- Cancerous brain tumors (malignant tumors): These consist of cancer cells that grow rapidly and can spread or press on surrounding brain tissue. They may originate in the brain or spread from other parts of the body. These brain cancer symptoms can progress quickly and significantly impair brain function, posing serious risks to life.
What Causes a Brain Tumor?
Brain tumors can be caused by a variety of factors, and in some cases, the exact cause remains unknown. One common cause is genetic abnormality—mutations in certain genes may lead to abnormal cell growth, eventually forming a tumor. A family history of brain tumors can also increase the risk.
Brain tumor symptoms can occur at any age. However, some types of brain tumors are more common in children, while others appear more frequently in adults and the elderly. If you experience persistent headaches, unexplained seizures, frequent vomiting, or problems with vision or speech, these could be signs of a brain tumor. It's important to see a doctor for a thorough examination, as these could be early brain tumor warning signs. Identifying symptoms of brain tumor early can help doctors identify the right treatment options that lead to better outcomes.
Risk Factors for a Brain Tumor
While the exact cause of a brain tumor is still not fully understood, several factors may increase the risk of developing one. These include:
- Age: A brain tumor can occur at any age, but it is most commonly found in individuals over the age of 40.
- Gender: Statistically, brain tumors occur more frequently in men than in women.
- Exposure to radiation or chemicals: Long-term exposure to ionizing radiation or certain workplace chemicals may raise the risk of developing a tumor, including those that affect the brain.
What Are the Symptoms of a Brain Tumor?
The symptoms of brain tumors vary depending on the tumor’s location, type, and size. Some individuals may not experience any symptoms at all and only discover a tumor incidentally during a health check-up. However, if you experience any of the following brain tumor symptoms, it is important to seek medical attention immediately:
- Persistent headaches is a common early sign. Typically, the headaches occur more than 15 days a month for at least 3 consecutive months.
- Nausea or vomiting, especially vomiting that occurs in the morning without any apparent cause.
- Gradual numbness or loss of movement in the arms or legs, which can sometimes lead to partial paralysis.
- Difficulty with balance or walking.
- Confusion, memory loss, personality changes, or Alzheimer-like behaviors.
- Ringing in the ears (tinnitus) or dizziness.
- Facial muscle numbness or tingling.
- Difficulty swallowing.
- Blurred or double vision.
- Speech difficulties include trouble understanding language or expressing thoughts.
- Loss of bladder or bowel control.
How is a Brain Tumor Diagnosed?
When a patient experiences symptoms that cannot be explained by other conditions or known causes, a doctor may investigate the possibility of a brain tumor by performing brain scans. These imaging techniques provide a detailed view of the brain and surrounding areas. Common methods include CT scan (Computed Tomography), MRI (Magnetic Resonance Imaging), and PET scan (Positron Emission Tomography). These scans help detect the presence of a tumor, identify its size and location, and assess how it may be affecting nearby brain structures.
If a brain tumor is found, further imaging of other organs may be required to determine whether cancer cells have spread from or to other parts of the body.
In addition, a biopsy may be performed to examine a sample of the abnormal tissue. This test helps determine whether the tumor is benign or malignant, as well as its stage and severity. Knowing whether the growth is a non-cancerous tumor or a cancerous mass is essential for creating an accurate and effective treatment plan.
Brain Tumor Treatment Option
Treatment for a brain tumor is personalized based on each patient’s condition. Can a brain tumor be cured? If the tumor is not aggressive and the patient’s condition is stable, the chance of recovery is high, and the need for surgery may be minimal. The main treatment methods for brain tumors include the following:
Brain Surgery
If the tumor is located in a surgically accessible area of the brain that does not endanger surrounding tissues or nerves, doctors may perform surgery to remove as much of the abnormal tissue as possible.
Modern brain surgery techniques include:
- Microscopic surgery involves using a high-powered surgical microscope with precision lighting to reach deep brain areas. This allows surgeons to clearly see and navigate delicate brain structures and nerves, increasing surgical accuracy and reducing injury to nearby vital tissues.
- Endoscopic surgery uses a slender, high-definition camera inserted into the brain through a small incision. This method is particularly suitable for procedures such as relieving brain fluid buildup or removing tumors near the pituitary gland. It offers excellent visibility in deep regions and minimizes trauma to surrounding tissues
Radiation Therapy
This brain tumor treatment option uses high-energy radiation to destroy cancerous cells in the brain tumor while sparing healthy brain tissue. Techniques such as Intensity-Modulated Radiation Therapy (IMRT), Image-Guided Radiation Therapy (IGRT), and Volumetric Modulated Arc Therapy (VMAT) allow for more precise targeting of tumor cells, increasing effectiveness and reducing side effects.
Chemotherapy
Chemotherapy for brain tumors involves using medications to kill or slow the growth of tumor cells. These drugs may be administered orally or through intravenous injection. Depending on the type and severity of the tumor, a combination of drugs may be prescribed. In cases where the brain tumor results from cancer that originated in another organ, treatment will be tailored based on the specific type of cancer involved.

Frequently Asked Questions (FAQs) About Brain Tumor Symptoms
-
Q: Is a brain tumor the same as brain cancer?
A: No, they are not the same, though the two terms are often used interchangeably. A brain tumor is any abnormal growth of cells in the brain, whether benign or malignant. Brain cancer refers specifically to malignant tumors, those made up of cancer cells that grow rapidly and can invade surrounding tissue. A benign brain tumor is not cancer, but it can still cause significant neurological problems if it grows in a location that affects critical brain functions. The distinction matters because it directly affects treatment decisions and prognosis.
-
Q: What is the survival rate for a brain tumor?
A: Survival rates vary enormously depending on the type, grade, and location of the tumor, as well as the patient's age and overall health at the time of diagnosis. Benign brain tumors that are fully resectable carry a very good prognosis, with many patients achieving complete recovery after surgery. For malignant brain tumors, survival rates range widely by tumor type: low-grade gliomas carry a significantly better prognosis than high-grade glioblastomas. Early detection consistently improves outcomes across all tumor types by expanding treatment options and reducing the extent of neurological damage before treatment begins.
-
Q: How fast does a brain tumor grow?
A: Growth rate depends almost entirely on the type and grade of the tumor. Benign tumors, such as meningiomas, often grow very slowly, sometimes over years or even decades, and may cause minimal or no symptoms for extended periods. Malignant tumors, particularly high-grade gliomas such as glioblastoma multiforme (GBM), can grow rapidly, doubling in size within weeks in some cases, and require prompt, aggressive treatment.
-
Q: How common are brain tumors in Thailand?
A: In Thailand, brain tumors are among the neurological conditions treated at private hospitals such as Nakornthon Hospital, though they represent a smaller proportion of overall cancer diagnoses than cancers such as liver, lung, or colorectal cancer. However, rarity does not reduce urgency — brain tumors in any location affect functions essential to daily life and require prompt evaluation when symptoms arise.
-
Q: Can stress cause a brain tumor
A: There is no established scientific evidence that psychological stress directly causes brain tumors. The development of brain tumors is linked to genetic mutations, exposure to ionizing radiation, family history, and immune system factors. That said, some of the symptoms associated with chronic stress, such as persistent headaches, cognitive changes, sleep disruption, overlap with early brain tumor symptoms, which is one reason that persistent or unexplained neurological symptoms should always be evaluated by a doctor.
-
Q: What are the warning signs of a brain tumor?
A: The most recognized warning signs include persistent headaches that do not respond to standard pain relief, new or unexplained seizures, gradual changes in vision, speech difficulties, uncharacteristic memory lapses or personality changes, progressive weakness or numbness in the limbs, balance problems, and unexplained nausea or vomiting, particularly in the mornings. Most of these symptoms have more common explanations. The signal worth acting on is persistence, gradual worsening, or multiple symptoms appearing together without a clear cause. If that describes what you are experiencing, a neurological assessment is the right next step.
