9 Warning Signs & Symptoms Of Brain Tumor

Brain tumors arise when abnormal growths develop within the brain tissue. These tumors can be non-cancerous or cancerous and can originate from brain cells or spread from other parts of the body.

While the exact causes remain unclear, certain risk factors like genetic predisposition, radiation exposure, and compromised immune systems have been associated with their development.

Benign brain tumors, though not cancerous, can still cause significant health issues by pressing on surrounding brain structures, leading to an array of symptoms.

On the other hand, cancerous brain tumors are life-threatening and can infiltrate healthy brain tissue, rapidly affecting essential brain functions.

Signs & Symptoms Of Brain Tumor

Recognizing the signs and symptoms of a brain tumor is crucial for early detection and timely intervention.

While these warning signs may not always indicate a tumor, it is essential to pay attention to any changes in your health and seek medical attention if you notice anything unusual.

In this article, we will shed light on some of the common signs and symptoms of brain tumors, aiming to raise awareness and empower you to take charge of your health.

1. Frequent and never-ending headaches

While headaches are common and often caused by various factors, they can also serve as a potential warning sign of a brain tumor.

A brain tumor can put pressure on sensitive brain tissues. This pressure may cause headaches, which can differ from typical headaches.

These headaches may persist over time, becoming more severe and resistant to usual headache remedies like rest or painkillers.

Additionally, the American Brain Tumor Association reported that headaches caused by brain tumors are often characterized by specific features.

These features may include headaches that worsen in intensity over time, occur during the night or early morning, and are accompanied by other neurological symptoms like seizures (1), vision problems, or cognitive difficulties.

It is important to note that not all headaches indicate a brain tumor, as headaches can stem from stress, tension, migraines, or sinus problems (2).

However, when headaches are accompanied by other concerning symptoms it’s crucial to seek medical attention promptly.

2. Speech and vision problems

When a brain tumor develops, it can affect the parts of the brain responsible for speech and vision.

As a result, individuals may experience difficulties in expressing themselves clearly or understanding others.

They might stammer, slur their words, or have trouble finding the right words to say.

In some cases, language comprehension can also be impaired, making it challenging to follow conversations or written text.

Vision problems (3) related to brain tumors can also vary depending on the tumor’s location.

Some people may notice blurriness, double vision, or a loss of peripheral vision.

Others might have trouble with eye coordination, making it hard to focus on objects or judge distances accurately.

It’s essential to remember that speech and vision issues alone do not definitively mean a brain tumor is present.

Various other factors, such as migraines, strokes, or infections, can also cause similar symptoms.

3. Focal deficit

A focal deficit (4) refers to a specific weakness or problem that occurs in a particular area of the body, indicating damage or dysfunction in the corresponding region of the brain.

One of the possible causes of a focal deficit is a brain tumor.

While not all focal deficits are necessarily linked to brain tumors, recognizing these signs is crucial for early detection and timely medical intervention.

Focal deficits can manifest in various ways, depending on the affected brain area.

For instance, weakness or paralysis in specific limbs, difficulty speaking, impaired vision, loss of coordination, and altered sensation may occur.

These symptoms often persist and may worsen gradually.

If you experience any of these focal deficits, it is crucial to seek medical attention promptly.

Early diagnosis and treatment are vital to improve the chances of successful tumor management.

4. Feeling sick

Feeling sick is a common and often vague symptom that can be caused by various factors, including infections, stress, or fatigue.

However, in rare cases, persistent and unexplained feelings of sickness could be an indication of an underlying health issue, such as a brain tumor.

Research studies have revealed that certain brain tumors can elicit symptoms that may be confused with general sickness.

These tumors can put pressure on different parts of the brain, affecting vital functions and causing diverse symptoms.

Some of the common symptoms associated with brain tumors include nausea, vomiting and difficulties with balance or coordination.

It’s crucial to emphasize that feeling sick alone is not a definitive sign of a brain tumor.

In most instances, feeling sick is not related to such serious conditions.

However, when accompanied by other persistent and unexplained neurological symptoms, it becomes essential to seek medical attention as soon as possible.

5. Muscle weakness

Muscle weakness can be a crucial warning sign that something might be wrong within the intricate workings of our brains.

This weakness may occur because the tumor can put pressure on or infiltrate areas of the brain responsible for controlling muscle movements.

As a result, signals from the brain to the muscles may get disrupted or slowed down, leading to weakness or difficulty in moving certain body parts.

If you experience unexplained muscle weakness, it is essential to pay attention to other accompanying symptoms.

These additional symptoms may provide further clues pointing toward a potential brain tumor.

6. Sleeping issues

Sleep is an essential aspect of our lives, promoting physical and mental well-being.

However, when experiencing persistent and unexplained sleeping issues, it could be a cause for concern.

While there are various reasons for sleep disturbances, one possible but rare explanation is the presence of a brain tumor.

The reason behind the link between brain tumors and sleeping issues lies in their impact on the brain’s delicate structures.

Tumors can press on certain areas of the brain, leading to disturbances in the sleep-wake cycle, causing insomnia or excessive sleepiness.

Moreover, these tumors may also disrupt the production of essential sleep-regulating chemicals, further complicating sleep patterns.

7. Changes in personality

Personality changes can sometimes be indicative of underlying health issues, including brain tumors.

The brain is a complex organ that controls our thoughts, emotions, and behaviors.

Therefore, any abnormalities in its structure or function can lead to significant alterations in personality. Numerous studies have investigated the relationship between brain tumors and personality changes.

One such study published in the Journal of Neurology found that patients with brain tumors exhibited notable shifts in their personalities.

They displayed heightened irritability, mood swings, and social withdrawal, which were not present before the tumor’s development.

Another study in the Journal of Neuro-Oncology reported that certain brain tumor types, such as those in the frontal lobe (5) or limbic system (6), were more likely to cause personality alterations due to their proximity to regions that regulate emotions and behavior.

8. Numbness

Numbness is a condition where a person experiences a lack of sensation or a tingling feeling in a specific part of their body.

While numbness can often be caused by harmless factors like sitting in one position for too long, it can sometimes indicate underlying health issues, including brain tumors.

Researchers have discovered that the tumors can compress the brain’s sensory pathways, interfering with the transmission of signals responsible for sensing touch and temperature.

One study found that nearly 20% of brain tumor patients experienced numbness as one of their initial symptoms.

9. Seizures

A seizure is like an electrical storm in the brain, causing sudden changes in behavior, movements, and consciousness.

During a seizure, a person may experience convulsions, shaking, or a loss of control over their body.

When a brain tumor develops, it can interfere with the brain’s normal activities, disturbing the electrical signals that keep everything running smoothly. These disruptions can trigger seizures.

While seizures can be alarming, it’s essential not to jump to conclusions about having a brain tumor.

Many seizures have different reasons, such as genetics, head injuries, infections, or problems with brain development.

How to get rid of brain tumors?

The diagnosis of brain tumors involves a thorough examination of the patient’s medical history, neurological assessments, and various imaging techniques, such as MRI and CT scans (7).

Early detection is crucial for effective treatment and improved outcomes. The treatment of brain tumors largely depends on their type, size, and location.


Surgery is one of the primary treatment options for brain tumors, especially when the tumor is accessible and can be safely removed.

During the procedure, a skilled neurosurgeon carefully removes as much of the tumor as possible without causing damage to healthy brain tissue.

Surgical resection aims to reduce the size of the tumor, alleviate symptoms, and improve the patient’s quality of life.

Radiation therapy

Radiation therapy is another essential treatment for brain tumors. It uses energy rays to target and destroy cancer cells. Radiation can be executed internally or externally.

External beam radiation involves directing radiation from outside the body precisely at the tumor, while internal brachytherapy (8) involves placing a radiation source directly inside or near the tumor.


Chemotherapy involves the use of powerful medication to kill rapidly dividing cells, including cancer cells.

It may be particularly useful for tumors that are difficult to reach surgically or those that have spread to other parts of the brain.

Research into brain tumors is ongoing, with scientists continuously striving to uncover better treatment options and potential preventive measures.


Brain tumors are serious and complex health conditions that can affect anyone, regardless of age or background.

It is clear that early detection (9) is crucial for a better prognosis, as some tumors can grow silently without causing noticeable symptoms until they become more advanced.
