Malignant brain tumors are considered one of the most complex and dangerous medical conditions. Cells grow rapidly inside the brain, which greatly affects the vital functions of the brain. Symptoms vary depending on the size and location of the tumor. It may begin with simple signs such as headaches or disturbances in vision. Later, the symptoms of a malignant brain tumor develop into loss of balance or problems with speech and memory. It is necessary to recognize these symptoms in order to notice them early, as early diagnosis has a role in improving the chances of treatment.

What are the symptoms of a malignant brain tumor?
There are many symptoms of a malignant brain tumor, or what is known as brain cancer, and below we review these symptoms:
- Severe recurrent headaches, most often in the morning, that increase with coughing or sudden changes in intracranial pressure.
- Extreme fatigue and constant drowsiness, which may lead to difficulty waking up or agitation and delirium in the late stages.
- Feeling disturbances in the senses and changes in vision, such as weakness, double vision, or hearing, and loss of the sense of smell or taste, are among the most prominent symptoms of a malignant brain tumor.
- Loss of balance, motor coordination, and walking problems due to tumor pressure on motor pathways.
- The presence of linguistic and cognitive problems such as difficulty speaking, unclear pronunciation, memory loss, changes in personality or mood, and confusion or hallucinations.
- Symptoms of a malignant brain tumor include numbness or weakness in the extremities and drooping on one side of the face, with the appearance of involuntary movements, in addition to tingling or stiffness on one side of the body.
- Unexplained loss of appetite and weight.
- Difficulty swallowing and painful breathing, especially in the late stages.

Types of malignant brain tumor
Malignant brain tumors are divided into many types, differing according to the type of cells from which they arise and their location in the brain. The most prominent of these types are the following:
- Glioma, which is considered one of the most common and dangerous malignant brain tumors, arises from glial cells, and is characterized by its rapid growth and spread into adjacent brain tissue.
- Astrocytomas are classified as malignant tumors when they are third or fourth degree, and they affect the supporting astrocytic cells in the brain.
- Malignant ependymoma, which arises from the cells lining the brain's ventricles, may be particularly malignant in children.
- Medulla tumor, which most often affects children and appears in the cerebellum, is a rapidly growing malignant tumor that can spread to the spinal cord.
- Primary lymphoma of the brain, a rare type of cancer that arises from the lymphocytes of the central nervous system, and most often affects people with weak immune systems.
- High-grade mixed neuroglioma, which has features of astrocytoma and oligodendroglioma, and may be malignant if it is high grade.
- Metastatic tumors do not originate in the brain itself, but rather spread to it from other organs affected by cancer, such as the lung, breast, or skin.

What are the causes of brain tumor?
Research suggests that brain tumors develop when certain genes are damaged and don't work properly, but the reason why these genes are damaged is unknown.
When genes are damaged, brain cells grow faster than normal and live longer. When this happens, they form an abnormal mass or what is known as a brain tumor.
Although the cause of genetic mutations is unknown, they may occur as a result of triggering factors such as:
- the age: The risk of developing a brain tumor increases with age (most brain tumors occur in older people aged 85 to 89 years), however some types of brain tumors are more common in children.
- Radiation: represents Radiation exposure is a risk factor for a number of brain tumors.
- Family history: Certain genetic conditions are known to increase the risk of developing a brain tumor, including neurofibromatosis and Turner syndrome.
What is the difference between a brain tumor and brain cancer?
All brain cancers are tumors, but not all brain tumors are cancerous.
Benign brain tumor
A benign brain tumor grows slowly, has distinct borders, and rarely spreads.
Benign brain tumors located in a vital area of the brain may become life-threatening, and in very rare cases, a benign tumor may turn malignant.
Brain cancer
Symptoms of a malignant brain tumor are cancerous, usually grow quickly and invade healthy brain tissue.
How is a brain tumor detected?
The doctor takes a detailed medical history, conducts a physical examination, and if most other problems associated with the patient's symptoms have been ruled out, he or she will conduct further tests.
Imaging tests help tell whether the tumor is primary (originating in the brain) or metastatic (originating elsewhere in the body and spreading to the brain).
The doctor takes some considerations when choosing the type of examination to diagnose a brain tumor, including:
- Symptoms appearing on the patient.
- The type of suspected tumor.
- The patient's age and general health.
- Results of previous medical examinations.
Brain tumors are generally diagnosed through the following tests:
- Magnetic resonance imaging.
- Taking tissue samples (biopsy), which helps in the final diagnosis of the disease.
How are brain tumors treated?
Choosing the appropriate method to treat brain tumor symptoms depends on several factors, including:
- Tumor type.
- The affected area.
- Tumor size and extent of spread.
- The patient's general health.
The most common treatment for brain tumors is surgery, and surgical resection aims to remove as much of the abnormal tissue as possible.
Medicines to treat brain tumors
The doctor recommends some medications to treat the symptoms of a brain tumor, including:
- Anti-seizure medications.
- Painkillers for headaches.
- مضادات الاكتئاب.
Complications of malignant brain tumor
Symptoms of a brain tumor can lead to many serious complications that affect the patient’s life and physical and mental functions, as a result of the rapid growth of the tumor and its pressure on sensitive parts of the brain. The most prominent complications of a malignant tumor are as follows:
- Loss of neurological functions such as poor movement, partial or complete paralysis, balance disorders, or loss of the ability to speak or understand.
- Convulsions and epilepsy resulting from irritation of brain tissue are common symptoms, and can recur even after treatment.
- Cognitive and psychological disorders such as poor memory, difficulty concentrating, and behavioral changes, in addition to hallucinations or depression.
- Accumulation of cerebrospinal fluid, or what is known as hydrocephalus, occurs due to blockage of the fluid drainage channels, which causes pressure inside the skull, and may require the installation of a shunt to drain it.
- The nerves responsible for sight or hearing are affected as a result of the location of the tumor or treatment.
- Increased intracranial pressure, which leads to severe headache, vomiting, and disturbance of consciousness, and may worsen into coma.
- Even after surgery or radiation therapy, the tumor may reappear or spread to other places in the nervous system.
- Weak immunity, especially as a result of chemotherapy or radiation, increases the risk of infection and weakens the body's ability to resist diseases.
- Complications of the treatment itself, such as damage to surrounding healthy tissue, hair loss, nausea, or digestive problems.
We explain at the end of the article that the symptoms of a brain tumor may be similar to many other conditions, and one should not worry unnecessarily. The condition should also not be neglected, and a doctor should be consulted to find out the cause of the symptoms and its treatment. If the diagnosis indicates the presence of a brain tumor, the majority of cases can be cured as long as they are discovered early and treated immediately after their diagnosis.
Frequently asked questions
How long does a malignant brain tumor patient live?
The length of survival of a patient with a malignant brain tumor depends on the type of tumor, its stage, its location, and the extent of response to treatment. In general, glioblastoma is the most common and dangerous type, and it has the greatest impact on the average life expectancy, as the average survival after diagnosis ranges between 12 months and 18 months, with rare cases living for longer periods with advanced treatments in addition to comprehensive care. The outlook can be better for some other types if they are detected early and treated efficiently, and thanks to advanced treatment methods, the chances of survival have increased.
Does a malignant brain tumor cause blurred vision or double vision?
Symptoms of a brain tumor can cause blurring of the eye or pressure in the vision, especially if the tumor is located in the occipital lobe, which is responsible for processing visual signals, or if the tumor is pressing on the optic nerves. Also, increased pressure inside the skull due to the growth of the tumor leads to swelling of the optic nerve, and thus causes blurred or double vision. These visual symptoms are considered among the most important warning signs that require a quick neurological and ophthalmic examination, especially if they appear suddenly or worsen quickly.
How long does a malignant tumor in the brain last?
The duration of the spread of a malignant tumor in the brain varies according to the type of tumor and the speed of its growth. Some types, such as glioblastoma, are considered very aggressive, and they grow quickly over a period of weeks to a few months, and can spread to neighboring brain tissues without leaving an opportunity for early intervention. However, metastatic tumors that move from other organs to the brain can spread within months, depending on the nature of the cancer. In general, there is no fixed time, but the malignant tumor often develops quickly. Therefore, early diagnosis and early treatment are necessary to reduce the spread of the tumor and improve the chances of survival.
