Brain Tumor Surgery: Understanding Symptoms, Causes and Treatment Options

A brain tumor is an abnormal growth of cells in or around the brain. Depending on its type, location, and growth rate, it may affect important functions such as movement, speech, memory, vision, and coordination. Some brain tumors grow slowly and may not cause noticeable problems initially, while others can progress more quickly and require timely medical attention.

Brain tumor surgery is an important treatment option for many patients. It may help remove the tumor, reduce pressure on surrounding brain tissue, and provide a sample for detailed examination. Understanding the possible causes, recognizing warning signs, and knowing when surgery may be necessary can help patients make informed decisions about their care.

What Is Brain Tumor Surgery?

Brain tumor surgery is a neurosurgical procedure performed to remove all or part of an abnormal growth in the brain. The main aim is to remove as much of the tumor as safely possible while protecting the healthy areas responsible for essential body functions.

Surgery may also be performed to collect a tissue sample, reduce pressure inside the skull, or help determine the exact type of tumor.

Not every brain tumor requires immediate surgery. The treatment approach depends on the tumor's size, location, type, grade, growth pattern, and the patient's overall health.

What Are the Causes of Brain Tumors?

The exact brain tumor causes are not known in most cases. Brain tumors develop when abnormal cells grow and multiply in an uncontrolled manner.

However, certain factors may increase the risk of developing particular types of brain tumors.

1. Genetic Conditions

Some inherited genetic conditions, including neurofibromatosis and von Hippel-Lindau disease, can increase the risk of certain brain and nervous system tumors.

2. Exposure to Radiation

Exposure to ionizing radiation, particularly previous radiation treatment involving the head, is a recognized risk factor for certain types of brain tumors.

3. Age

Brain tumors can occur at any age. However, the likelihood of developing certain types increases with age, while some tumor types are more common in children and younger individuals.

4. Family History

Having a close relative with a brain tumor may be relevant in certain cases, although most brain tumors are not directly inherited.

It is important to understand that many people who develop brain tumors have no identifiable risk factors. Having a risk factor does not necessarily mean that a person will develop a tumor.

What Are the Common Brain Tumor Symptoms?

Recognizing brain tumor symptoms is important because early medical evaluation can help identify the underlying condition.

Symptoms vary depending on the tumor's location, size, and growth rate. Common warning signs include:

• Persistent headaches: Headaches that are new, increasingly frequent, or progressively worsening.

• Seizures: New or unexplained seizures can sometimes be an early sign of a brain tumor.

• Nausea and vomiting: These may occur when a tumor causes increased pressure inside the skull.

• Vision problems: Blurred vision, double vision, or changes in peripheral vision.

• Speech difficulties: Trouble speaking, understanding language, or finding the right words.

• Weakness or numbness: Reduced strength or sensation in an arm, leg, or one side of the body.

• Memory and personality changes: Difficulty concentrating, confusion, or unusual behavioural changes.

• Balance problems: Difficulty walking, maintaining coordination, or performing everyday movements.

These symptoms can also occur due to other medical conditions. Their presence does not automatically indicate a brain tumor, but persistent or worsening symptoms should be evaluated by a medical professional.

How Are Brain Tumors Diagnosed?

Accurate diagnosis is important before deciding on a treatment plan. Doctors usually begin with a medical history and neurological examination to assess vision, hearing, balance, coordination, reflexes, and muscle strength.

Depending on the findings, additional investigations may include:

MRI Scan: Magnetic resonance imaging provides detailed images of the brain and helps identify the tumor's location, size, and characteristics.

CT Scan: A computed tomography scan may be used to identify abnormalities, particularly when a quick assessment is required.

Biopsy: In selected cases, a tissue sample is examined under a microscope to determine the tumor type and grade. A biopsy may sometimes be performed during surgery.

The results help the medical team understand the nature of the tumor and plan appropriate treatment.

When Is Brain Tumor Surgery Required?

Surgery may be recommended when a tumor is causing symptoms, putting pressure on surrounding brain tissue, or needs to be removed or sampled for further examination.

Some situations in which surgery may be considered include:

• A tumor that is accessible and can be safely removed.

• Increasing pressure on nearby brain structures.

• Symptoms such as seizures, weakness, or neurological difficulties associated with the tumor.

• The need to obtain tissue for an accurate diagnosis.

• Tumor growth or changes observed during follow-up scans.

However, surgery is not suitable for every patient. Some slow-growing tumors may be monitored, while others may be treated with radiation therapy, chemotherapy, targeted medicines, or a combination of approaches.

What Happens During Brain Tumor Surgery?

The surgical approach depends on the tumor's location, size, and type.

One commonly performed procedure is a craniotomy. During this operation, the surgeon temporarily removes a section of the skull to access the tumor. The abnormal tissue is then removed as safely as possible, and the bone section is placed back.

In selected cases, minimally invasive or endoscopic techniques may be considered. Advanced surgical planning and monitoring techniques may also help protect important brain functions.

The objective is not always to remove every part of the tumor. When a tumor is close to critical structures, removing it completely may create unnecessary risks. The surgeon therefore balances tumor removal with the protection of healthy brain tissue.

Recovery After Brain Tumor Surgery

Recovery depends on the type of tumor, the extent of surgery, the patient's overall health, and whether additional treatment is required.

After surgery, patients are monitored in the hospital for neurological changes and other possible complications. Some patients may experience temporary headaches, tiredness, or difficulty with movement and concentration.

Rehabilitation may include physiotherapy, occupational therapy, or speech therapy, depending on the patient's needs.

Regular follow-up appointments and brain imaging are important for monitoring recovery and checking for any changes in the treated area.

Conclusion

Brain tumors can affect different brain functions depending on their size, location, and type. Although their exact causes are often unknown, recognizing persistent or unusual neurological symptoms can help patients seek timely medical evaluation.

Brain tumor surgery may be recommended to remove abnormal tissue, reduce pressure on the brain, or obtain a sample for examination. The most suitable treatment depends on the individual diagnosis and overall health of the patient.

Consulting an experienced neurosurgeon can help patients understand their treatment options and make informed decisions about their care.
