Brain tumours, whether benign or malignant, can significantly affect daily life and overall health. Brain tumour surgery is often a key part of treatment, carried out to remove or reduce the tumour while protecting as much normal brain function as possible. With continued progress in surgical techniques, procedures have become more precise, safe, and less invasive, supporting better outcomes and recovery. As every patient’s condition is unique, the choice of surgery depends on the tumour’s type, size, location, and the individual’s overall health. In this article, we’ll explain what brain tumour surgery involves, the risks, the recovery journey, and long-term care, helping you make informed decisions.
What is Brain Tumour Surgery?
Brain tumour surgery is a procedure performed to remove, reduce, or access a tumour located within the brain or surrounding tissues. The main goal is to take out as much of the tumour as safely possible without damaging healthy areas that control essential functions such as movement, speech, or memory. In many cases, it is the first and most important step in treatment, helping to relieve pressure inside the skull and improve symptoms.
Surgery may also be carried out to obtain a tissue sample for diagnosis, guide further treatment, or insert supportive devices such as shunts to drain excess fluid. The exact approach depends on the tumour’s size, location, and type, as well as the patient’s overall health. Modern surgical techniques, including image guidance and minimally invasive methods, help improve precision and recovery outcomes.
When Surgery is Recommended
Surgery may be advised when several key factors indicate that an operation will help manage the tumour effectively. These include:
- Tumour size: When the tumour is large or causing pressure inside the skull.
- Tumour location: When the tumour is in an area that can be safely accessed by surgeons.
- Patient health: When the patient is medically fit to undergo a brain tumour operation.
- Symptoms: When symptoms such as headaches, seizures, or vision changes are significant or worsening.
Causes and Risk Factors
The exact cause of many brain tumours is not fully understood, but several factors may increase the likelihood of developing one. These include:
- Genetic predisposition: Inherited conditions and specific gene mutations linked to tumour development.
- Environmental exposures: Long-term exposure to ionising radiation, including previous head radiotherapy.
- Lifestyle and medical conditions: Weakened immunity and some long-standing health issues that may contribute to tumour growth.
Note: While having one or more risk factors does not mean a person will develop a brain tumour, being aware of them can help support early detection and timely medical evaluation.
Symptoms of Brain Tumours
Brain tumour symptoms vary based on the tumour’s size, location, and growth rate. Common signs include:
- Headaches and nausea: Persistent morning headaches with nausea or vomiting due to raised pressure in the skull.
- Seizures: Sudden seizure episodes or unusual jerking movements caused by abnormal brain activity.
- Vision, speech, or balance problems: Blurred vision, speech difficulties, or coordination issues linked to affected brain regions.
- Cognitive or behavioural changes: Memory lapses, confusion, personality changes, or reduced concentration.
Diagnosis and Pre-Surgical Evaluation
Accurate diagnosis is essential for planning a safe and effective brain tumour operation. Doctors use a combination of imaging tests, neurological assessments, and tissue sampling to understand the tumour’s characteristics and decide the most appropriate surgical approach.
Imaging Tests
- MRI scan: The primary imaging tool for brain tumours, offering detailed views of the brain’s structures and helping identify the tumour’s size, location, and impact on surrounding tissues.
- CT scan: Used when an MRI is not suitable or to detect bleeding, swelling, or bone involvement. It provides quick and useful information during emergency situations.
Biopsy and Pathology
A biopsy may be performed when the tumour’s type cannot be confirmed through imaging alone. During this procedure, a small tissue sample is taken and analysed under a microscope. Biopsy results help determine whether the tumour is benign or malignant and guide further treatment planning.
Preoperative Health Assessments
Before surgery, patients undergo a series of evaluations to ensure they are fit for the procedure. These may include:
- Blood tests to assess overall health
- Neurological examinations to document baseline function
- Anaesthetic reviews to plan safe sedation
- Additional tests such as ECG or chest X-ray depending on individual needs
Thorough pre-surgical evaluation helps reduce risks, supports decision-making, and prepares patients for the upcoming operation.
Surgical Options Available for Brain Tumour Care
Different brain tumour operations are performed based on the tumour’s size, type, and location, as well as the safest route for removal or diagnosis. These procedures aim to reduce tumour burden, relieve pressure on the brain, or obtain tissue for further evaluation. Common types of brain tumour surgery include:
Craniotomy
A craniotomy is the most common brain tumour operation. Surgeons temporarily remove a small section of the skull to reach the tumour directly. It is preferred for tumours that are accessible and large enough to require open removal.
Benefits
- Allows precise access to the tumour
- Enables removal of larger or deeper growths
- Offers good surgical visibility and control
Endonasal Endoscopic Surgery
This minimally invasive technique accesses certain tumours through the nose and sinuses using an endoscope equipped with a camera and light. Often used for tumours near the base of the skull, such as pituitary tumours.
Benefits
- No external incisions
- Faster recovery
- Reduced disruption of surrounding brain tissue
Neuroendoscopic Surgery
A keyhole procedure using tiny openings and specialised endoscopes to reach deeper parts of the brain. Suitable for select tumours within the ventricles or areas where a narrow pathway can be safely used.
Benefits
- Less invasive than open surgery
- Shorter hospital stay
- Lower risk of tissue disturbance
Biopsy Procedures
A biopsy involves removing a small sample of tumour tissue for laboratory analysis. When the tumour cannot be fully removed safely or when diagnosis is uncertain.
Benefits
- Helps determine whether the tumour is benign or malignant
- Guides treatment decisions such as radiotherapy or chemotherapy
Shunt Surgery
A shunt is placed to drain excess cerebrospinal fluid when a tumour blocks normal fluid flow, causing hydrocephalus. Recommended when the tumour leads to increased pressure in the brain.
Benefits
- Relieves symptoms like headaches and nausea
- Helps stabilise patients before or after tumour surgery
Risks and Potential Complications
Brain tumour operation is generally safe when performed at a well-equipped centre, however like any major procedure it carries certain risks. These may include:
- Bleeding: Small blood vessels in the brain may bleed during or after surgery.
- Infection: There is a minor risk of wound or brain infection, usually managed with antibiotics.
- Swelling of the brain: Temporary swelling may cause headaches, nausea, or neurological symptoms.
- Neurological changes: Depending on the tumour’s location, patients may experience weakness, speech difficulties, or coordination issues.
- Seizures: Some individuals may develop seizures post-surgery, often controlled with medication.
- Reactions to anaesthesia: Like any surgical procedure, there is a small risk of anaesthetic-related complications.
Recovery and Lifestyle After Surgery
Recovery from a brain tumour operation is a gradual process focused on healing, regaining strength, and adapting to any changes in daily functioning. With the right post-operative care and appropriate lifestyle adjustments, the journey becomes smooth and manageable for patients and their families.
- Hospital stay and early care: Patients spend a few days in hospital for neurological monitoring, symptom checks, and medication management to support safe recovery.
- Rehabilitation and therapy: Therapies such as physical, occupational, and speech or cognitive rehabilitation help patients regain strength, independence, and mental function.
- Gradual return to daily activities: Routine tasks are resumed slowly based on medical advice, with adequate rest to manage fatigue.
- Diet, exercise, and lifestyle: A balanced diet, light doctor-approved exercise, and healthy habits support healing and long-term wellbeing.
- Emotional support and caregiver role: Counselling, support networks, and caregiver involvement play a key role in helping patients cope emotionally and manage daily needs after surgery.
Choosing the Right Hospital and Surgical Team
Selecting the right centre for a brain tumour operation can significantly influence treatment outcomes, recovery, and long-term wellbeing. A well-equipped hospital and an experienced neurosurgical team ensure safe procedures, accurate diagnosis, and comprehensive care throughout the patient journey.
