Brain Tumor Surgery doctors in India

What is Brain Tumor Surgery?

Brain tumor surgery is a neurosurgical procedure performed to remove abnormal growths (tumors) from the brain. Brain tumors can be benign (non-cancerous) or malignant (cancerous) and may affect brain function depending on their size and location.

The primary goal of brain tumor surgery is to remove as much of the tumor as possible while preserving healthy brain tissue and neurological function. In many cases, surgery is the first and most important step in treating brain tumors, followed by treatments such as radiation therapy or chemotherapy if necessary.

Modern neurosurgical techniques allow surgeons to perform this procedure with high precision using advanced imaging systems, microscopes, and minimally invasive tools.

Why Brain Tumor Surgery is Performed

Doctors may recommend brain tumor surgery for several reasons, including:

● Removing the tumor completely when possible

● Reducing tumor size to relieve pressure on the brain

● Obtaining a biopsy sample for diagnosis

● Improving neurological symptoms such as headaches, seizures, or vision problems

● Enhancing the effectiveness of other treatments like radiation or chemotherapy

Surgery can also improve a patient’s quality of life by relieving pressure inside the skull caused by the tumor.

Types of Brain Tumor Surgery

Depending on the tumor’s location, size, and type, doctors may perform different surgical approaches:

1. Craniotomy

This is the most common type of brain tumor surgery. The surgeon temporarily removes a portion of the skull to access and remove the tumor.

2. Awake Brain Surgery

Also called awake craniotomy, this procedure is performed while the patient is awake but sedated. The surgeon asks the patient questions or performs tasks to monitor brain functions like speech and movement during surgery.

3. Endoscopic Brain Surgery

A minimally invasive technique where surgeons use a thin tube with a camera (endoscope) inserted through small openings in the skull, nose, or mouth to remove tumors.

4. MRI-Guided Laser Ablation

A laser is used to destroy tumor tissue using heat under MRI guidance.

5. Stereotactic Radiosurgery

A non-invasive treatment that uses focused radiation beams to destroy tumors without making an incision.

Preparation for Brain Tumor Surgery

Before the surgery, doctors perform several tests and evaluations, including:

● MRI or CT scans to locate the tumor

● Functional MRI to identify important brain areas

● Blood tests and medical evaluation

● Neurological and cognitive tests

Patients are also instructed to stop certain medications and follow fasting instructions before surgery.

Procedure

The exact steps depend on the type of surgery, but the general process includes:

1. Anesthesia – The patient is given general anesthesia or sedation.

2. Accessing the Brain – The surgeon makes an incision in the scalp and may remove a small part of the skull (craniotomy).

3. Tumor Localization – Advanced imaging systems help guide the surgeon to the exact tumor location.

4. Tumor Removal – Special microsurgical instruments remove all or part of the tumor.

5. Closure – The skull bone is replaced and secured with plates or screws, and the incision is closed.

In minimally invasive procedures, smaller incisions and specialized tools are used to reach and remove the tumor.

Recovery After Brain Tumor Surgery

After surgery, patients are monitored in an intensive care or recovery unit. Recovery may include:

● Hospital stay of 2–7 days depending on the surgery

● Monitoring of brain function and vital signs

● Medications to control swelling, seizures, and pain

● Rehabilitation therapies such as physiotherapy, occupational therapy, or speech therapy

Most patients gradually return to daily activities over several weeks, although recovery from major surgery may take months.

Risks and Complications

Although brain tumor surgery is often lifesaving, it carries certain risks, including:

● Infection

● Bleeding

● Brain swelling

● Seizures

● Weakness or paralysis

● Speech or memory problems

● Vision changes

● Leakage of cerebrospinal fluid

Serious complications such as stroke or coma are rare but possible. The risk depends on the tumor’s location and the patient’s overall health.

Benefits of Brain Tumor Surgery

The benefits of brain tumor surgery may include:

● Removal or reduction of tumor size

● Relief from neurological symptoms

● Accurate diagnosis through biopsy

● Improved effectiveness of other treatments

● Better quality of life and survival outcomes
