Best Brain Tumor Surgery Hospitals in India

Overview

A brain tumor is a growth of abnormal cells in the tissues of the brain. Brain tumors can be benign, with no cancer cells,cancer123 or malignant, with cancer cells that grow quickly. Some are primary brain tumors, which start in the brain. Others are metastatic, and they start somewhere else in the body and move to the brain.

 

 

Brain tumors can cause many symptoms. Some of the most common are:-

  • Headaches, often in the morning
  • Nausea and vomiting
  • Changes in your ability to talk, hear, or see
  • Problems with balance or walking
  • Problems with thinking or memory
  • Feeling weak or sleepy
  • Changes in your mood or behavior
  • Seizures

Doctors diagnose brain tumors by doing a neurologic exam and tests including an MRI, CT scan, and biopsy. Treatment options include watchful waiting, surgery, radiation therapy, chemotherapy, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells. Many people get a combination of treatments.

Brain Tumor Diagnosis:-

To find the cause of your symptoms, your doctor will ask about your personal and family medical history and perform a complete physical examination. In addition to checking general signs of health, your doctor will perform a neurologic exam. This includes checks for alertness, muscle strength, coordination, reflexes and response to pain. Your doctor also examines the eyes to look for swelling caused by a tumor pressing on the nerve that connects the eye and the brain.

Depending on the results of the physical and neurologic examinations, your doctor may request one or both of the following:

  • Computerized Tomography (CT) Scan — Computerized tomography (CT) or computerized axial tomography (CAT) scan is a series of detailed pictures of the brain, created by a computer linked to an X-ray machine. In some cases, a special dye is injected into a vein before the scan. The dye helps to show differences in the tissues of the brain.
  • Magnetic Resonance Imaging (MRI) — Magnetic resonance imaging (MRI) provides pictures of the brain, using a powerful magnet linked to a computer. MRI is especially useful in diagnosing brain tumors because it can “see” through the bones of the skull to the tissue underneath. A special dye may be used to enhance the likelihood of detecting a brain tumor.
  • Angiogram or Arteriogram — These tests are a series of X-rays taken after a special dye is injected into an artery, usually in the area where the abdomen joins the top of the leg. The dye, which flows through the blood vessels of the brain, can be seen on X-rays. These X-rays can show the tumor and connecting blood vessels.
  • Brain Scan — A brain scan reveals areas of abnormal growth in the brain and records them on special film. A small amount of a radioactive material is injected into a vein. This dye is absorbed by the tumor and the growth shows up on the film. The radiation leaves the body within six hours and is not dangerous.
  • Functional Imaging — This test utilizes MRI or magnetic source imaging to identify functional pathways in the brain (motor, visual, language) and alerts the surgeon to potential injury to these pathways during surgery before damage could occur.
  • Myelogram — A myelogram, sometimes called a lumbosacral spine X-ray, is an X-ray or computerized tomography (CT) scan of the spine. A special dye is injected into the cerebrospinal fluid in the spine and the patient is tilted to allow the dye to mix with the fluid. This test may be done when the doctor suspects a tumor in the spinal cord.
  • MR Spectroscopy — This is a modified MRI scan that shows metabolic activity within a brain tumor. This has largely replaced positron emission tomography (PET) scanning due to its superior resolution and accuracy.

Brain Tumor Treatment:-

Treatment for brain tumors depends on a number of factors including the type, location and size of the tumor as well as the patient’s age and general health. Treatment methods and schedules differ for children and adults.

Brain tumors are treated with surgery, radiation therapy and chemotherapy. Our doctors also are studying a vaccine for treating a recurrent cancer of the central nervous system that occurs primarily in the brain, known as glioma.

Depending on your needs, several methods may be used. Our team includes neurosurgeons, medical oncologists, radiation oncologists, nurses, a dietitian and a social worker, who work together to provide the best possible care.

Before treatment begins, most patients are given steroids, drugs that relieve swelling or edema. Your may receive anticonvulsant medicine to prevent or control seizures.

If hydrocephalus is present, you may need a shunt to drain cerebrospinal fluid. A shunt is a long, thin tube placed in a ventricle of the brain and then threaded under the skin to another part of the body, usually the abdomen. It works like a drainpipe. Excess fluid is carried away from the brain and is absorbed in the abdomen. In some cases, the fluid is drained into the heart.

Surgery

Surgery is the usual treatment for most brain tumors. To remove a brain tumor, a neurosurgeon makes an opening in the skull. This operation is called a craniotomy. Whenever possible, the surgeon attempts to remove the entire tumor. If the tumor cannot be completely removed without damaging vital brain tissue, your doctor may remove as much of the tumor as possible. Partial removal helps to relieve symptoms by reducing pressure on the brain and reduces the amount of tumor to be treated by radiation therapy or chemotherapy.

Some tumors cannot be removed. In such cases, your doctor may do only a biopsy. A small piece of the tumor is removed so that a pathologist can examine it under a microscope to determine the type of cells it contains. This helps your doctor decide which treatment to use.

Sometimes, a biopsy is done with a needle. Doctors use a special head frame and CT scans or MRI to pinpoint the exact location of the tumor. The surgeon makes a small hole in the skull and then guides a needle to the tumor. Using this technique to do a biopsy or for treatment is called stereotaxis.

Other advanced techniques during surgery include brain mapping to find functional pathways near tumors, endoscopy to perform biopsies and open spinal fluid pathways through a small scope and advanced frameless stereotaxic computer assisted tumor resections. Intraoperative MRI also is available to help maximize tumor removal.

Radiation Therapy

Radiation therapy, also called radiotherapy, is the use of high-powered rays to damage cancer cells and stop them from growing. It is often used to destroy tumor tissue that cannot be removed with surgery or to kill cancer cells that may remain after surgery. Radiation therapy also is used when surgery is not possible.

Radiation therapy may be given in two ways. External radiation comes from a large machine. Generally, external radiation treatments are given five days a week for several weeks. The treatment schedule depends on the type and size of the tumor and your age. Giving the total dose of radiation over an extended period helps to protect healthy tissue in the area of the tumor.

External radiation may be directed just to the tumor, the surrounding tissue or the entire brain. Sometimes the radiation is also directed to the spinal cord. When the whole brain is treated, the patient often receives an extra dose of radiation to the area of the tumor. This boost can come from external radiation or from an implant.

Radiation also can come from radioactive material placed directly in the tumor, or implant radiation therapy. Depending on the material used, the implant may be left in the brain for a short time or permanently. Implants lose a little radioactivity each day. The patient stays in the hospital for several days while the radiation is most active.

The Gamma Knife, or stereotactic radiosurgery, is another way to treat brain tumors. The Gamma Knife isn’t actually a knife, but a radiation therapy technique that delivers a single, finely focused, high dose of radiation precisely to its target. Treatment is given in just one session. High-energy rays are aimed at the tumor from many angles. In this way, a high dose of radiation reaches the tumor without damaging other brain tissue.

Chemotherapy

Chemotherapy is the use of drugs to kill cancer cells. The doctor may use just one drug or a combination, usually giving the drugs orally or by injection into a blood vessel or muscle. Intrathecal chemotherapy involves injecting the drugs into the cerebrospinal fluid.

Chemotherapy is usually given in cycles. A treatment period is followed by a recovery period, then another treatment period and so on. Patients often don’t need to stay in the hospital for treatment and most drugs can be given in the doctor’s office or clinic. However, depending on the drugs used, the way they are given and the patient’s general health, a short hospital stay may be necessary.

Advances in chemotherapy include direct placement into the tumor cavity using a new technique called convection enhanced delivery.
