Neuro surgery – Brain tumor
Primary brain tumours are tumours that start in the brain. They can be cancerous (malignant) or not cancerous (benign). Find out how brain tumours are diagnosed, treated and how they might affect your life. (description)
When normal cells lose the ability to grow old and die, they become abnormal and continue to grow. Large numbers of such abnormal cells form a mass, called as tumors. When these masses are found in the brain, they are called brain tumors. Tumors can either be benign or malignant.
Benign tumors can be removed and do not have any cancer cells. Also, once removed, they are not likely to form again. These tumors do not spread to other parts of the brain and are localized, having clear borders. However, their unchecked growth can press against the normal cells and cause symptoms.
Malignant tumors are those that have cancer cells, interfere with the regular functions of the brain and are life threatening. Such tumors also show aggressive growth, and also spread to the surrounding tissues.
Brain tumors are also generally separated into two categories:
Primary Brain Tumor: those which develop within the brain itself. There are several subtypes, based on the type of cell from which they originate, such as glial cells, neuronal cells, meningeal cells, or Schwann cells.
Metastatic Brain Tumor: those that spread from other parts of the body to the brain. All metastatic tumors are considered malignant, and depending on the type of the primary tumor site, they behave differently. The most common types of metastatic tumors are: lung cancer, breast cancer, renal cell cancer, melanoma, and colon cancer.
Brain tumors are graded in 4 stages: from Grade I (low grade) to Grade IV (high grade). The grading is done after a pathologist looks at the cells. Higher grade tumors are more abnormal looking, grow faster, and are more malignant, as compared to lower grade tumors.
The decisions regarding brain tumor surgeries are made by your cancer care team, before they give you your options. Surgeons, pathologists, medical and radiation oncologists discuss each specific tumor and plan a treatment option.
Your doctors may prescribe surgery, radiation, chemotherapy or a combination of these three, as a part of your specific treatment plan. Surgery involves removal of the tumor and patients are observed for 2 – 3 days following surgery. Some tumors such as astrocytoma, GBM, ependymoma, medulloblastoma are infiltrative tumors and therefore, even after complete removal using surgery, some traces of the tumor may remain.
Fractionated radiation therapy, is another form of treatment, which may be used to deal with the remaining traces of the tumor.
Radiosurgery, is used for benign and metastatic tumors. Here, a very high dose of radiation (only once) is delivered to the tumor, while keeping the surrounding normal tissues safe. Usually radiosurgery is prescribed only for small tumor masses (less than 3cm, in diameter), easily identified by MRI or CT scans, and separate from the brain. For patients with a tumor that can be treated with radiosurgery, the procedure gives very little discomfort and only a short time to recover fully.
First, your doctor will collect your family and your individual medical history, followed by a complete physical exam. Along with this, they will also perform a neurologic exam – including checks for muscle strength, co-ordination, reflexes, and response to pain. They also examine the eyes to look for a swelling cause by tumors pressing on the nerve that connects the eye and the brain. Based off the results, your doctor may recommend one or both of the following:
ACT (or CAT) scan gives detailed pictures of the brain. A computer is linked to an X-ray machine, which provides the pictures. Sometimes, a dye is injected into a vein before the scan, which helps to show differences in the tissues of the brain.
AMRI (magnetic resonance imaging) scan gives pictures of the brain as well. However, it uses a powerful magnet linked to a computer. Unlike CT, MRI scans do not need any radiation. MRI is very useful in diagnosing brain tumors because it can see the tissues lying underneath the bones of the skull. Here too, a dye may be used to increase the chances of detecting a brain tumor.
Your doctor may also recommend performing other tests as well, such as:
Since treatments are continuously improving, we think that it is important for you to be advised by the best doctor in the field, who has experience with your type of tumor. A second opinion is where you meet with more than one doctor to confirm your diagnosis and also, to understand your treatment options.
Second opinions are quite common and most people follow this practise, as it may help to feel more comfortable about your health and the future decisions you make.
Asking for a second opinion is common practice. It may help you feel more comfortable with the health care decisions you make. There are various ways in which a second opinion can give you information. It can:
There are several symptoms of brain tumors, brought on by a number of factors, such as size, location of the tumor, as well as growth rate. Symptoms may be caused by damage to tissue or by pressure on the brain as the tumor grows within the space in the skull. Symptoms may also be caused by swelling and a build-up of fluid around the tumor, called edema. If the rate of growth of a brain tumor is very slow, the symptoms may appear so gradually that they are overlooked for a long time. Also, brain tumor symptoms are often quite vague and non-specific.
The most common symptoms of brain tumors are:
Symptoms are usually slow and progressive in nature.
There are several types of CNS tumors, each with different symptoms, and treatment options. You can browse our list as below:
Neurology is the study and treatment of diseases of the nervous system. Doctors who practice neurology called as Neurologists. Neurosurgery is surgery performed on parts of the nervous system, such as the brain and spinal cord. Doctors who perform the surgery are called neurosurgeons.
If you have a neurologic cancer (CNS cancer), your care team will have surgeons specialized in brain and nervous system surgery, a radiation oncologist, medical oncologist, pathologist, psychologist, rehabilitation therapist and other cancer experts. The neurosurgical team will then review your symptoms with you and obtain a history of your health. Advanced imaging technology, such as MRI, PET scans and/or CT scans, will be used to evaluate the tumor. Biopsies may also be taken, or in urgent cases, full removal of the tumor. Once the team determines the location, type, and grade of the tumor, they will plan a personalized treatment plan for you.

There are no specific reasons as to why brain tumors occur. Although several studies have been completed in this field, a single dominant risk factor has not yet emerged for the formation of brain tumors. As with most cancers, old age is a factor here as well, but no environmental or genetic factors have been implicated yet, for these tumors. Therapeutic radiation is so far an exception, with studies showing it leading to an increase of the risk of brain tumors. The disease is probably the result of several factors acting together.
Following brain tumor treatment, most patients will need continuous follow-up, including exams and MRI brain scans to evaluate for recurrence or other long-term effects of the tumor or treatment.
