Grading of brain cancer is entirely different as compared to the staging of other cancers in the body. Cancer in the breast, lung, colon etc. are staged depending on the possible spread, location of a tumor and lymph node involvement etc. However, brain tumors are graded based on the aggressiveness of the tumor cells under a microscope. The resect ability and the grade of the tumor cells guide a doctor on the treatment decisions. The decision of a brain surgery depends on factors such as the location, spread of a tumour and the general health of the patient.

Types of Brain Tumor Grading:

Grade 1 tumor- These sets of tumors are medically known as the juvenile pilocytic astrocytoma and subependymoma. They are slow growing and non-invasive. There is a likelihood of the patient getting cured with surgery.
Grade 2 tumor- These are brain tumors that do not possess dead cells as part of the tumour. But, they do portray a lot of abnormal cells. Tumors of this type can be categorized under oligodendroglioma, astrocytoma, and ependymoma.
Grade 3 tumor- Tumors of this type are graded based on the cell type of the cancer cells. For instance, an anaplastic astrocytoma is a grade 3 tumor that has no dead cells but possesses dividing cells. In contrast, anaplastic ependymoma and anaplastic oligodendroglioma are grade 3 tumor cells that have dead cells in them.
Grade 4 tumor- Tumors of this type are referred to as glioblastoma. The tumor cells are actively dividing, the growth of blood vessels is witnessed and areas of dead tissue keep expanding.

Treatment options:
Surgery- If the location of a brain tumor is such that it is accessible to a surgeon, the latter goes ahead and removes most of the tumor if not the whole. If, however, the brain tumor cells are placed very near to the surrounding very sensitive brain tissues, a doctor might remove a small portion of the tumor to curb its growth.
Radiation Therapy- This mode of treatment uses high energy X-ray beams to kill targeted cells of the brain. External beam radiation usually targets a small area of the brain. A whole brain radiation, on the other hand, is usually employed when a tumor has spread to most parts of the brain. Radiotherapy is now so evolved that it is highly targeted to tutor cells that kills cancer and spares normal brain .
Chemotherapy- Chemotherapy employs drugs to kill cancer cells. Chemotherapy can either be taken in the form of an IV or in the form of pills. The dosage of chemotherapy is decided based on the concentration of cancer cells, spread frequency, platelet count of the patient etc. The most common chemotherapy drug that is prescribed by doctors to fight cancer cells is temozolomide.

Brain Tumor - Stages and Treatment!

Although surgery is considered to be the first step of treatment in any form of tumor, but its feasibility depends upon the type, size and location of the tumor. It is not necessary that every kind of brain tumor might require surgery.

Indications of Brain Tumor Surgery
- Diagnosis of the type of tumor by taking a sample of the tumor for laboratory examination
- Complete resection of tumor
- Removal of the tumor as much as possible to slow down its growth and improve the symptoms
- Remove the tumor in order to help other treatment
- Provide direct access for other forms of treatment like chemotherapy, radiotherapy etc.
- To relieve pressure caused by tumor on surrounding structures

Types of Brain Tumor Surgery
The different types of surgery that are performed in cases of brain tumor include the following:

Craniotomy: Craniotomy is the most commonly performed procedure to remove brain tumor along with a piece of bone. The removed bone is replaced and the tumor is sent for histopathology (biopsy). The surgery is performed using a high end microscope by any of the following techniques:
- Extended bifrontal craniotomy
- "Eyebrow" craniotomy (supraorbital craniotomy)
- "Keyhole" craniotomy (retro-sigmoid craniotomy)
- Orbitozygomatic craniotomy
- Translabyrinthine craniotomy

Shunt: A narrow piece of flexible tube with a pressure regulated valve in between is called a shunt. This is used to relieve the intracranial pressure caused by obstruction of the natural brain fluid, Cerebrospinal fluid (CSF) pathway by tumor mass. The procedure involves insertion of a drainage system into the brain to remove or drain excess of blocked fluid into the peritoneal cavity.

Stereotactic surgery: This surgery is done by creating a three dimensional image called stereotaxy using computers. It aims to find out the location and position of the tumor. In fact it can also be done to aid tumor removal, implant radiation pellets or for other treatments.

Embolization: It is a procedure used to reduce the amount of blood supply to a tumor by blocking the blood flow in the selected arteries. It is generally performed before the main surgery.

Endoscopy and endoscope assisted surgery: Endoscope is a tool, which helps to closely visualize the tissue through small openings in difficult to reach areas. This tool can be used in various brain surgeries to precisely reach the target location without damaging the adjacent structures.

Adjuvant modalities to improve outcome: In addition to above mentioned surgeries, following surgeries may also be performed in relation to brain tumor treatment:
- Laser surgery
- Photodynamic laser surgery
- Ultrasonic aspiration
- Fluorescence guided surgery (FGS)
- Electrophysiological monitoring

Brain Tumor Surgery

There are two primary factors that are more likely to cause a stroke in a person i.e age and a family history. While both are inevitable, this necessarily doesn t have to be the fate of a person. Brain stroke is entirely preventable as with the case of other diseases. By working on the potential health risk factors, a stroke can be prevented. Here is a list of few such steps which, when followed can pay rich dividends to a person facing the risk of a brain stroke:

Blood Pressure: Blood pressure is the single most important factor that can increase the chance of a brain stroke. If a perfect blood pressure reading seems too difficult to achieve, a more realistic blood pressure target of 140/190 should be aimed for. Some of the common steps in order to achieve an acceptable blood pressure figure include reducing salt in the diet, exercising on a daily basis, regular intake of fresh fruits & vegetables and fast processed food containing processed fats. Finally, quitting drinking and smoking goes a long way in ensuring that a person is safe from strokes.

Losing Weight: Obesity increases the risk of diabetes and blood pressure subsequently increasing the risk of a stroke. Being overweight, therefore greatly increases the odds of a stroke. A BMI of 25 should be maintained by engaging in activities such as walking, running and playing on a daily basis.

Regular Exercise: Exercise is a clear mandate for people facing an increased risk of brain strokes. A moderate intensity exercise schedule for a minimum of 5 days per week is necessary. Some simple steps in order to achieve this include taking the stairs while climbing, joining a fitness club, 30 minutes of daily walk in a day etc.

Moderate Drink: Surprising as it may sound, moderate drinking on a daily basis can dramatically reduce the risk of a brain stroke. Red wine should be the choice of preference in this case. It should be ensured that the level of drinking does not surpass more than a glass. Regular drinking in excessive quantity can increase the chance of brain stroke.

Check For Atrial Fibrillation: This is a disease that is related to the heart due to an irregular heartbeat. There is a possibility of the clots travelling to the brain causing a brain stroke. Certain possible symptoms of this disease such as palpitation of heart and shortness of breath should be checked with a doctor to negate the chance of brain stroke. Certain blood thinners like warfarin and aspirin can shield against atrial fibrillation. A doctor has to be consulted before starting any medication related to the heart.

Top Ways To Prevent A Brain Stroke

Brain tumours vary in shape and size and the same is the case with their symptoms. The location of the tumour affects the symptoms greatly. Just like in any other type of a malignant tumour, brain tumour has a rapid growth and proliferation of abnormal cells that may have its origin in affected site or areas adjacent to it. As per studies, every 2 in 1,00,000 people are said to be affected by brain tumour in India. However, it may come as a relief to some as not all brain tumors are cancerous or life threatening. Some are benign tumors and seldom pose any threat to the affected individual.

Types of Brain Tumor
Brain tumors may be primary or secondary.

Primary brain tumor: Here the abnormal mass of cells that originated in the brain do not metastasize to the other organs. Based on their location in the brain, the primary brain tumors may be of the following types.
Gliomas: One of the most common types of primary brain tumors, gliomas can have their origin in the spinal cord or the brain. Some of the common types of gliomas include Astrocytomas (originates in the cerebrum of the brain), Glioblastomas (these tumors form from the Astrocytes which form the supportive tissues of the brain), Ependymoma (these develop from the ependymal cells which are present within the CNS), Oligodendrogliomas (these tumors are found to arise from the oligodendrocytes).
Schwannomas: Also called as Acoustic neuromas, these primary brain tumors form on the nerves that play an important role in regulating the balance and hearing from the inner ear to the brain.
Meningiomas: These type of tumors are usually benign and have their origin in the meninges (membranes surrounding the spinal cord and the brain).
Primitive neuroectodermal tumors (PNETs): Primitive neuroectodermal tumors (PNETs) are rare malignant tumors that originate from the fetal (embryonic) cells in the brain.
Pituitary adenomas: As the name suggests, these tumors arise from the pituitary gland located at the base of the brain.
Medulloblastomas: Common among the children, these malignant primary tumors develop in the brain (lower back) and gradually spread via the spinal fluid.
Other types of primary brain tumors include Craniopharyngiomas and the Germ cell tumors.
Secondary brain tumors: Unlike the primary brain tumors, these tumors have their origin in the other body parts and organs (mostly in the lungs, skin, colon, breast, and kidney) and then gradually metastasize to the brain. The secondary brain tumors are found to be more common.
Symptoms or warning signs associated with brain tumors:
Some of the signs and symptoms that may be indicative of a brain tumor include

People with brain tumors often get seizures (due to the irritation caused by the tumors in the brain).
A headache (mild to severe depending on the part of the brain affected by the tumor).
A person experiences numbness or a tingling sensation in the legs and arms.
There may be difficulties in walking or balancing.
A person finds it difficult to concentrate.
There may be some problems with hearing, speech or even vision.
A person may experience weakness restricted to only one part of the body.
The symptoms may not necessarily indicate a brain tumor but it is always wise not to neglect the symptoms either.

Brain Tumor - What Are The Types?

There is no trustworthy evidence regarding what causes brain tumors, but there are a few risk factors that have been substantiated through research. Children and young people who receive radiation around the head are susceptible to developing tumors in the brain once they grow up. Also, people with a certain kind of rare genetic condition like neurofibromatosis may develop a brain tumor though such cases are very few in number. Age is also an important factor as people aged over 65 years are diagnosed with brain tumors at quadruple times higher than children and younger people.

Types of Brain Tumours-

A primary brain tumor originates in the brain, and they may or may not be cancerous. Some tumors can be benign, which do not spread in the surrounding tissues and are not very malicious. However, that does not signify that they will not cause any harm over time. Sometimes these tumors can be severe and cause a threat to the life of the sufferer. The National Cancer Institute reports that approximately there were 23, 380 fresh cases of brain tumors in 2014.

Identifying the Symptoms of Brain Tumors...

The symptoms of the brain tumor are dependent on various factors such as the size, type as well as the exact location of the tumor. These symptoms are triggered when any tumor is pressed or clashed against a nerve or disturbs a part of the brain. Symptoms are also felt when any tumor particle blocks the fluid flowing around the brain or when there is a swelling in the brain owing to the build-up of fluid.

Common symptoms include- headaches that get worse in the morning, nausea along with vomiting, an alteration in the speech, hearing and imbalances in walking and movement, mood swings, change in personality and ability to concentrate or remember things and seizures or convulsions.

Treatment for Brain Tumor-

Surgery is normally the most usual treatment for brain tumors, and the patient is given anaesthesia, and the scalp is shaved before the surgery. Then, craniotomy is performed to open the skull, and the surgeon removes a bone piece out of the skull. Then the tumor is removed as much as possible. The bone is then restored back, and the incision on the scalp is closed. Sometimes surgery is not viable in case the tumor has developed in the brain stem or some other complex parts.

Neurosurgeons can surgically remove some tumors completely (called resection or complete removal). If the tumor is near sensitive areas of the brain, neurosurgeons will only be able to remove part of it (called partial removal). Even partial removals can relieve symptoms and facilitate or increase the effectiveness of other treatments.

The role of surgery in treating brain tumors

Surgery can provide:

- The complete removal of some brain tumors
- A sample to enable doctors to diagnosis the tumor and recommend the most appropriate treatment
- Better quality of life:
- Reduced symptoms and improved ability to function (e.g., to think, speak or see better)
- Less pressure within the skull from the tumor
- A longer life

In case you or any of your near ones is affected with brain tumor, you should visit the doctor to know the possible treatments other than surgery and other important questions related to brain tumor.

Brain Tumor - Causes, Symptoms and Treatment

A stroke, also called cerebrovascular accident (CVA), cerebrovascular insult(CVI), or brain attack, occurs when a part of the brain is deprived of blood flow. When the brain cells are deprived of oxygen they begin to die. When brain cells die, the functions controlled by that part of the brain also stops, which results in different types of disabilities among stroke survivors.

There are two types of strokes

Hemorrhagic
Ischemic stroke
The first is caused when a brain aneurysm or a weak blood vessel bursts. Most of the time, this type of stroke leads to death. The second one happens when a clot blocks the flow of blood to the brain. Patients suffering from stroke suffer from various side-effects, the most common ones being paralysis or loss of feeling in a certain part of the body, problem in understanding or talking and loss of vision in one side. The side-effects start showing up regularly after a person has had a stroke.

In certain conditions, blood flow to a certain part of the brain stops for only some time and hence the body suffers stroke like symptoms which only last a couple of hours before disappearing. This is known as a transient ischemic attack (TIA). Unfortunately, the effects of a stroke can be debilitating and also permanent. Hence its important to know the symptoms of a stroke and rush the patient to a doctor as soon as possible. Sometimes early treatment can save a lot of damage.

The primary symptoms of stroke are as follows:

Confusion and problems with talking and comprehension
Headache along with alteration of consciousness or vomiting
Numbness of the face, arms or legs, especially on one side of the body
Issue with seeing, in one or both eyes
Inability to walk with stability, including disrupted coordination
Problems with the bladder and bowel control
Acute depression
Body temperature fluctuates, and pain worsens with movement
Paralysis on one side of the body along with fatigue
Problem in expressing or controlling emotions
Risk Factors:

Hypertension
Diabetes
Increased Cholesterol
Smoking
Obesity
Sedentary Lifestyle
Diagnosis of stroke

Several tests are carried out to determine the type of stroke acquired. They are:

Physical examination, which involves observing the patient's overall condition.
Blood tests
CT scans
MRI scans
Cerebral angiogram
Echocardiograms
Stroke is a fatal brain disease and can cause permanent damage to your system so its best to check with your doctor to know how you can prevent it.
