Brain tumor facts
Primary brain tumors can be either malignant (contain cancer cells) or benign (do not contain cancer cells).
Brain tumors can occur at any age.
The exact cause of brain tumors is not clear.
Physicians group brain tumors by grade (the way the cells look under a microscope).
Brain tumors are classified as grade I, grade II, or grade III, or grade IV
There most common type of primary brain tumors among adults are astrocytoma, meningioma, and oligodendroglioma.
The most common type of primary brain tumors in children are medulloblastoma, grade I or II astrocytoma, ependymoma, and brain stem glioma.
Studies have found risk factors for brain tumors to include ionizing radiation from high dose X-rays (for example, radiation therapy where the machine is aimed at the head), and family history.
The symptoms of brain tumors depend on their size, type, and location.
The most common symptoms of brain tumors include headaches; numbness or tingling in the arms or legs; seizures, memory problems; mood and personality changes; balance and walking problems; nausea and vomiting; changes in speech, vision, or hearing.
Brain tumors are diagnosed by the doctor based on the results of a medical history and physical examination and results of a variety of specialized tests of the brain and nervous system.
Treatment of a brain tumor depends on the type, location, and size of the tumor, as well as the age and health of the patient.
Options for brain tumor treatment include surgery, radiation therapy, and chemotherapy (or a combination of treatments).
What are the tumor grades and types?
When most normal cells grow old or get damaged, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when the body doesn't need them, and old or damaged cells don't die as they should. The buildup of extra cells often forms a mass of tissue called a growth or tumor.
Primary brain tumors can be benign or malignant:
Benign brain tumors do not contain cancer cells:
Usually, benign tumors can be removed, and they seldom grow back.
Benign brain tumors usually have an obvious border or edge. Cells from benign tumors rarely invade tissues around them. They don't spread to other parts of the body. However, benign tumors can press on sensitive areas of the brain and cause serious health problems.
Unlike benign tumors in most other parts of the body, benign brain tumors are sometimes life threatening.
Benign brain tumors may become malignant.
Malignant brain tumors (also called brain cancer) contain cancer cells:
Malignant brain tumors are generally more serious and often are a threat to life.
They are likely to grow rapidly and crowd or invade the nearby healthy brain tissue.
Cancer cells may break away from malignant brain tumors and spread to other parts of the brain or to the spinal cord. They rarely spread to other parts of the body.
Tumor grade
Doctors group brain tumors by grade. The grade of a tumor refers to the way the cells look under a microscope:
Grade I: The tissue is benign. The cells look nearly like normal brain cells, and they grow slowly.
Grade II: The tissue is malignant. The cells look less like normal cells than do the cells in a Grade I tumor.
Grade III: The malignant tissue has cells that look very different from normal cells. The abnormal cells are actively growing (anaplastic).
Grade IV: The malignant tissue has cells that look most abnormal and tend to grow quickly.
Cells from low-grade tumors (grades I and II) look more normal and generally grow more slowly than cells from high-grade tumors (grades III and IV).
Over time, a low-grade tumor may become a highgrade tumor. However, the change to a high-grade tumor happens more often among adults than children.

Survival rates can be calculated by different methods for different purposes. The brain cancer survival rates presented here are based on the relative survival rate. The relative survival rate measures the survival of patients with brain cancer in comparison to the general population to estimate the effect of cancer. The overall 5-year relative brain cancer survival rate for 1995-2001 was 33.3 percen
I did a bit of research so that the CVs get a solution to tragic track they have come up with.If at all Indira is having this condition,than she should have a benign tumor,which can be removed;and I really hope it is Rishi,who takes her to an expert brain surgeon,and we get back the positive vibe in the drama.

Brain Cancer Survival
The 5-year brain cancer survival rate is the percentage of people who are alive 5 years after their diagnosis, whether they have few or no symptoms of brain cancer, are free of disease, or are having treatment. The brain cancer survival rate is based on large groups of people and cannot be used to predict what will happen to a particular patient.

The brain cancer survival rate indicates the percentage of people with a certain type and stage of brain cancer who survive the disease for a specific period of time after their diagnosis. In most cases, statistics refer to the 5-year brain cancer survival rate. The 5-year brain cancer survival rate is the percentage of people who are alive 5 years after a brain cancer diagnosis, whether they have few or no signs or symptoms of brain cancer, are free of disease, or are having treatment for brain cancer. The brain cancer survival rate is based on large groups of people, and it cannot be used to predict what will happen to a particular patient. No two patients are alike, and brain cancer treatment and responses to treatment vary greatly.

Factors Influencing Brain Cancer Survival
In general, the brain cancer survival rate will depend on:
- The type of brain cancer (see Types of Brain Tumors)
- The size and location of brain cancer
- The brain cancer stage
- The brain cancer grade
- The patient's general health.
