The brain is a soft, spongy mass of tissue. It is protected by the bones of the skull and three thin membranes called meninges. Watery fluid called cerebrospinal fluid cushions the brain. This fluid flows through spaces between the meninges and through spaces within the brain called ventricles. A network of nerves carries messages back and forth between the brain and the rest of the body. Some nerves go directly from the brain to the eyes, ears, and other parts of the head. Other nerves run through the spinal cord to connect the brain with the other parts of the body. Within the brain and spinal cord, glial cells surround nerve cells and hold them in place. The brain directs the things we choose to do (like walking and talking) and the things our body does without thinking (like breathing). The brain is also in charge of our senses (sight, hearing, touch, taste, and smell), memory, emotions, and personality.
What are benign and malignant braintumors?
Braintumors can be benign or malignant. Benign braintumors do not contain cancer cells - Usually, benign tumors can be removed, and they seldom grow back. The border or edge of a benign braintumor can be clearly seen. Cells from benign tumors do not invade tissues around them or 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 braintumors are sometimes life threatening. Very rarely, a benign braintumor may become malignant.
Malignant braintumors contain cancer cells - Malignant braintumors are generally more serious and often are life threatening. They are likely to grow rapidly and crowd or invade the surrounding healthy brain tissue. Very rarely, cancer cells may break away from a malignant braintumor and spread to other parts of the brain, to the spinal cord, or even to other parts of the body. The spread of cancer is called metastasis. Sometimes, a malignant tumor does not extend into healthy tissue. The tumor may be contained within a layer of tissue. Or the bones of the skull or another structure in the head may confine it. This kind of tumor is called encapsulated.
What causes and who is at risk for brain tumors?
No one knows the exact causes of braintumors. Doctors can seldom explain why one person develops a braintumor and another does not. However, it is clear that braintumors are not contagious. No one can "catch" the disease from another person. Research has shown that people with certain risk factors are more likely than others to develop a braintumor. A risk factor is anything that increases a person's chance of developing a disease.
The following risk factors are associated with an increased chance of developing a primary braintumor-
Being male - In general, braintumors are more common in males than females. However, meningiomas are more common in females.
Race - Braintumors occur more often among white people than among people of other races.
Age - Most braintumors are detected in people who are 70 years old or older. However, braintumors are the second most common cancer in children. Braintumors are more common in children younger than 8 years old than in older children.
Family history - People with family members who have gliomas may be more likely to develop this disease.
Being exposed to radiation or certain chemicals at work.
Radiation - Workers in the nuclear industry have an increased risk of developing a braintumor.
Formaldehyde - Pathologists and embalmers who work with formaldehyde have an increased risk of developing braintumor. Scientists have not found an increased risk of braintumor among other types of workers exposed to formaldehyde.
Vinyl chloride - Workers who make plastics may be exposed to vinyl chloride. This chemical may increase the risk of braintumors.
Acrylonitrile - People who make textiles and plastics may be exposed to acrylonitrile. This exposure may increase the risk of braintumor.
What is the treatment for braintumors?
Many people with braintumors want to take an active part in making decisions about their medical care. They want to learn all they can about their disease and their treatment choices. However, shock and stress after a diagnosis of a braintumor can make it hard to think of everything to ask the doctor. It often helps to make a list of questions before an appointment. To help remember what the doctor says, patients may take notes or ask whether they may use a tape recorder. Some also want to have a family member or friend with them when they talk to the doctor - to take part in the discussion, to take notes, or just to listen. The doctor may refer the patient to a specialist, or the patient may ask for a referral. Specialists who treat braintumors include neurosurgeons, neuro oncologists, medical oncologists, and radiation oncologists. The patient may be referred to other health care professionals who work together as a team. The medical team may include a nurse, dietitian, mental health counselor, social worker, physical therapist, occupational therapist, and speech therapist. Children may need tutors to help with schoolwork.
Brain Tumour treatment is available in Indiaat various world class hospitals that are equipped with the latest medical technology. And besides this the medical staff at these hospitals speaks English fluently. So communication is not a problem.
