Brain tumors are composed of cells that exhibit unrestrained growth in the brain. The major areas of the brain have one or more specific functions.
They can be benign (noncancerous, meaning that they do not spread elsewhere or invade surrounding tissue) or malignant (cancerous).Cancerous brain tumors are further classified as either primary or secondary tumors.

Alternative Names of Brain Tumor are: Gliomas; Medulloblastomas

Complications of Brain Tumors
Brain tumors can be extremely serious, even when noncancerous. A non malignant brain tumor can do damages as it grows bigger within the rigid skull and starts pressing on the brain. The specific effects of tumor on the brain can cause-

• Seizures
• Mental changes
• Changes in mood and personality
• Emotional changes

Depending on the size and location, a brain tumor can cause temporary or permanent brain damage. The brain is divided into different parts that are responsible for variety of functions.

Causes of Brain Tumors

• The tumor cell destroys the brain cell which cause to the swelling of brain high pressure in the brain.
• Some genetically inheritance condition also causes to the growth of brain tumor.
• Vinyl chloride is a cancer causing substance which also causes to the brain tumor.
• The genetic conditions like mutations and deletions of tumor suppressor genes are responsible for the brain tumor.
• The people who works in manufacturing industry and chemical plats they have high risk of brain tumor.

Signs & Symptoms of Brain Tumors

The symptoms of brain tumors depend on tumor size, type and location. Symptoms may be caused when tumor presses on the nerve or damages a certain area of the brain. They also may be caused when the brain swells or fluid builds up within the skull.
The most common symptoms of brain tumors are -

• Headaches -usually worse in the morning.
• Nausea or Vomiting.
• Changes in speech, vision or hearing.
• Problems balancing or walking.
• Changes in mood, personality, or ability to concentrate.
• Problems with memory.
• Muscle jerking or twitching (seizures or convulsions)
  • Seizures: A seizure is a sudden, involuntary change in behavior, muscle control, consciousness, and/or sensation. Symptoms of a seizure can range from sudden, violent shaking and total loss of consciousness to muscle twitching or slight shaking of a limb. Staring into space, altered vision, and difficulty in speaking are some of the other behaviors that a person may exhibit while having a seizure.
• Numbness or tingling in the arms or legs.

These symptoms are not sure signs of a brain tumor. Anyone with these symptoms should see a doctor. Only a doctor can diagnose and treat the problem.

Diagnosis of Brain Tumors

If a person has symptoms that suggest a brain tumor, the doctor may perform one or more of the following procedures:

• Physical exam - The doctor checks general signs of health.
• Neurologic exam - The doctor checks for alertness, muscle strength, coordination, reflexes, and response to pain. The doctor also examines the eyes to look for swelling caused by a tumor pressing on the nerve that connects the eye and brain.
• CT scan - An x-ray machine linked to a computer takes a series of detailed pictures of the head. The patient may receive an injection of a special dye so the brain shows up clearly in the pictures. The pictures can show tumors in the brain.
• MRI - A powerful magnet linked to a computer makes detailed pictures of areas inside the body. These pictures are viewed on a monitor and can also be printed. Sometimes a special dye is injected to help show differences in the tissues of the brain. The pictures can show a tumor or other problem in the brain.

The doctor may ask for other tests:

• Angiogram
• Skull x-ray
• Spinal tap - The doctor may remove a sample of cerebrospinal fluid (the fluid that fills the spaces in and around the brain and spinal cord). This procedure is performed with local anesthesia. The doctor uses a long, thin needle to remove fluid from the spinal column. A spinal tap takes about 30 minutes. 
• Myelogram
• Biopsy can also be done - needle biopsy, stereotactic biopsy and Biopsy at the same time as treatment.

Treatments of Brain Tumor

People with brain tumors have several treatment options. Depending on the tumor type and stage, patients may be treated with surgery, radiation therapy, or chemotherapy. Some patients receive a combination of treatments.
At any stage of disease,

Prevention of Anemia

• Eat a healthy balanced diet and ensure the diet contains good sources of iron, folic acid and vitamin B12.
• Cut down alcohol consumption.
• For strict vegetarians, Vitamin B12 supplements should be taken to avoid deficiency.

When to seek Medical Advice

• As anemia causes a shortage of oxygen, the main symptom is usually chronic tiredness and palpitations.
• Pale appearance.
• Shortness of breath and dizziness.
• Fainting.
• Angina.
• A red, sore tongue and a reduced sense of taste, this is usually only a symptom with folic acid and vitamin B12 deficiency anemia.
