Brain Tumours

Overview of Brain Tumours

A brain tumour is an abnormal growth of cells in the brain. Brain tumours occur due to mutational changes in the genomes of brain cells.

Signs and Symptoms of Brain Tumours

A brain tumour is an abnormal growth of cells in the brain.

Brain tumours(برین ٹیومر)  are classified into two types on the basis of their spread. Primary brain tumours begin in the brain cells or nearby tissues such as meninges or cranial nerves. Secondary brain tumours are tumours that arise from another part of the body but later invade brain tissues.
Brain tumours occur due to mutational changes in the genomes of brain cells. The treatment approaches used for brain tumours depends on:

  • The location of the cancer
  • Size of the cancer
  • The aggressiveness of the cells
  • Spread of the tumours (localized or metastatic)

Types of Brain Tumours

The symptoms of brain tumours are different for each case. These symptoms depend on the tumours:

  • Size
  • Location
  • Rate of growth

Some common signs and symptoms of brain tumours may include:

  • New onset or change in the pattern of headaches
  • Hearing problems
  • Personality or behaviour changes
  • Severe nausea or vomiting
  • Confusion in everyday matters
  • Headaches that gradually become more frequent and more severe
  • blurred or double vision
  • Speech difficulties
  • Difficulty with balance
  • Gradual loss of sensation
  • Seizures without any history

Classification of Brain Tumours

Brain tumours are classified into two types on the basis of their spread such as:

Primary Brain Tumours

Primary brain tumours begin in the brain cells or nearby tissues such as meninges or cranial nerves. In adults, primary brain tumours are less common as compared to secondary brain tumours.
Primary brain tumours exist in different forms. Each type is named according to the type of cell affected. These include:

Secondary Brain Tumours

Secondary brain tumours are tumours that arise from another part of the body but later invade brain tissues. These types of tumours are called metastatic and their spread is known as metastasizes.
These brain tumours often develop in people who have a cancer history. But sometimes, these tumours can be a sign of tumours at some part of the body.
In adults, secondary brain tumours are more common as compared to primary brain tumours.

Following cancers metastasize to other organs of the body:

  • Breast cancer
  • Kidney cancer
  • Colon cancer
  • Lung cancer
  • Melanoma

Risk Factors of Brain Tumours

Brain tumours occur due to mutational changes in the genomes of brain cells. Some changes cause the overgrowth of cells. These cells grow rapidly until the normal cells die. Consequently, these abnormal cells crowd out the normal cells and lead to tumours.

Prevention

There are some factors that increase the risk of brain tumours such as:

  • Exposure to Radiation: If you have previously received radiation therapy for cancer your chances of developing brain tumours are increased.
  • Family History: Your risk of developing brain tumours is increased if your parents or siblings have a brain tumours history.

Diagnosis

There is no concrete way to prevent brain tumours. But following the given below preventive strategies can help a person:

  1. Avoid unnecessary exposure to radiations
  2. Quit smoking
  3. Avoid exposures to carcinogenic chemicals
  4. Remember to avoid exposure to pesticides or insecticides

Treatment of Brain Tumours | When to Consult a Doctor

If a brain tumour is suspected, the following tests are often recommended.

Neurological Exam

In the neurological exam following areas are examined:

  • Vision
  • Hearing
  • Balance
  • Coordination
  • Strength
  • Reflexes

Problems in any of these areas provide help in diagnosing the part of the brain affected by tumours.

Imaging Tests

Magnetic resonance imaging (MRI) is the most common imaging test used to diagnose brain tumours. Sometimes, a dye is injected in the vein through the arm to facilitate the MRI study. These days more specialized MRI scans are available such as:

  • Functional MRI
  • Magnetic resonance spectroscopy
  • Perfusion MRI

Positron emission tomography (PET) is another computerized imaging test used for tumours diagnosis. But this test is a general imaging test and not useful for brain tumour diagnosis.

CT or PET Scan

These scans are performed if your doctor speculated that you have a secondary brain tumour. These imaging tests determine the origin point of tumours.

Biopsy

A biopsy is performed to collect tissues from the area affected by the tumours. Tests can identify the cancerous cells and the type of cancer.

A biopsy can be performed in two different ways such as:

  • Needle Biopsy: In this biopsy procedure, a thin needle is inserted into the tumours and a small piece of tissue is removed.
  • Surgical Biopsy: In a surgical biopsy, either an incision is made to remove the entire tumours or a small part of the cancer is removed.
