What is a brain tumor?

A brain tumor is a collection, or mass, of abnormal cells in your brain. Your skull, which encloses your brain, is very rigid. Any growth inside such a restricted space can cause problems. Brain tumors can be cancerous (malignant) or noncancerous (benign). When benign or malignant tumors grow, they can cause the pressure inside your skull to increase. This can cause brain damage, and it can be life-threatening.

Brain tumors are categorized as primary or secondary. A primary brain tumor originates in your brain. Many primary brain tumors are benign. A secondary brain tumor, also known as a metastatic brain tumor, occurs when cancer cells spread to your brain from another organ, such as your lung, breast, colon, kidney, skin or liver. Hence secondary brain tumors are always cancerous and usually fatal.


What are the symptoms of a brain tumor?

Symptoms of brain tumors depend on the location and size of the tumor. Some tumors cause direct damage by invading brain tissue and some tumors cause pressure on the surrounding brain. You’ll have noticeable symptoms when a growing tumor is putting pressure on your brain tissue.

Headaches are a common symptom of a brain tumor. You may experience headaches that:

  • are worse in the morning when waking up
  • occur while you’re sleeping
  • are made worse by coughing, sneezing, or exercise
You may also experience:
  • vomiting
  • blurred vision or double vision
  • confusion
  • seizures , loss of consciousness, uncontrollable twitching in any part of body
  • weakness of a limb or part of the face
  • a change in mental functioning
Other common symptoms include:
  • clumsiness
  • memory loss
  • difficulty writing or reading
  • changes in the ability to hear, taste, or smell
  • decreased alertness, which may include drowsiness and loss of consciousness
  • difficulty swallowing
  • dizziness or vertigo
  • eye problems, such as drooping eyelids and unequal pupils
  • uncontrollable movements
  • hand tremors
  • loss of balance
  • loss of bladder or bowel control
  • numbness or tingling on one side of the body
  • trouble speaking or understanding what others are saying
  • changes in mood, personality, emotions, and behavior
  • difficulty walking
  • muscle weakness in the face, arm, or leg

Symptoms of pituitary tumors

The following symptoms can occur with pituitary tumors:
  • nipple discharge, or galactorrhea
  • lack of menstruation in women
  • development of breast tissue in men
  • enlargement of the hands and feet
  • sensitivity to heat or cold
  • increased amounts of body hair, or hirsutism
  • low blood pressure
  • obesity
  • changes in vision, such as blurry vision or tunnel vision

How are brain tumors diagnosed?

Diagnosis of a brain tumor begins with a physical exam and a listening to your medical history. The physical exam includes a very detailed neurological examination. Your brain tumor doctor in Dubai will conduct a test to see if your cranial nerves are intact. These are the nerves that originate in your brain. Your brain tumor doctor in Dubai will look inside your eyes with an ophthalmoscope, which is an instrument that shines a light through your pupils and onto your retinas. This allows your doctor to check how your pupils react to light. It also allows your doctor to look directly into your eyes to see if there’s any swelling of the optic nerve. When pressure increases inside the skull, changes in the optic nerve can occur.


The doctor may also evaluate your:
  • muscle strength
  • coordination
  • memory
  • ability to do mathematical calculations

MRI of the head

If a routine MRI shows a suspicious abnormality, a special dye can be used to help your brain tumor doctor in Dubai to detect tumors. An MRI is different from a CT scan because it doesn’t use radiation, and it provides much more detailed pictures of the structures of the brain itself.

Treatment of brain tumors

The treatment of a brain tumor, of course depends on:
  • the type of tumor
  • the size of the tumor
  • the location of the tumor

After a proper localization and diagnosis your brain tumor doctor in Dubai may refer you either for a cyber-knife procedure which is non-invasive or an endoscopic removal of the tumor which is minimally invasive or in the worst case scenario an open skull surgery.
