What Is A Brain Tumor

Your brain is made up of cells, sometimes the cells go haywire and form into a cluster that becomes abnormal. They can also be cancerous. When, this happens it’s called a Brain Tumor. There are lots of different types of tumor 130 to be exact. The two most common are called primary and secondary. A primary tumor is formed inside the skull. The secondary is formed in another part of the body and then spreads to the brain.

Different Types Of Brain Tumor

Glioblastoma multiforme, is one of the fastest growing and most aggressive types of tumor that forms on the supportive tissue of the brain. Glioblastoma is the most common type of brain cancer. It, can appear in any part of the brain, but they develop most commonly in the frontal and temporal lobes.

Astrocytomas, which are the most common CNS tumors, can grow anywhere in the brain or spinal cord, and they develop from small, star-shaped cells called astrocytes. In adults, astrocytomas most often occur in the cerebrum, the largest part of the brain. The cerebrum uses sensory information to tell us what’s going on around us and how the body should respond. The cerebrum also controls speech, movement and emotions, as well as reading, thinking and learning.

Brain stem gliomas are a type of astrocytoma that forms in the brain stem, which controls many vital functions, such as body temperature, blood pressure, breathing, hunger and thirst. The brain stem also transmits all the signals to the body from the brain. The brain stem is in the lowest part of the brain and connects the brain and spinal cord. Tumors in this area can be difficult to treat because of where they are located. Most brain stem gliomas are high-grade astrocytomas.

Pituitary tumors are lumps that form in the pituitary gland. This is a small pea sized gland that sits inside the skull, just below the brain and above the nasal passages. The pituitary gland produces hormones that control the levels of other hormones secreted by endocrine glands throughout the body, giving it an important role in controlling key body functions and the hormonal system.

Pituitary tumors make up between 9 and 12 % of all brain tumors.

The majority of pituitary tumors are called pituitary adenomas, these are normally benign growths that don’t spread beyond the skull area. These types of tumors are not cancerous, but they can cause other medical issues because they are located very near to the brain and this can make the pituitary gland produce an excess of hormones.

Pituitary cancers, called pituitary carcinomas, are very rare.

Medulloblastomas are very fast-growing brain tumors that develop from the neurons of the cerebellum. The cerebellum controls movement, balance and posture. These tumors are usually found in children or young adults as opposed to older people.

Malignant or Benign

Cancerous tumors are called malignant and are considered to be very dangerous. A noncancerous tumor is called benign, although not as dangerous because it doesn’t have cancerous cells it is still a problem because it’s a mass on the brain that should not be there. The mass grows bigger and causes pressure to build up which can cause you to have brain damage.


Brain Tumor Symptoms

The most common symptom is a headache, that occurs when you are sleeping. It can be made worse by coughing or sneezing and also are more prominent in the morning when you have just woken up.

Other symptoms include:

  • Being physically sick
  • blurry vision or double vision

  • dizziness or vertigo symptoms
  • problems with your eyes, such as drooping eyelids or unequal pupils
  • movements you cannot control such as shaky hands
  • losing your balance
  • No control of the bladder or bowel
  • numbness or tingling on one side of the body
  • trouble speaking or comprehending what people are saying to you
  • changes in personality, emotions, moods and behavior
  • difficulty with walking
  • muscle weakness in the face, arms, or legs

Pituaritary Tumor Symptoms

  • Discharge from the nipples
  • lack of menstrual cycle (women)
  • development of breast tissue in men
  • sensitivity to heat or cold
  • enlarged hands and feet
  • increased amounts of body hair
  • low blood pressure
  • changes in vision, such as blurry vision or tunnel vision
  • obesity



How Brain Tumors Are Diagnosed

The doctor will carry out an examination that includes a very detailed neurological examination. He or she will also do a test to see if your cranial nerves are intact. These nerves originate in your brain.

Your doctor will also look inside your eyes with an ophthalmoscope, This instrument shines a light through your pupils and onto your retinas. This allows the doctor to see 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 the pressure inside the skull increases, it can cause changes to the optic nerve.

The doctor will also look at

  • Your coordination
  • How your memory functions
  • muscle strength
  • Your ability to do mathematical sums

Your doctor may possibly do more tests after they finish the physical examination.

These could include:

A Biopsy

A small piece of the tumor is removed during a biopsy. A specialist called a neuropathologist will looks at it. The biopsy will say if the tumor cells are benign or malignant. It will also determine whether the cancer started in your brain or from another part of your body.

An Angiography

This procedure uses a colored dye that’s injected into your artery, generally in the groin region. The dye travels through the arteries into your brain. It allows the doctor to see what the blood supply of the tumors looks like. This information is then used if you later have surgery.

A CT Scan

CT scans are ways for the doctor to get a more detailed picture of your body than they could with an X-ray machine. This can be done with or without contrast. ( contrast is a dye) that helps to see blood vessels more clearly.



X-rays of the Skull

Brain tumors can get very huge that they cause fractures in the bones of the skull, and specific X-rays can show if this has happened. These X-rays can also see calcium deposits, which are sometimes found inside a tumor. Calcium deposits may also be found in your bloodstream if your cancer has moved to your bones.


If, you have an MRI scan carried out on your head, a special dye is used to help the doctor to identify any tumors that may be present. An MRI is different from a CT scan because it does not use radiation, and it usually provides a much more detailed picture of the structure of the brain itself.

Available Treatments

The treatment of a brain tumor depends on:

  • the type of tumor and where it is found
  • the size and shape of the tumor
  • your overall health

The most common treatment for a malignant brain tumor is a surgical procedure. The aim is to remove as much of the tumor as possible without causing damage to the healthy parts of the brain. The location of some tumors make for easy and safe removal, other tumors can be in an area that makes this very difficult. Even if they can only get to some of the cancerous cells it can have many benefits for the sufferor.

As with any surgery there are risks involved, these include infections and bleeding. Benign tumors are also removed surgically. Metastatic brain tumors are treated according to guidelines for the type of original cancer.

Surgery can also be combined with other treatments, such as chemo and radiation therapy.


The outlook for a brain tumor will depend on:

  • the type and size of the tumor
  • Where it’s located
  • your overall health

Early treatment can change your chance of survival drastically and also prevent complications that could occur as the tumor grows and puts pressure on the brain tissue as well as your skull. Please visit a doctor if you are worried about any of the above symptoms.

My Final Thoughts

Brain Tumors are a very dangerous thing to have, the quicker they are diagnosed the better the outcome for the patient.

You are more likely to get a brain tumor the older you become. It’s possible to be diagnosed as early as in your 20’s. Brain tumors are most commonly found in Caucasians. Speak to a doctor if people in your family have been diagnosed.

Take great care of yourself because you are worth it.

  1. Wow. I did not know there where so many different types of brain tumors.It was almost painful reading through the different types! Do you need to have all or most of the symptoms to get diagnosed? Or just a couple? I am wondering if you could get an MRI just for a wellness check up. 

    • Thank you very much for the comments. To answer your questions. No you don’t need to have all of the symptoms to get diagnosed. I don’t think you could get an MRI wellness check unless you paid for it.


  2. Hello there, The exact cause of brain cancer is unknown. However, factors that can increase your risk of brain cancer include exposure to high doses of ionizing radiation and a family history of brain cancer. Cancer in another part of your body is also a risk factor.Thanks anyway for sharing this awesome article.

    • Thank you very much for the comment.

      Brain tumors are very dangerous and one minute you can be okay and the next you can be in serious trouble. Take the symptoms seriously.
