Brain Tumor: Types, Risk Factors, and Diagnosis

Brain Tumor Risks Factor

  • 2021-06-11

A brain tumor is a collection, or mass, of abnormal cells in your brain. A primary brain tumor is a tumor that begins in the brain tissue.

Like other carcinoma diseases, brain cancer is a result of uncontrollable cell growth within our brain. However, you need not be scared as you hear about it. Such a disease can be both benign and malignant; thus, a prompt is a momentary need when your doctor suspects its existence. Malignant growths show more metastatic inclination; thus, these diseases are more threatening for our lives.

Brain tumor types

Depending on their originating place, cerebrum cancers are classified. For instance,


Carcinoma symptoms, when comes first into our cerebrum cells, are called primary sickness. Primary brain tumors can develop in:

  • Brain cells.
  • Meninges – these are membranes surrounding our decision-making cells.
  • Nerve cells.

Primary types can be both cancerous and non-cancerous.

The commonest primary brain tumors are:

  • Pituitary tumor.
  • Pineal gland growths.
  • Ependymomas.
  • Craniopharyngiomas
  • Lymphomas in our primary central nervous system. It is a fatal carcinoma form.


Gliomas are developments in glial cells. These cells carry out the following functions:

  • Supporting our central nervous system structure and providing nutrition as well.
  • Free your CNS by removing cellular wastes.
  • Putting the dead neurons into pieces.

Conditions generate in this zone include:

  • Astrocytoma, an astrocytic tumor that generates in your cerebrum.
  • Oligodendroglial tumors often formed into our frontal-temporal lobes.
  • Glioblastomas have their core within most of these supportive cerebrum tissues; it is the fiercest among these types of diseases.

Metastatic brain tumors

These are also called secondary disease types. These contribute to the majority of brain cancers. They are metastatic means your disease is caused by cancer developed into another body part.

Some of these transferable diseases include:

  • Skin cancer.
  • Lung tumor
  • Kidney growth
  • Cancerous originations into the breast.

Common Risk Factors

Though it is more prevalent among old-age people, numerous youths are also reported to have similar kinds of things. Hereditary factors are not much lagging behind, though.

  • Overall 5-10% of cerebrum cancer cases are reported to have been developed from parental genes. Disclose to your doctor if any of your family members or parental members have any previous history of such a disease.
  • Age plays a crucial role to cause this disease.  It induces faster spread-up too.
  • Young people, who are made to work under hazardous conditions like chemical exposure, are more prone to brain disease.
  • People who have previous exposure to ion radiation are soft targets for carcinoma in the brain. It is often prescribed to treat other cancerous forms.  Nuclear fallout may also cause the illness.

Problem diagnosis

Once your doctor suspects the ailment, he will order some diagnostic pattern for confirmation. The program starts with a neurological examination. It includes checking vision, audio balance, physical coordination, strengths, and reflexes.

  • Based on your neurological examination, h/she will order imaging tests of which magnetic resonance is most used. The specialized MRI scan components include functional MRI, perfusion MRI and magnetic resonance spectroscopy. With their results, your doctor will be able to evaluate the condition's growth and plan treatment.
  • Depending on your case, doctors may also recommend CT or PET scans. However, these tests could not produce desired results in these cases as they produce for other cancerous forms.

Therefore, consulting doctors would recommend their uses to dictate traces of other cancerous diseases.

Sophisticated laboratory tests over hind-brain tissue. It is a biopsy process conducted over tissues in those areas where other forms of diagnoses won’t work. The test helps in finding any malignancy in your brain carcinoma.

Final words

PET is a good lung cancer diagnosing. It can also dictate whether the disease has spread to your cerebrum cells. Therefore, it can help your doctor to produce a solid grounding for such a condition.
