Do you know about the different types of a brain tumour?

Also known as intracranial tumours, brain tumours are abnormal masses of unhealthy cells and tissues that have grown uncontrollably and accumulated to form a lump. Experts from the best hospital in Madhya Pradesh suggest that there are over 150 types of brain tumours, that are majorly categorised under two groups - primary brain tumours and metastatic brain tumours.

Primary brain tumours refer to those brain tumours that originate in the brain itself. These may also develop in the area surrounding the brain. These are further categorised as glial brain tumours and non-glial brain tumours. The former, as the name suggests, originates from the glial cells, whereas the latter originates from the various structures present in the brain (nerves, blood vessels and glands).

Metastatic brain tumours refer to those tumours that develop in different organs of the body and migrate to the brain by invading the bloodstream. As these do not originate in the brain itself, they are also referred to as secondary tumours.

In this blog, we have shed light on some common types of brain tumours with the help of the best brain tumour surgeon in Indore.

Benign brain tumours –

Chordomas - These grow at a very slow pace and are much more common in adults lying in the age group of 50 to 60 years. These usually develop at the skull base or originate from the lower part of the spine. Despite being benign, the tumour can spread to the surrounding bone structures and may also put an unnecessary strain on the neural tissue. Chordomas are quite rare and makeup only 0.2 per cent of all primary brain tumours.

Craniopharyngiomas - Although the tumours are benign, they can be quite hard to treat, owing to their critical location. They originate from the pituitary gland and lie deep within the brain. This makes them quite difficult to extract or remove. Patients suffering from craniopharyngiomas usually require hormone replacement therapy.

Gangliocytomas - These, along with gangliomas and anaplastic gangliogliomas, form an extremely rare category of cancers, that involve the neoplastic Nerve cells. The cells are very well differentiated and predominantly found in young adults.

Glomus jugulare - These are located between the skull base and the jugular vein. Glomus jugulare happens to be the most common type of glomus tumour, contributing to only 0.6 per cent of head and neck neoplasms.

Meningiomas - Accounting for nearly 10 to 15 per cent of all brain neoplasms, meningiomas happen to be the most common type of benign brain tumours. As the name suggests, these originate from the meninges, the membrane that surrounds the brain.

Pituitary adenomas - Adenoma happens to be one of the most common diseases affecting the pituitary gland. These are listed amongst the most common intracranial tumours, including gliomas, meningiomas and schwannomas. Though pituitary adenomas can affect both adults as well as children, these are quite common in people lying in the age group of 30 to 40 year.

Schwannomas - These are quite aggressive in nature and usually affect adults. In the majority of the cases, the malignancy does not invade the nerve cell but only displaces its remainder. These may also develop in the spine.

Types of malignant brain tumours –

Astrocytomas - Accounting for nearly 50% of all primary brain tumours, these are the most common type of gliomas. Although astrocytomas can develop in any part of the brain, they are much more likely to develop in the cerebrum. With a higher prevalence in adults, these tumours are very common in middle-aged men. It is however pertinent to note that astrocytomas that develop in the base of the brain are more common in children.

Ependymomas - Accounting for around 2 to 3 per cent of all brain tumours, ependymomas are a result of neoplastic transformation of ependymal cells that line the ventricular system.

Glioblastoma multiforme - Commonly referred to as GBM, these are highly aggressive and invasive in nature. This progresses at a very fast pace and is quite difficult to treat. Such tumours are predominantly found in men lying in the age group of 50 to 70 years
