According to the National Brain Tumor Society, there are more than 120 different forms of brain tumors. Glioblastoma multiforme, for example, is a malignant brain tumor that can grow quickly. Other brain tumors, such as a meningioma, may grow slowly and be benign.
Primary brain tumours occur in brain cells and are classified according to the type of cell or the location in the brain where they first appear. Astrocytomas, for example, develop in astrocytes, which are star-shaped cells.
Pituitary tumours develop in the pituitary gland, located at the brain’s base. Gliomas are the most frequent primary brain tumours, and they arise from the glial (supporting) tissue. Glial cells are responsible for around a third of all primary brain tumours and other nervous system malignancies.
Not all forms of brain tumors are cancerous; few of them can be benign. Irrespective of the tumors, it needs to be removed. There are various types of brain tumors that can affect the brain; the most common ones include,
Astrocytomas are the most common central nervous system tumour type that develops from small, star-shaped cells called astrocytes and can occur anywhere in the brain or spinal cord. However, astrocytomas most commonly occur in the cerebrum, the most significant portion of the brain, in adults.
Gliomas of the brain stem are astrocytoma that develops in the part of the brain that governs several critical activities, including body temperature, blood pressure, respiration, appetite, and thirst. Tumors in this region are notoriously challenging to treat. The majority of gliomas in the brain stem are high-grade astrocytomas. Consult with a doctor at the best hospital for brain tumor.
Glioblastoma multiforme: Glioblastoma, also known as GBM or grade 4 astrocytomas, is a fast-growing, aggressive type of brain tumour that develops on the brain’s supporting tissue. Glioblastoma is the most common type of grade 4 brain cancer.
Glioblastomas can develop in any lobe of the brain, but they are more common in the frontal and temporal lobes. Glioblastomas are more typically found in adults.
Meningioma: forms in the membrane cells that encircle the brain and spinal cord. Meningiomas (also known as meningeal tumours) make up around a quarter of all intracranial tumours. The majority of these tumours are harmless (non-cancerous and slow-growing). Brain tumor removal surgery is usually used to remove meningiomas.
Apart from astrocytomas, there are various types of primary brain tumors that include:
Ependymomas are most commonly seen in the lining of the ventricles and gaps in the brain and around the spinal cord. Ependymomas can affect people of any age. Ependymomas are another type of spinal tumour.
Oligodendrogliomas develop in myelin-producing cells in the brain, and spinal cord, the fatty covering that protects nerves. These tumours are highly uncommon and mainly develop in the cerebrum. They grow slowly and rarely disseminate into the surrounding brain tissue.
There are two types of tumour cells in mixed gliomas: oligodendrocytes and astrocytes. The cerebrum is the most common location for this type of brain tumour.
Other different types of brain tumors include,
Craniopharyngiomas originate near the pituitary gland (the main endocrine gland that generates hormones that control other glands and many body processes, particularly growth) in the brain’s hypothalamus region. Most types of these tumours are benign.
They are, however, sometimes classified as malignant because they might put pressure on or harm the hypothalamus, impairing critical activities. Children, teenagers, and adults over the age of 50 are the most common victims of these tumours.
Germ cell tumors are germ cells derived from developing sex (egg or sperm) cells. The germinoma is the most prevalent kind of germ cell tumour in the brain. Germinomas can develop in the ovaries, testicles, chest, belly, and brain. Book your appointment with a brain tumor specialist for the treatment.
Pineal region tumors happen in or around the pineal gland, a tiny organ in the brain’s core. Melatonin is a hormone produced by the pineal gland that plays a crucial part in the sleep-wake cycle. These brain cancer tumours can grow slowly (pineocytoma) or quickly (astrocytoma) (pineoblastoma).
Medulloblastomas are fast-growing brain tumours that arise from the cerebellum’s neurons. The cerebellum is located at the back of the brain and is responsible for movement, balance, and posture. Children and young people are the most common victims of these malignancies.
Pituitary Adenoma, the most frequent type of pituitary tumour, is an adenoma, which is a type of tumour that grows in gland tissues. Pituitary adenomas are slow-spreading tumours that arise from the pituitary gland. Adenomas account for about 10% of all primary brain tumours. They are responsible for inducing eyesight and endocrinological troubles. Consult the top hospitals in Coimbatore for advanced treatment and cancer care.
Craniopharyngioma these benign tumours can look like solid tumours or cysts and grow around the pituitary gland. Around the pituitary gland, craniopharyngiomas commonly push on nerves, blood vessels, or sections of the brain. They, like adenomas, can cause vision and endocrinological problems.
Schwannoma acoustic neuromas (vestibular schwannomas) are benign nerve tumors from the ear to the brain that grow slowly. Acoustic neuromas make up less than 8% of all other primary brain tumours. They typically appear in middle-aged individuals, grow on the nerve sheath (the coating that surrounds the nerve fibres), and frequently result in hearing loss.
Nasopharyngeal Angiofibroma Nasopharyngeal angiofibroma, also known as juvenile nasopharyngeal angiofibroma, is a benign nasal skull base tumor that is most commonly found in adolescent boys.
Choroid Plexus Tumor is a rare tumor that develops in the choroid plexus, the brain region that creates cerebrospinal fluid within the ventricles. Approximately 90% of these tumours are benign.
Dysembryoplastic Neuroepithelial Tumor This is a form of a neuronal-glial brain tumour in which neurons and supporting cells are mixed. Dysembryoplastic neuroepithelial tumours are benign tumours that develop in the tissues that surround the brain and spinal cord.
Neurofibroma are benign tumours that form on nerves throughout the body and are usually painless. However, in some situations, these soft, fleshy growths can appear in the brain, on cranial nerves, or in the spinal cord. A famous neurosurgeon in Coimbatore will assist a patient in determining the best course of treatment.
Each type of brain tumor causes different kinds of symptoms, and also diagnosis depends on the signs.
Brain cancer comes in a variety of forms. Astrocytoma is the most frequent type of glioma, which can progress to glioblastoma multiforme in extreme situations. GBM is a very aggressive and fast-growing cancer. There are a variety of brain cancer treatments available.
