A benign brain tumor is a mass of tissue that grows and multiplies abnormally. Benign brain tumors are noncancerous, which means they will not spread to other regions of the body and will not infect surrounding tissue.

Non-cancerous brain tumors often remain in one area and do not spread. If the entire tumor is removed safely during surgery, it is unlikely to return.

But if the tumor is not entirely removed, it would have the possibility to recur. In this case, it will be constantly monitored by scans and maybe treated with radiotherapy. 95% of benign brain tumors are discovered with CT or MRI brain scans. The most frequent benign brain tumors are meningioma and schwannoma. Let’s know about the types of Benign Brain Tumor are-

Types of Benign Brain Tumors that you must Know

Brain tumors are usually harmless. The following are Types of benign brain tumors:

Cordomas

Chordoma is a rare type of cancer that attacks the bones near the base of the head and the spine. It belongs to the sarcoma category of malignant bone and soft tissue cancers. Although it can occur at any age, chordoma most frequently affects individuals between the age of 40 and 60.

The leftover cells that were essential for the development of the spine before birth give rise to chordomas. They are known as notochord cells. The notochord cells can develop into chordomas if they remain after delivery.

Typically, chordoma grows slowly. Due to its constant proximity to the spinal cord and other vital systems including arteries, nerves, or the brain, it can be challenging to cure. Source

Meningioma

A meningioma is a tumor that develops from the membranes that surround the brain and spinal cord, known as the meninges. Although not strictly a brain tumor, it is classified as such since it has the potential to compress or pressure the nearby brain, nerves, and arteries.

Meningiomas develop from the arachnoid layer of the meninges, which is the intermediate layer of the meninges. They grow slowly and can live for years before being discovered. A meningioma may be detected by chance during a head or spinal cord magnetic resonance imaging (MRI) scan. 

Meningioma symptoms might be minor at first and gradually worsen as the tumor grows and presses on the brain or spinal cord.

Gangliocytomas

Gangliocytoma is a rare kind of tumor of the central nervous system (CNS) composed of mature neurons. They are among the most common malignancies linked to epilepsy. Gangliocytomas can arise at any age, however, they are most common in adults between the ages of 10 and 30. The temporal lobe of the brain is the most common area, but it can also occur in the cerebellum, brainstem, third ventricle floor, and spinal cord, among other parts of the central nervous system (CNS).

Depending on where the tumor lies, signs and symptoms may include seizures (which occur most frequently), increased brain pressure, endocrine abnormalities, and localized symptoms. In general, gangliocytomas grow slowly and rarely develop into cancer. Source

Craniopharyngiomas

Craniopharyngiomas are benign tumors that develop near the pituitary gland in the brain, which secretes hormones that regulate numerous bodily activities. They might manifest as solid tumors or cysts (hollow sacs filled with fluid).

Craniopharyngiomas are slow-growing tumors that do not spread to other areas of the brain or the body. They may, however, develop and press on surrounding brain structures such as the pituitary gland, hypothalamus, optic chiasm, optic nerves, and fluid-filled areas. This can lead to issues with growth, eyesight, and the production of certain hormones. Craniopharyngiomas are more common in children and young adults.

Pineocytomas

A pineocytoma is a tumor of the pineal gland, a tiny organ in the brain responsible for the production of melatonin (a sleep-regulating hormone). Pineocytomas typically develop as a solid mass in adulthood, although scans of the brain may show fluid-filled (cystic) areas inside them.

Pineocytomas cause headaches, nausea, hydrocephalus, visual problems, and Parinaud syndrome. Pineocytomas grow slowly and seldom spread to other parts of the body. For optimal therapy, a team of experts is required. UCLA neurosurgery, neuropathology (microscopic diagnosis), radiation therapy, Source

Pituitary adenomas

Pituitary adenomas are benign tumors that form on the pituitary gland. They are not malignant, but they can disrupt normal pituitary function and cause certain health problems. This gland is a little organ about the size of a pea. It is at the base of the brain, behind the nose. The majority are found in the gland’s front lobe (front section).

It doesn’t spread to other sections of your body as cancer does. Pituitary adenomas, however, can impose pressure on surrounding structures as they expand and result in symptoms. Pituitary adenomas are treated by medical professionals using surgery, medicine, radiation therapy, or a combination of these treatments.  Source

Schwannomas

A Schwannoma is a peripheral nervous system or nerve root tumor. Schwannomas form from Schwann cells, a type of cell that wraps around peripheral nerves and provides protection and support. Schwannomas are most commonly found in the nerve that links your brain to your inner ear (vestibular schwannoma).

Schwannomas are usually benign (non-cancerous), but they can sometimes become cancerous (a malignant Schwannoma). Symptoms of a Schwannoma can be nonspecific and vary according to its extent and size, but they may include a visible or felt lump or bulge, pain, muscle weakness, tingling, numbness, hearing issues, and/or facial paralysis. Schwannomas can sometimes go unnoticed. Source

Glomus jugulare

Glomus jugulare tumors are rare, slow-growing, hypervascular tumors that develop within the temporal bone’s jugular foramen and frequently affect the lower cranial nerves. Glomus jugular tumors develop from glomus cells in the jugular bulb’s outermost wall.

These tumors are usually benign, or noncancerous, but their existence might result in hearing loss, swallowing difficulties, and facial paralysis. Imaging tests and a biopsy can be used by your doctor to confirm the presence of a glomus jugular tumor. Source
