Brain Tumor- Types, symptoms, and causes

20 January, 2022 Anuja Sahi

A brain tumour could be a mass or growth of abnormal cells in your brain.

Many different varieties of brain tumors exist. Some brain tumors area unit noncancerous (benign), and a few brain tumors area unit cancerous (malignant), thus some brain tumors are cancerous while others are non-cancerous. Brain tumors will begin in your brain (primary brain tumors), or can begin in different elements of your body and unfold to your brain as secondary (metastatic) brain tumors.

What is a brain tumor?

A brain tumor could be an assortment, or mass, of abnormal cells in your brain. Your skull, that encloses your brain, is extremely rigid. Any growth within such a restricted area will cause issues. Brain tumors are often cancerous (malignant) or noncancerous (benign). Once benign or malignant tumors grow, they will cause the pressure within your bone to extend. This may cause brain harm, and it are often dangerous.

Types of brain tumor

  • Primary Brain Tumor
  • Gliomas

Primary brain tumor

Primary brain tumors originate in your brain. They will develop either from your:

  • Brain cells
  • The membranes that surround your brain, that square measure referred to as tissue
  • layer
  • Nerve cells
  • Glands

Primary tumors are either benign or cancerous. In adults, the foremost common sorts of brain tumors square measure Gliomas and meningioma.


Gliomas square measure tumors that develop from interstitial tissue cells. These cells normally:

  • Support the structure of your central systema nervosum
  • Provide nutrition to your central systema nervosum
  • Clean cellular waste
  • Break down dead neurons
  • Gliomas will develop from differing types of interstitial tissue cells.

The types of tumors that begin in interstitial tissue cells are:

Astrocytic tumors like astrocytomas that originate within the neural structure Oligodendroglial tumors, that square measure typically found within the frontal temporal lobes Glioblastomas that originate within the ancillary brain tissue and square measure the foremost aggressive kind

Types of Benign Brain Tumors

  • Chordomas are unit benign, slow-growing tumors that are unit most prevailing in individuals’ ages fifty to sixty. Their commonest locations area unit the bottom of the bone and also the lower portion of the spine. Though these tumors area unit benign, they'll invade the adjacent bone and place pressure on near neural tissue. These area unit rare tumors, tributary to solely zero.2 % of all primary brain tumors.
  • Craniopharyngiomas generally are benign; however are tough tumors to get rid of as a result of their location close to important structures deep within the brain. They sometimes arise from some of the pituitary (the structure that regulates several hormones within the body), therefore nearly all patients would force some secretion replacement medical care.
  • Glomus jugulare tumors most often are benign and usually are situated just below the skull base, at the highest of the vena. They're the foremost common type of glomus neoplasm. However, glomus tumors, in general, contribute to solely zero.6 p.c of neoplasms of the top and neck.
  • Pituitary adenomas are the foremost common intracranial tumors when gliomas, meningiomas and schwannomas. The massive majority of pituitary adenomas ar benign and fairly slow-growing. Even malignant pituitary tumors seldom unfold to different elements of the body. Adenomas are out and away the foremost common sickness poignant the pituitary. They normally have an effect on folks in their 30s or 40s, though they're diagnosed in youngsters, as well. Most of those tumors may be treated with success.

Symptoms of brain tumors

  • Persistent headaches
  • Problems with vision
  • Nausea, vomiting, and general sleepiness
  • Seizures
  • Issues with short term memory
  • Speech issues
  • Coordination problems
  • Personality changes

The symptoms of a brain tumorrely on tumor size, type, and site. Symptoms could also be caused once a growth presses on a nerve or harms a locality of the brain. Also, they'll be caused once a growth blocks the fluid that flows through and round the brain, or once the brain swells due to the buildup of fluid.


Brain tumors will have an effect on brain functioning ability if they grow giant enough to go on close nerves, blood vessels and tissue. Your outcome is set by such factors because the tumor’s sort, grade, and location; the success of neoplasm removal; and your age and overall health.
