What Are The Types Of Brain Tumors

Sex differences identified in deadly brain tumors

Doctors classify brain and central nervous system tumors based on where they form and the kind of cells they involve.

Brain tumors that are usually benign include:

  • Acoustic neuroma:These tumors occur on the vestibular nerve . Acoustic neuromas are also called vestibular schwannomas.
  • Gangliocytoma: These central nervous system tumors form in neurons .
  • Meningioma:These are the most common type of primary brain tumors. Meningiomas develop slowly. They form in the meninges, the layers of tissue that protect the brain and spinal cord. In rare cases, a meningioma can be malignant.
  • Pineocytoma: These slow-growing tumors form in the pineal gland, which is located deep in the brain and secretes the hormone melatonin.
  • Pituitary adenoma: These tumors form in the pituitary gland, which is located at the base of the brain. The pituitary gland makes and controls hormones in the body. Pituitary adenomas are usually very small.
  • Chordoma: These slow-growing tumors typically begin at the base of the skull and the bottom part of the spine. They are mostly benign .

Cancerous brain tumors include:

  • Glioma:These tumors develop in glial cells, which surround and assist nerve cells. Two-thirds of cancerous primary brain tumors are gliomas. Types of gliomas include:
  • Astrocytoma: Astrocytomas form in glial cells called astrocytes.
  • Glioblastoma: Aggressive astrocytomas that grow quickly are glioblastomas.
  • Oligodendroglioma: These uncommon tumors begin in cells that create myelin .

What Are The Signs And Symptoms Of Glioma

Glioblastomas can often have similar symptoms to other gliomas. The symptoms can vary depending on the location and size of the tumor. The symptoms can worsen over time as the tumor grows and invades other surrounding structures.

Common signs and symptoms of gliomas include:

  • A decline in the brain function
  • Memory problems

Most Meningiomas Do Not Spread

It can be shocking for someone to be diagnosed with a meningioma especially a large one but these tumors are usually benign. This means that the tumor cells are not likely to spread to other parts of the body.

That said, meningiomas can quietly grow for years without causing any problems and they can get surprisingly large.

Primary Vs Metastatic Brain Tumors

Primary brain tumors are tumors that start in the brain. Examples of tumors that most often originate in the brain include meningioma and glioma. Very rarely, these tumors can break away and spread to other parts of the brain and spinal cord. More commonly, tumors spread to the brain from other parts of the body.

Metastatic brain tumors, also called secondary brain tumors, are malignant tumors that originate as cancer elsewhere in the body and then metastasize to the brain. Metastatic brain tumors are about four times more common than primary brain tumors. They can grow rapidly, crowding or invading nearby brain tissue.

Common cancers that can spread to the brain are:

What Screening Tests Are Available

Hope for a deadly form of brain cancer

Primary brain tumors are rare and are not screened for with any specific tests. The best way to find a brain tumor early is to see your health care provider regularly for a thorough physical examination and to report any new, worrisome symptoms as soon as possible. People with genetic disorders that predispose them for the development of primary brain tumors will often have periodic imaging studies of their brains to look for any changes to their brain.

Other Primary Brain Tumors

Other primary brain tumors include:

  • pituitary tumors, which are usually benign
  • pineal gland tumors, which can be benign or malignant
  • ependymomas, which are usually benign
  • craniopharyngiomas, which occur mostly in children and are benign but can have clinical symptoms like changes in vision and premature puberty
  • primary central nervous system lymphomas, which are malignant
  • primary germ cell tumors of the brain, which can be benign or malignant
  • meningiomas, which originate in the meninges
  • schwannomas, which originate in cells that produce the protective cover of your nerves called Schwann cells

Most meningiomas and schwannomas occur in people between the ages of 40 and 70. Meningiomas are more common in women than men. Schwannomas occur equally in both men and women. These tumors are usually benign, but they can cause complications because of their size and location. Cancerous meningiomas and schwannomas are rare but can be very aggressive.

Meningiomas Can Grow In Different Places

These tumors arise from cells in the meninges, the lining of the brain and spinal cord. So technically speaking, theyre not brain tumors at all since they dont result from mutated brain cells.

But they still grow inside your skull, which means theres cause for concern. If a meningioma grows or causes swelling that presses against the brain or other structures in the skull, it can cause brain tumor symptoms.

Potential origin sites for meningioma in the brain:

Types Of Brain Cancer

Astrocytomas, which are the most common CNS tumor, arise anywhere in the brain or spinal cord, and develop from small, star-shaped cells called astrocytes. In adults, astrocytomas most often occur in the cerebrum, the largest part of the brain. The cerebrum uses sensory information to tell us whats going on around us and how the body should respond. The cerebrum also controls speech, movement and emotions, as well as reading, thinking and learning.

Brain stem gliomas are a type of astrocytoma that forms in the brain stem, which controls many vital functions, such as body temperature, blood pressure, breathing, hunger and thirst. The brain stem also transmits all the signals to the body from the brain. The brain stem is in the lowest part of the brain and connects the brain and spinal cord. Tumors in this area can be difficult to treat. Most brain stem gliomas are high-grade astrocytomas.

Glioblastoma multiforme, also known as glioblastoma, GBM or grade 4 astrocytoma, is a fast-growing, aggressive type of CNS tumor that forms on the supportive tissue of the brain. Glioblastoma is the most common grade 4 brain cancer. Glioblastomas may appear in any lobe of the brain, but they develop more commonly in the frontal and temporal lobes. Glioblastomas usually affect adults.

Aside from astrocytomas, there are a number of different primary brain tumors and other nervous system tumors that form from glial cells. They include:

Why Brain Tumors Arent Always A Death Sentence

More than 700,000 Americans are living with brain tumors. Here are five steps to take you from diagnosis to cure.

5 min read

While brain tumors have the potential to be as serious a condition as you can experience, the reality is that most patients who receive that diagnosis wont be blindsided by the news. Thats because most brain tumor patients tend to become symptomatic leading up to diagnosis, meaning that theyll begin to experience symptoms like headaches, personality changes, and even seizures. If you are diagnosed, dont fearmore than 700,000 Americans are currently living with a brain tumor, a diagnosis that, in most cases, is not considered a death sentence.

If you or your loved one are among the 700,000, heres what you should do.

Questions To Ask Before Treatment

Team

The following questions provide a starting point for what you may want to ask your healthcare professional.

    Fatal Brain Tumors On The Rise In England

    • Fatal Brain Tumors on the Rise in England
    • 26 MAR 18

    From Louis Slesin, Microwave NewsRate of GBM More than Doubled Between 1995 and 2015

    Excerpt

    The incidence of glioblastoma multiforme , the deadliest type of brain tumor, more than doubled in England between 1995 and 2015, according to a new analysis of national statistics. During that time, the number of cases of GBM rose from 983 to 2,531.

    We found a sustained and highly significant increase in GBM throughout the 21 years and across all ages, said Alasdair Philips, the lead author of the study, which has just been released online by the peer-reviewed, open access, Journal of Environmental and Public Health.

    The incidence rate of GBM, the most aggressive and quickly fatal brain tumor, is rising dramatically in England while the rates for lower grade tumors have decreased, masking this dramatic trend in the overall data, Philips told us from his home in southern Scotland.

    Its not known whats responsible for the change, but one possibility is the widespread use of cell phones.

    A similar trend has not been seen in the U.S.

    How Common Are Brain Tumors And Are They Dangerous

    In the United States, brain and nervous system tumors affect about 30 adults out of 100,000. Brain tumors are dangerous because they can put pressure on healthy parts of the brain or spread into those areas. Some brain tumors can also be cancerous or become cancerous. They can cause problems if they block the flow of fluid around the brain, which can lead to an increase in pressure inside the skull. Some types of tumors can spread through the spinal fluid to distant areas of the brain or the spine.

    Is Glioblastoma Always Fatal

  • Is Glioblastoma Always Fatal? Center
  • Glioma is a broad term used to describe the different types of glial tumors, which are astrocytoma, oligodendroglioma, and glioblastoma. Gliomas are the commonest type of tumors that originate in the brain. Glioma is a type of brain tumor that arises from glial cells in the brain and spinal cord. Glial cells are cells with supply the nerve cells with nutrients and help maintain the blood-brain barrier. There are different types of glial cells, and each has a different function. These are called astrocyte, oligodendrocyte, microglia, and ependymal cells.

    Gliomas vary in their aggressiveness. Some are slow-growing and are highly curable whereas others are fast-growing, invasive, difficult to treat, and with a high recurrence rate and poor prognosis. Glioma can affect brain function and be life-threatening depending on its location and rate of growth.

    Glioblastoma is also called glioblastoma multiforme. It is an extremely aggressive, fast growing type of cancer arising from the astrocytes in the brain or spinal cord. Glioblastoma can occur at any age but is more common in older adults. It is characterized by worsening headaches, nausea, vomiting, and seizures. Glioblastoma rarely spreads from the brain to other parts of the body but aggressively invades and spreads within the brain.

    Survival Rates For Selected Adult Brain And Spinal Cord Tumors

    A patient survives a fatal Brain Tumor after adopting a Ketogenic Diet.

    Survival rates can give you an idea of what percentage of people with the same type of brain or spinal cord tumor are still alive a certain amount of time after they were diagnosed. They cant tell you how long you will live, but they may help give you a better understanding of how likely it is that your treatment will be successful.

    Keep in mind that survival rates are estimates and are often based on previous outcomes of large numbers of people who had a specific type of tumor, but they cant predict what will happen in any particular persons case. These statistics can be confusing and may lead you to have more questions. Talk with your doctor about how these numbers may apply to you, as he or she is familiar with your situation.

    Types Of Brain And Spinal Cord Tumors In Adults

    There are two main types of brain and spinal cord tumors:

    • Tumors that start in the brain or spinal cord are called primary brain tumors.
    • Tumors that start in another part of the body and then spread to the brain or spinal cord are called metastatic or secondary brain tumors.

    In adults, metastatic tumors to the brain are actually more common than primary brain tumors, and they are treated differently. This information is about primary brain tumors.

    Unlike cancers that start in other parts of the body, tumors that start in the brain or spinal cord rarely spread to distant organs. Even so, brain or spinal cord tumors are rarely considered benign . They can still cause damage by growing and spreading into nearby areas, where they can destroy normal brain tissue. And unless they are completely removed or destroyed, most brain or spinal cord tumors will continue to grow and eventually be life-threatening.

    Diagnosis Of Brain Cancer

    If a brain tumour is suspected, the doctor may check how different parts of the brain are functioning by checking your reflexes, muscle strength, balance and coordination, ability to feel pin-pricks and to distinguish between hot and cold. An opthalmoscope is used to view the optic nerve, which may bulge if the pressure in the skull is raised, for example by a tumour.

    The main tests for brain cancer diagnosis are:

    Primary Brain Cancer Is Rare

    A primary malignant brain tumor is a rare type of cancer accounting for only about 1.4% of all new cancer cases in the U.S. The most common brain tumors are known as secondary tumors, meaning they have metastasized, or spread, to the brain from other parts of the body such as the lungs, breasts, colon or prostate.

    What To Know About Benign Tumors

    Not All Brain Tumours Are Cancerous And Fatal, Says A Study

    The most common types of benign brain tumors are:

    • Meningiomas: Meningiomas are common and originate in the central nervous system, which contains the brain and spinal cord. Though benign, they create serious symptoms, including headaches, speech problems and seizures, and they can even become fatal if untreated.
    • Acoustic neuromas: Acoustic neuromas develop on the nerves that lead from the ear to the brain and can interfere with balance and normal facial muscle movement.
    • Pituitary: Pituitary tumors form on the vital pituitary gland and disrupt the hormones responsible for essential bodily functions.

    A Brain Tumor Is A Mass Or Lump In The Brain Which Is Caused When Brain Cells Divide And Grow In An Uncontrolled Way

    The two main groups of brain tumors are termed primary and metastatic

    Malignant brain tumours can be identified as Brain cancer. They can be divided into low-grade brain cancer and high-grade cancers. Brain cancer can spread to other parts of the brain or the spine but rarely spreads to other parts of the body. If cancerous cells develop elsewhere in the body first and then spread to the brain, this is called secondary brain cancer or brain metastasis. Brain tumours also include both benign brain diseases as well as brain cancers.

    According to a report published by the National Health Portal of India, the incidence of central nervous system tumours in India ranges from 5 to 10 per 100,000 populations with an increasing trend. Metastatic brain tumours occur when cancer located in another organ of the body spreads to the brain. 40% of all cancers spread to the brain. Brain and CNS tumours are also the second most common cancers in children, accounting for about 26% of childhood cancers.
