Meningiomas Can Grow In Different Places

Tony’s Story: Eliminating a Complex Brain Tumor

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:

What Is Radiation Treatment For Brain Tumors

Radiation therapy kills brain tumor cells with high-energy x-rays, gamma rays, or protons.

Radiation therapy usually follows surgery. The radiation kills tumor cells that may remain in the area. Sometimes, people who can’t have surgery have radiation therapy instead.

Doctors use external and internal types of radiation therapy to treat brain tumors:

  • Internal radiation therapy : Internal radiation isn’t commonly used for treating brain tumors and is under study. The radiation comes from radioactive material usually contained in very small implants called seeds. The seeds are placed inside the brain and give off radiation for months. They don’t need to be removed once the radiation is gone.
  • Some people have no or few side effects after treatment. Rarely, people may have nausea for several hours after external radiation therapy. The health care team can suggest ways to help you cope with this problem. Radiation therapy also may cause you to become very tired with each radiation treatment. Resting is important, but doctors usually advise people to try to stay as active as they can.

    Also, external radiation therapy commonly causes hair loss from the part of the head that was treated. Hair usually grows back within a few months. Radiation therapy also may make the skin on the scalp and ears red, dry, and tender. The health care team can suggest ways to relieve these problems.

    Laser Interstitial Thermal Therapy

    Laser Thermal Ablation is a newer technique that some centers are using to treat smaller tumors particularly in areas that may be more difficult to reach using previous open surgery procedures. This involves placing a tiny catheter within the lesion, possibly completing a biopsy, then using laser to thermally ablate the lesion. This technique is only more recently used in brain tumor treatments, therefore the long term efficacy has not been established.

    Types of Malignant Brain Tumors

    Gliomas are the most prevalent type of adult brain tumor, accounting for 78 percent of malignant brain tumors. They arise from the supporting cells of the brain, called the glia. These cells are subdivided into astrocytes, ependymal cells and oligodendroglial cells . Glial tumors include the following:

    Meningioma Treatment: Surgery Or Not

    Sometimes, believe it or not, your doctor may recommend observation for meningioma, especially if its small and not causing problems. Youll have regular MRIs to check on it.

    Otherwise, the main treatment for meningiomas is surgery to remove it, through a craniotomy or other procedure. Your doctor will go over what the operation will involve, the approach to access the tumor and what you can expect afterward.

    How does a neurosurgeon operate on a meningioma? Its all about location. Depending on where the tumor is, each approach will be different. Tumors close to the surface are typically easier to access than those located along the skull base.

    Skull base tumors are those located deep in the skull, behind the nose or eyes. These can be challenging, and call for surgeons with skill and expertise in this kind of surgery.

    There are a number of new techniques in brain tumor surgery, even for tumors located deep in the skull, and some of these are less invasive.

    One system involves a camera-assisted tube that gently moves brain tissue aside so surgeons can reach the tumor with less cutting, so patients can recover faster,

    After your treatment you will have regular MRIs to ensure the tumor isnt returning.

    In many cases, it wont. After 10 years, about 90 percent of patients who have had a meningioma have not seen a recurrence if the tumor is removed completely, including the part of the brain lining from which it grew.

    Types Of Cells And Body Tissues In The Brain And Spinal Cord

    The brain and spinal cord have many kinds of tissues and cells, which can develop into different types of tumors.

    Neurons : These are the cells in the brain that help determine thought, memory, emotion, speech, muscle movement, sensation, and just about everything else that the brain and spinal cord do.

    Unlike many other types of cells that can grow and divide to repair damage from injury or disease, neurons in the brain and spinal cord largely stop dividing about a year after birth . Neurons do not usually form tumors, but they are often damaged by tumors that start nearby.

    Glial cells: Glial cells are the supporting cells of the brain. Most brain and spinal cord tumors develop from glial cells. These tumors are sometimes referred to as gliomas.

    There are 3 main types of glial cells:

    • Astrocytes help support and nourish neurons. When the brain is injured, astrocytes form scar tissue that helps repair the damage. The main tumors starting in these cells are called astrocytomas or glioblastomas.
    • Oligodendrocytes make myelin, a fatty substance that surrounds and insulates the nerve cell axons of the brain and spinal cord. This helps neurons send electric signals through the axons. Tumors starting in these cells are called oligodendrogliomas.
    • Ependymal cells line the ventricles within the brain and form part of the pathway through which CSF flows. Tumors starting in these cells are called ependymomas.

    What Are The Treatment Options For Atypical And Anaplastic Meningiomas

    The first treatment for a malignant meningioma is surgery, if possible. The goal of surgery is to obtain tissue to determine the tumor type and to remove as much tumor as possible without causing more symptoms for the person.

    Most people with atypical and anaplastic meningiomas receive further treatments. After surgery, radiation is often recommended to delay the return of grade II and III meningiomas. Treatments may also include chemotherapy, or clinical trials. Clinical trials, with new chemotherapy, targeted therapy, or immunotherapy drugs, may also be available and can be a possible treatment option. The role of chemotherapy or clinical trials after radiation therapy is unclear. Treatments are decided by the patients healthcare team based on the patients age, remaining tumor after surgery, tumor type, and tumor location.

    Occupational Exposure And Safe Handling

    How Mass Shootings Affect the Brain

    In the 1970s, antineoplastic drugs were identified as hazardous, and the has since then introduced the concept of after publishing a recommendation in 1983 regarding handling hazardous drugs. The adaptation of federal regulations came when the U.S. first released its guidelines in 1986 and then updated them in 1996, 1999, and, most recently, 2006.

    The has been conducting an assessment in the workplace since then regarding these drugs. Occupational exposure to antineoplastic drugs has been linked to multiple health effects, including infertility and possible carcinogenic effects. A few cases have been reported by the NIOSH alert report, such as one in which a female pharmacist was diagnosed with papillary transitional cell carcinoma. Twelve years before the pharmacist was diagnosed with the condition, she had worked for 20 months in a hospital where she was responsible for preparing multiple antineoplastic drugs. The pharmacist didn’t have any other risk factor for cancer, and therefore, her cancer was attributed to the exposure to the antineoplastic drugs, although a cause-and-effect relationship has not been established in the literature. Another case happened when a malfunction in biosafety cabinetry is believed to have exposed nursing personnel to antineoplastic drugs. Investigations revealed evidence of genotoxic biomarkers two and nine months after that exposure.

    An Adult Central Nervous System Tumor Is A Disease In Which Abnormal Cells Form In The Tissues Of The Brain And/or Spinal Cord

    There are many types of brain and spinal cordtumors. The tumors are formed by the abnormal growth of cells and may begin in different parts of the brain or spinal cord. Together, the brain and spinal cord make up the central nervous system .

    The tumors may be either benign or malignant :

    • Benign brain and spinal cord tumors grow and press on nearby areas of the brain. They rarely spread into other tissues and may recur .
    • Malignant brain and spinal cord tumors are likely to grow quickly and spread into other brain tissue.

    When a tumor grows into or presses on an area of the brain, it may stop that part of the brain from working the way it should. Both benign and malignant brain tumors cause signs and symptoms and need treatment.

    Brain and spinal cord tumors can occur in both adults and children. However, treatment for children may be different than treatment for adults.

    After A Diagnosis Of Brain Cancer

    After finding out you have brain cancer, you may feel shocked, upset, anxious or confused. These are normal responses. A diagnosis of brain cancer affects each person differently. For most it will be a difficult time, however some people manage to continue with their normal daily activities.

    Your specialist will arrange for a range of health professionals to plan your treatment. This will be based on several factors including the type, size, location and genetic make-up of the cancer as well as, your age and general health, the types of symptoms you have and your needs and preferences.

    What Are Black Spots On The Brain

    Black or dark spots can be detected when someone undergoes imaging test that can include CT scans and MRIs. These dark spots, which are abnormal tissue matter, are referred to as a brain lesion, according to Mayo Clinic. While there are many different causes for brain lesions, some may present no major issues and others can be serious.

    Some common causes of a brain lesion are medical issues, such as an injury, tumors that can be benign or malignant, infection, abscess, or a stroke, notes WebMD. These brain lesion types can be different sizes, ranging for very small to those that can occupy a larger space of the brain.

    Because there are so many different brain lesion types, symptoms can vary accordingly. However, there are some common signs associated with many of them, including headaches, memory issues, behavioral changes and possible seizures, states WebMD.

    Imaging tests are useful in diagnosing a brain lesion because it can show its size, but other tests are necessary, such as blood tests and a biopsy. In the case of a malignant brain tumor, grading of the tumor is important. Similarly, these tumors can spread to other locations, notes the National Cancer Institute.

    Doctors treat a brain lesion according to its type and the varying symptoms it presents. For example, depending on the specific type of malignant brain tumor, its size and location, it can require a combination of treatments that can include radiation, chemotherapy or surgery.

    How Are Brain Tumors Diagnosed

    Diagnosis of a brain tumor begins with a physical exam and a look at your medical history.

    The physical exam includes a very detailed neurological examination. Your doctor will conduct a test to see if your cranial nerves are intact. These are the nerves that originate in your brain.

    Your doctor will look inside your eyes with an ophthalmoscope, which is an instrument that shines a light through your pupils and onto your retinas. This allows your doctor to check how your pupils react to light. It also allows your doctor to look directly into your eyes to see if theres any swelling of the optic nerve. When pressure increases inside the skull, changes in the optic nerve can occur.

    The doctor may also evaluate your:

    • muscle strength
    • ability to do mathematical calculations

    Your doctor may order more tests after they finish the physical exam. These could include:

    Symptoms Of A Brain Tumour

    The symptoms of a brain tumour vary depending on the exact part of the brain affected.

    Common symptoms include:

    • persistently feeling sick , being sick and drowsiness
    • mental or behavioural changes, such as memory problems or changes in personality
    • progressive weakness or paralysis on one side of the body
    • vision or speech problems

    Sometimes you may not have any symptoms to begin with, or they may develop very slowly over time.

    Who Is Diagnosed With Atypical And Anaplastic Meningiomas

    Meningiomas are more common in females, but grades II and III occur more often in males. They are most common in black people, followed by white people, and then Asian-Pacific Islanders. The meningiomas tend to occur in people around 60 years old, with the risk increasing with age. An estimated 2,692 people are living with this tumor in the United States.

    Brain herniation due to tumors is treated with mannitol 25 to 100 g infused IV, a corticosteroid , and endotracheal intubation. Hyperventilation to a carbon dioxide partial pressure of 26 to 30 mm Hg can help decrease intracranial pressure temporarily in emergencies. Mass lesions should be surgically decompressed as soon as possible.

    Increased intracranial pressure due to tumors but without herniation can be treated with corticosteroids .

    Treatment of the brain tumor depends on pathology and location . Surgical excision should be used for diagnosis and symptom relief. It may cure benign tumors. For tumors infiltrating the brain parenchyma, treatment is multimodal. Radiation therapy is required, and chemotherapy appears to benefit some patients.

    Treatment of metastatic tumors includes radiation therapy and sometimes stereotactic radiosurgery. For patients with a single metastasis, surgical excision of the tumor before radiation therapy improves outcome.

    The Central Nervous System

    To understand brain and spinal cord tumors, it helps to know about the normal structure and function of the central nervous system , which is the medical name for the brain and spinal cord.

    The brain is the center of thought, feeling, memory, speech, vision, hearing, movement, breathing, and much more. The spinal cord and special nerves in the head called cranial nerves help carry messages between the brain and the rest of the body. These messages tell our muscles how to move, transmit information gathered by our senses, and help coordinate the functions of our internal organs.

    The brain is protected by the skull. Likewise, the spinal cord is protected by the bones of the spinal column.

    The brain and spinal cord are surrounded and cushioned by a special liquid, called cerebrospinal fluid . Cerebrospinal fluid is made by the choroid plexus, which is found in spaces within the brain called ventricles. The ventricles and the spaces around the brain and spinal cord are filled with CSF.

    Types Of Brain Tumors

    A brain tumor, known as an intracranial tumor, is an abnormal mass of tissue in which cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. More than 150 different brain tumors have been documented, but the two main groups of brain tumors are termed primary and metastatic.

    Primary brain tumors include tumors that originate from the tissues of the brain or the brain’s immediate surroundings. Primary tumors are categorized as glial or non-glial and benign or malignant.

    Metastatic brain tumors include tumors that arise elsewhere in the body and migrate to the brain, usually through the bloodstream. Metastatic tumors are considered cancer and are malignant.

    Metastatic tumors to the brain affect nearly one in four patients with cancer, or an estimated 150,000 people a year. Up to 40 percent of people with lung cancer will develop metastatic brain tumors. In the past, the outcome for patients diagnosed with these tumors was very poor, with typical survival rates of just several weeks. More sophisticated diagnostic tools, in addition to innovative surgical and radiation approaches, have helped survival rates expand up to years and also allowed for an improved quality of life for patients following diagnosis.
