Symptoms Based On Tumor Location

Do Brain Tumors Require Surgery?

Some symptoms can provide insights into where the tumor might be located within the brain.

  • Vision problems. Vision problems can be due to a tumor located in or around the pituitary gland, optic nerve, occipital lobe, or temporal lobe.
  • Speech, reading, and writing difficulties. These difficulties may be caused by a tumor near the temporal lobe or parietal lobe.
  • Hearing problems. These may be caused by a tumor near the cranial nerves or temporal lobe.
  • Swallowing problems. There may be a tumor near the cerebellum or in or near cranial nerves.
  • Trouble with movement in the hands, arms, feet, and legs, or difficulty walking. This could be caused by a tumor near the cerebellum, frontal lobe, or brainstem.
  • Balance issues. Balance issues may indicate a tumor near the cerebellum, brainstem, or the base of the brain.
  • Facial numbness, weakness, or pain. This may also occur with a tumor involving the brainstem.

What Are Brain Cancer Symptoms And Signs

  • fatigue, and
  • pins and needles sensations and/or reduced sensation of touch.

These symptoms can also occur in people who do not have brain cancer, and none of these symptoms alone or in combination can predict that a person has brain cancer. Cancer can occur in any part of the brain . Primary cerebral lymphoma can occur but is rare so are craniopharyngiomas that are derived from the pituitary gland. A few brain cancers may produce few or no symptoms .

Controlling Seizures In People With Brain Tumors

Whether a person with a brain tumor has had one or 100 seizure episodes, controlling and preventing seizure activity is an essential part of their treatment.

In most cases, the seizures themselves do not pose a great health risk environmental hazards are of greatest concern.

Seizures don’t discriminate and can occur at any time, leading to possible injury of the person seizing and to those around them. There is concern about people seizing during routine activities like driving or bathing. Plus, there is a heightened risk of head injury from falling during an episode.

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 Is The Most Common Type Of Surgery To Remove Brain Tumors

Brain Cancer Vaccine Could Boost Incurable Glioblastoma ...

    Surgery is the usual first treatment for most brain tumors. Before surgery begins, you may be given general anesthesia, and your scalp is shaved. You probably won’t need your entire head shaved.

    Questions should you ask your surgeon before having a brain tumor removed

    • Do you suggest surgery for me?
    • How will I feel after the operation?
    • What will you do for me if I have pain?
    • How long will I be in the hospital?
    • Will I have any long-term effects? Will my hair grow back? Are there any side effects from using metal or fabric to replace the bone in the skull?
    • When can I get back to my normal activities?
    • What is my chance of a full recovery?

    Causes And Risk Factors For Brain Cancer

    The exact cause of brain cancer is unknown. However, factors that can increase your risk of brain cancer include exposure to high doses of ionizing radiation and a family history of brain cancer.

    Cancer in another part of your body is also a risk factor for developing a tumor in the brain, though these arent called brain cancer. They are cancers that have spread to the brain.

    Cancers that commonly spread, or metastasize, to the brain include:

    • melanoma, which is a type of skin cancer

    Other factors that might be related to developing brain cancer include:

    • increased age
    • long-term smoking
    • exposure to pesticides, herbicides, and fertilizer
    • working with elements that can cause cancer, such as lead, plastic, rubber, petroleum, and some textiles

    Types Of Brain Tumors

    Primary Brain Tumors

    Tumors that begin in brain tissue are known as primary brain tumors and are classified by the type of tissue in which they originate. The most common brain tumors are gliomas, which begin in the glial or supportive tissue. There are several types of gliomas:

    • AstrocytomasThese tumors arise from small, star-shaped cells called astrocytes. They may grow anywhere in the brain or spinal cord. In adults, astrocytomas most often arise in the cerebrum. In children, they occur in the brain stem, the cerebrum and the cerebellum. A grade III astrocytoma is sometimes called anaplastic astrocytoma. A grade IV astrocytoma is usually called glioblastoma multiforme.
    • Brain stem gliomasThese tumors occur in the lowest, stem-like part of the brain. The brain stem controls many vital functions. Most brain stem gliomas are high-grade astrocytomas.
    • EpendymomasThese tumors usually develop in the lining of the ventricles. They may also occur in the spinal cord. Although these tumors can develop at any age, they are most common in childhood and adolescence.
    • OligodendrogliomasThese tumors occur in the cells that produce myelin, the fatty covering that protects nerves. These tumors usually arise in the cerebrum. They are rare, grow slowly and usually do not spread into surrounding brain tissue. They occur most often in middle-aged adults but have been found in people of all ages.

    Withdrawing From The World

    For most people, withdrawal from the world is gradual.

    Your loved one may experience extreme tiredness and spend more and more time in bed and/or asleep. They may also be drowsy and less engaged or interested in what is going on around them, when theyre awake. This is normal. You may need to draw on non-verbal cues to understand how they are feeling.

    Some people become calm and tranquil. Others can become confused and agitated.

    Eventually they may drift into unconsciousness. This may last for a few minutes, hours or even days.

    What can I do to help?

    While theyre still mobile, if they become confused or agitated, try to make their environment as safe as possible. Try not to antagonise them – if theyre refusing to do something you want them to do, ask yourself if its really necessary. If behavioural strategies dont work, speak to your healthcare team, as they can give medications to help calm your loved one.

    As they become confined to bed and more withdrawn, they may still be aware of your presence, so continue to talk to them. Share fond memories, and explain any care that is being given to them. You could play their favourite or soothing music, or read their favourite book to them.

    Dont be afraid to touch them. Holding their hand or stroking their head can be reassuring and calming for them.

    When To See Your Gp

    Symptoms of Brain Tumors

    It’s important to see a doctor if you develop persistent and worrying symptoms that may be caused by a brain tumour. While it’s unlikely that you have a tumour, it’s best to be sure by getting a proper diagnosis.

    If your GP is unable to identify a more likely cause of your symptoms, they may refer you to a neurologist for further assessment and tests, such as a brain scan.

    Treating Malignant Brain Tumours

    If you have a malignant brain tumour, you’ll usually need surgery to remove as much of it as possible. Radiotherapy and/or chemotherapy may then be used to treat any remaining cancerous tissue.

    The aim of this is to remove or destroy as much of the tumour as possible, ideally getting rid of the cancerous cells completely. However, this isn’t always possible and most malignant brain tumours will eventually return after treatment.

    If your tumour does return after treatment, or you have a secondary brain tumour , a cure isn’t usually possible. Treatment can instead be used to control your symptoms and prolong life.

    How Often Do Brain Tumor Headaches Occur

    Some people with a brain tumor never experience headaches, while others have headaches daily. Steroids may help provide relief once a brain tumor diagnosis is confirmed. But even if headaches go away, they may return later. Such reappearances can signal changes within the tumor, an increase in tumor-related brain swelling or a return of the tumor after treatments.

    Causes Of Malignant Brain Tumours

    Microsurgical Resection of a Brain Tumor

    Most malignant brain tumours are caused by a cancer that started somewhere else in the body and spread to the brain, through the bloodstream. These are known as secondary tumours.

    • von Hippel-Lindau syndrome
    • Gorlin syndrome

    Unlike most brain tumours, tumours associated with these conditions tend to develop in childhood or early adulthood.

    What Are Treatment Options For Medulloblastoma

    The first treatment for medulloblastoma 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 medulloblastomas receive further treatments. Treatments may include radiation, chemotherapy, or taking part in clinical trials. Surgery is usually followed by radiation to the brain and spine since this disease tends to spread in the brain and spine. Because of problems with bone marrow and surrounding organs that occur with brain and spine radiation, proton beam radiation therapy is often recommended. Chemotherapy may also be part of the treatment plan, depending on the subtype and amount the tumor has spread. Clinical trials, with new chemotherapy, targeted therapy, or immunotherapy drugs, may also be available and can be a possible treatment option. It is important to seek expert recommendations from a neuro-oncologist with experience in adult medulloblastoma. Treatments are decided by the patients healthcare team based on the patients age, remaining tumor after surgery, tumor type and tumor location.

    Open Clinical Studies for Medulloblastoma

    What Does It Look Like On An Mri

    Medulloblastomas usually appear as a solid mass in the cerebellum, which is the portion of the brain in the back of the head between the cerebrum and the brain stem. The tumor often brightens with contrast. Once the mass is known to be a medulloblastoma, a MRI of the spinal cord is recommended to see if it has spread.

    Confusion Conditions: Is It A Brain Tumor Migraine Or Something Else

    Symptoms of brain tumors can also be similar to those of other medical conditions, such as headaches and multiple sclerosis .

    Most headaches do not signal the presence of a brain tumor, and experiencing a headache by itself is usually not a cause for concern.

    However, signs that a headache could be a symptom of a brain tumor include:

    • persistent headaches, particularly if the person has no history of severe headaches
    • headaches that increase in intensity over time
    • headaches that are worse in the morning
    • headaches that wake people up from sleep

    If a person experiences frequent or severe headaches, they may have migraine, tension, or cluster headaches. These can also create feelings of nausea.

    Symptoms of migraine can range from mild to severe and include:

    • nausea, which may worsen with activity
    • a throbbing sensation on one side of the head
    • increased sensitivity to light and sound
    • facial pain
    • communication difficulties
    • changes in personality or behavior

    A doctor will take a full medical history and perform a range of neurological tests to see what is causing the symptoms. For example, they may:

    • run CT scans or MRI scans, to provide an image of the brain
    • conduct tests to check balance, vision, and coordination

    Also, if they locate a tumor in the brain, they may take a tissue sample, or biopsy, to find out what type it is.

    Brain Tumour Risk Factors

    How to Read an MRI of the Brain | First Look MRI

    There are some things that can make it more likely to develop a brain or spinal cord tumour. These are called risk factors and they include:

    Family history while it is rare for brain tumours to run in families, a fault in the genes, usually passed down from either the mother or father, can increase the risk of developing a brain tumour.

    Radiation therapy people who have had radiation therapy to the head, particularly to treat childhood leukaemia, may have a slightly higher risk of developing a brain tumour.

    Having these risk factors doesnt mean you will develop a brain or spinal cord tumour. Often there is no clear reason for getting a brain or spinal cord tumour. If you are worried about your risk factors, ask your doctor for advice.

    Living With Advanced Cancer

    Advanced cancer usually means cancer that is unlikely to be cured. Some people can live for many months or years with advanced cancer. During this time palliative care services can help.

    Most people continue to have treatment for advanced cancer as part of palliative care, as it helps manage the cancer and improve their day-to-day lives.

    Many people think that palliative care is for people who are dying but palliative care is for any stage of advanced cancer. There are doctors, nurses and other people who specialise in palliative care.

    Palliative care treatment may include chemotherapy, radiation therapy or another type of treatment. It can help in these ways:

    • slow down how fast the cancer is growing
    • shrink the cancer
    • help you to live more comfortably by managing symptoms, like pain.

    Treatment depends on:

    When To See A Gp

    See a GP if you have these types of symptoms, particularly if you have a headache that feels different from the type of headache you usually get, or if headaches are getting worse.

    You may not have a brain tumour, but these types of symptoms should be checked.

    If the GP cannot identify a more likely cause of your symptoms, they may refer you to a doctor who specialises in the brain and nervous system for further assessment and tests, such as a brain scan.

    Brain Cancer Survival Rate

    The average five-year relative survival rate for malignant brain tumors is 35.6 percent, according to the National Brain Tumor Society. This means that 35.6 percent of people who are diagnosed with brain cancer are still alive five years after their tumor is found.

    Many factors affect survival following a brain cancer diagnosis, including:

    • Age
    • Tumor type
    • Grade

    For example, according to the American Cancer Society, the five-year relative survival rate by age bracket for glioblastoma, the most common type of primary malignant brain tumor, is:

    • 22 percent for people aged 20 to 44
    • 9 percent for people aged 45 to 54
    • 6 percent for people aged 55 to 64

    This means that the younger you are, the higher the estimate of survival after five years. As a general rule, survival is longer with lower-grade brain tumors, but brain cancer survival data isnt often categorized by grade.

    Its also important to keep in mind that survival estimates are just thatestimates. They are based on past data and older treatments. Advances continue to be made in medicine, and you should feel comfortable asking your care team to go over what these estimates mean for you, and what newer treatments may be appropriate for you.

    What Are The Grades For Benign And Cancerous Brain Tumors

    Experimental Brain Tumors: Current Concepts

    Doctors group brain tumors by grade. The grade of a tumor refers to the way the cells look under a microscope:

    • Grade I: The tissue is benign. The cells look nearly like normal brain cells, and they grow slowly.
    • Grade II: The tissue is malignant. The cells look less like normal cells than do the cells in a Grade I tumor.
    • Grade III: The malignant tissue has cells that look very different from normal cells. The abnormal cells are actively growing .
    • Grade IV: The malignant tissue has cells that look most abnormal and tend to grow quickly.

    Cells from low-grade tumors look more normal and generally grow more slowly than cells from high-grade tumors . Over time, a low-grade tumor may become a high-grade tumor. However, the change to a high-grade tumor happens more often among adults than children.

    Role Of Neurosurgery In Diagnosis

    If CT or MRI scans indicate concern for a tumor, a neurosurgeon who is experienced in brain tumor surgery will join your care team. This is important for the accurate diagnosis and removal of as much underlying tumor as possible while leaving healthy tissue intact. Available evidence and general consensus among neurosurgeons and neuro-oncologists indicate that the more completely a tumor is surgically removed, the greater the chance of survival and controlling your symptoms. This is true for both malignant and nonmalignant tumors.
