The Cause Of Brain Cancer Is Usually Unknown
Most people diagnosed with a primary brain tumor do not have any known risk factors. However, certain risk factors and genetic conditions have been shown to increase a persons chances of developing one, including:
- The risk of a brain tumor increases as you age.
- People who have been exposed to ionizing radiationsuch as radiation therapy used to treat cancer and radiation exposure caused by atomic bombs have an increased risk of brain tumor.
- Rare genetic disorders like Von Hippel-Lindau disease, Li-Fraumeni syndrome, and Neurofibromatosis may raise the risk of developing certain types of brain tumors. Otherwise, there is little evidence that brain cancer runs in families.
What Is The Treatment For Brain Cancer
A treatment plan is individualized for each brain cancer patient. The treatment plan is constructed by the doctors who specialize in brain cancer, and treatments vary widely depending on the cancer type, brain location, tumor size, patient age, and the patient’s general health status. A major part of the plan is also determined by the patient’s wishes. Patients should discuss treatment options with their health care providers.
Surgery, radiation therapy, and chemotherapy are the major treatment categories for most brain cancers. Individual treatment plans often include a combination of these treatments. Surgical therapy attempts to remove all of the tumor cells by cutting the tumor away from normal brain tissue. This surgery that involves opening the skull is often termed invasive surgery to distinguish it from noninvasive radiosurgery or radiation therapy described below. Some brain cancers are termed inoperable by surgeons because attempting to remove the cancer may cause further brain damage or death. However, a brain cancer termed inoperable by one surgeon may be considered operable by another surgeon. Patients with a diagnosis of an inoperable brain tumor should consider seeking a second opinion before surgical treatment is abandoned.
Other treatment options may include hyperthermia , immunotherapy , or steroids to reduce inflammation and brain swelling. These may be added on to other treatment plans.
What Tests Do Doctors Use To Diagnose Brain Cancer
The initial test is an interview that includes a medical history and physical examination of the person by a health care provider. The results of this interaction will determine if other specific tests need to be done.
The most frequently used test to detect brain cancer is a CT scan . This test resembles a series of X-rays and is not painful, although sometimes a dye needs to be injected into a vein for better images of some internal brain structures. Another test that is gaining popularity because of its high sensitivity for detecting anatomic changes in the brain is MRI . This test also shows the brain structures in detail better than CT. If the tests show evidence of brain cancer, then other doctors such as neurosurgeons and neurologists that specialize in treating brain ailments will be consulted to help determine what should be done to treat the patient. Occasionally, a tissue sample may be obtained by surgery or insertion of a needle to help determine the diagnosis. Other tests may be ordered by the health care practitioner to help determine the patient’s state of health or to detect other health problems. These tests help differentiate between cancerous and non-cancerous conditions in the brain that may produce similar symptoms .

Treatment And Medication Options For Glioblastoma
Glioblastoma has long been a source of frustration for oncologists, who have not been able to treat it nearly as effectively as they would like to. They have made very slow progress at extending the life span of patients with the illness.
Glioblastoma is treated with surgery, radiation, and chemotherapy.
Unfortunately, glioblastomas are surrounded by migrating, infiltrating tumor cells that invade surrounding tissues, making it impossible for surgeons to ever remove the tumor entirely.
One of the challenges of treating glioblastomas is that the brain has a layer of cells called the blood-brain barrier that blocks entry to substances that could potentially harm the brain. Its difficult to get certain chemotherapy drugs past that wall.
Clinical Trials For New Treatments
Researchers are always finding new ways to treat metastatic brain tumors. These new methods are tested in clinical trials. Talk with your health care provider to find out if there are any clinical trials you should consider.
Johns Hopkins Comprehensive Brain Tumor Center
Every metastatic brain tumor, and every patient, is different. The specialists at Johns Hopkins take the time to determine which treatment or combination of treatments will be the most effective for you.

What Happens At The End Of Life
Everybodys death will be different, but there are some changes that are common to the dying process.
For some people who are living with a terminal brain tumour diagnosis, having some information about the process of dying can be comforting.
Family and friends, who are likely to be with a loved one at the end, often want to know, so they know what is normal and when they should call the healthcare professionals.
However, not everyone will want to know the details of what may happen when someone dies.
Its completely understandable if youre not ready for this information at the moment.

What to expect when somebody is dying
Every persons experience of dying will be different, so its difficult to predict exactly what or how quickly any changes will happen.
Some people will decline very gradually but for others it may be very quick.
There are some changes that are common to the dying process which are likely to happen in the last few weeks, days and hours.
The changes that happen when a person with a brain tumour is dying fall into five categories:
- Less need for food and drink
- Withdrawing from the world
- Changes that people with brain tumours may specifically experience
- Changes which happen shortly before death.
How Cancer Causes Death
Even though cancer can lead to death, it’s not necessarily cancer that causes someone to die. Causes of cancer deaths can include:
- Organ failure due to the size and stress of a tumor
- Complications during surgery
- Organ rupture due to tumor size
- Infection due to the immune system’s ability to fight off illness while on cancer treatment
Since all the organs in our body connect one way or another, all it takes is for one to begin shutting down, and the rest may start to follow suit. In the end, the person with cancer passes away.
Depending on the type of cancer, the cause of death can vary. Here are some more details on how cancer can cause death.

Chemotherapy For Metastatic Brain Tumors
Because traditional chemotherapy cannot cross the blood-brain barrier, newer treatments called targeted therapy are used as the primary type of chemotherapy for treating metastatic brain tumors.
These drugs identify and attack cancer cells with minimal harm to normal cells while preventing the growth and spread of cancer cells. Targeted therapy can be administered after surgery or in conjunction with radiation therapy to destroy remaining cancer cells.
Targeted therapies used to treat metastatic brain tumors include:
- Trastuzumab for breast cancer that has spread to the brain
- Erlotinib for the most common type of lung cancer that has spread to the brain
What Are Surgical Treatment Plans For Brain Cancer
- The treatment protocols vary widely according to the location of the tumor, its size, grade, and type, the patient’s age, and any additional medical problems that the person may have.
- The most widely used treatments are surgery, radiation therapy, and chemotherapy. As mentioned in some cases, more than one of these treatment types is used.
Most people with a brain tumor undergo surgery.
- The purposes of surgery are to confirm that the abnormality seen on the brain scan is indeed a tumor, to assign a grade to the tumor, and to remove the tumor. If the tumor cannot be removed completely, the surgeon will at least take a sample of the tumor to identify its type and grade.
- In some cases, mostly in benign tumors, the disease can be completely cured by surgical removal of the tumor. A neurosurgeon will attempt to remove the tumor when possible.
Patients may undergo several treatments and procedures before surgery.
- They may be given a steroid drug, such as dexamethasone , to relieve swelling.
- They may be treated with an anticonvulsant drug, such as levetiracetam , phenytoin , or carbamazepine , to relieve or prevent seizures.

The Impact Of Brain Tumours
There are around 5,400 deaths due to brain tumours every year in the UK, more than 100 deaths every week.
But just as important is the toll on those who survive, or who are living with brain tumours. The brain is the most important and complex of our organs and a tumour can cause huge, irreversible damage. And treatment that may be life-saving can cause devastating collateral damage. This is particularly pertinent in children, whose brains are still developing and who must carry the burden of any disabilities and health problems through their whole lives.
James, pictured above left, was diagnosed with a brain tumour at the age of five. His tumour was low-grade, but caused relentless seizures. After a number of years of ‘watch and wait’ doctors decided that the damage being caused by the seizures now tipped the balance in favour of surgery to remove the tumour. You can read James’s story here.
Metastatic Brain Cancer Prognosis
Prognosis for metastatic brain cancer varies greatly. Keep in mind that each patient is unique, and with newer treatments, many patients live longer. Speaking with your care team about your unique diagnosis can provide an accurate prognosis.
Palliative Care at Johns Hopkins
Palliative care is specialized medical care that helps patients facing serious illnesses and their families by adding an extra layer of support.
Palliative care teams can help with the symptoms and the stress of living with a serious illness, including controlling pain, providing support for the mental and emotional effects of an illness, and managing other symptoms.

Operating On The Inoperable
Eileen Beckerts tumor was located directly on the speech area of her brain. She had been told that it was inoperable. Because of the poor prognosis for brain cancer in general, and the propensity of tumors to grow back after surgery, many surgeons do not even try operations in cases like this. One result is that they do not develop the skill that comes with having done hundreds of them.
We believe in giving patients their best chance. As Allan Friedman puts it, time is precious. No one lives forever, but he sees his job as getting his patients as much quality time as possible. Many patients he sees have already been turned away by other surgeons.
Allan was an unlikely candidate for excelling at neurosurgery. The rst time he observed an operation, he fainted when the surgeon made the rst cut. He now says that, while you may never get used to it, the surgery eventually becomes fairly routine. Now, he does 12 operations in a typical week, each lasting about 4 hours.
To perform a difcult operation like Eileens, a surgeon must visualize the procedure in his head before he begins. He takes every precaution to avoid mistakes and so goes in with condence. You dont think in terms of what you are going to do. You think in terms of what pitfalls you are likely to encounter and how to avoid or deal with them, says Allan.
We Understand The Power Of Statistics
That’s why we leave no stone unturned when it comes to the latest analysis surrounding the devastating impact of brain tumours in the UK.
The shocking statistics speak for themselves:
- Too many people are being faced with the devastating diagnosis each year every two hours, someone is diagnosed with a brain tumour in England
- In the UK, 16,000 people each year are diagnosed with a brain tumour
- Only 12% of brain tumour patients survive beyond five years of their diagnosis, whereas over 70% of breast cancer and over 40% of leukaemia patients survive beyond five years
- Brain tumours are the chief cause of cancer deaths in children and young people – in 2015, the number of children dying from cancer was 194, with brain tumours taking 67 young lives and leukaemia 46
- Brain tumours continue to kill more children and adults under the age of 40 than any other cancer

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.

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 .
What Happens When Cancer Spreads To The Brain
Cancer cells can break away from the primary tumor and travel to the brain, usually through the bloodstream. They commonly go to the part of the brain called the cerebral hemispheres or to the cerebellum, where they form a mass.
Some metastatic brain tumors appear many years after the primary cancer. Others metastasize so quickly that they are identified before the primary cancer.
When the cancer cells reach the brain and form a tumor, it may lead to a variety of symptoms that can be shared by nonmetastatic brain tumors as well.

What Are The Complications Associated With A Brain Tumor
Some people with a brain tumor â whether it is benign or malignant â experience complications as the tumor grows and presses on surrounding tissue. These complications include:
- Faster or slower breathing and pulse rates.
- Numbness that interferes with feeling pressure, heat or cold on the body.
- Weakness or inability to move a leg or arm on one side of the body.
- Vision, hearing and smelling problems.

Less Need For Food And Drink
When someone is dying, their bodys metabolism will slow down. This means theyre less able to digest food and take the goodness from it. As a result, their appetite may reduce and they may start to lose weight.
The effort of eating may become too much. This may be either because the person is less able to control and co-ordinate their muscles causing difficulty swallowing. Or it could be simply because the person is physically exhausted. Some people may feel, or be, sick.
It can be difficult to see your loved one this way and many peoples instinct is to care for them by making sure they eat, perhaps offering them tempting meals that are their favourite.
People worry that their loved one will starve if they dont eat.
However, because the body is shutting down, they dont need so much food. Changes in the body of people with advanced illness are different to the changes in healthy people who are forced to go without food. People who are dying often start to lose weight even while their appetite is still fairly normal, as their body cant make use of the food.
As with food, the effort of drinking may become too much, often due to difficulty with swallowing. In addition, because the body is shutting down, it doesnt need so much water.
Many people are also catheterised when theyre at the end of life. This means a tube is inserted into their bladder to drain their urine into a bag. As a result, they urinate less, so need less fluid.
What about medications?
