Life Expectancy For Brain Metastases
Life expectancy in patients with brain metastases depends upon the variety of factors. It depends upon the stage at which the cancer is diagnosed. It also depends upon the type of primary cancer and its spread in other body parts. The life expectancy also depends upon the number of brain metastatic sites.
The complications related to brain metastases further depends upon the neurological damage due to tumor. Although various treatments are available for the management of brain metastases but none of the treatment completely cure the disease due to various reasons. Chemotherapy is rarely effective due to the fact that most of the chemotherapeutic drugs unable to cross the blood brain barrier at required concentration. Surgery of brain tumor is highly complicated and requires precision. Also, the patient and relative fears with surgery due to significant risk involved. Even if the risk of brain surgery is taken, most of the times the tumor cannot be completely removed due to its inaccessibility.
Causes Of Malignant Brain Tumours
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.
Facts About Stage 4 Brain Cancer Life Expectancy
According to the available statistics, every year, more than 13000 deaths due to brain cancer are recorded in the United States. Brain cancer prognosis is very bleak. Though the survival rate for advanced stage cancer is very poor, there are examples of patients who have lived for more than five years. Brain cancer stage 4 life expectancy depends upon the patients will power, determination, positive attitude, love and support from the family and the overall mental and physical health.
The survival rate for the cancer varies from country to country. On an average, it is about 20%, which means about 20% people diagnosed with brain cancer may live up to five years.
- Life expectancy at stage 4, without any treatment, is about 2 3 months, as brain edema eventually leads to death.
- Those diagnosed with slow growing malignant tumor called oligodendroglioma, generally spend 16 18 years with cancer.
- At stage 4, the life expectancy for patients over the age of 60 is about 1 2 years.
- A young adult with brain cancer is likely to live with the cancer for more than 5 years.
- The 5 year survival rate for the cancer at fourth stage in infants is lower than 30%.
- Life expectancy for tumors called glioblastoma multiforme is very very poor. Even after proper surgery and treatment the survival rate is 12 18 months only. This type of tumor is commonly found in adult patients. Only 4% patients survive up to 5 years.

Help With Making Plans
It can be helpful to talk through your options with your closest family or friends while you are able. This can help to avoid misunderstanding about what everyone thinks is best. Talking through the options will help everyone to make plans that you all agree on.
You might feel happier knowing that you have made the best decisions for all of you. It can be a very heavy burden on families to decide what to do during a crisis. It might be easier if they know what you would have wanted.
Caring for someone that is dying can be a huge emotional and physical challenge. It’s important that you get all the help and support you need.
Understanding The Symptoms Of A Brain Tumor Or Brain Metastasis
A primary brain tumor is a tumor that starts in the brain. A secondary brain tumor is a cancerous tumor that starts in another part of the body and then spreads to the brain. The spread of cancer from the place where the cancer began to another part of the body is called metastasis, or metastases when there are multiple areas of spread. Brain metastases can develop from any type of cancer. The types of cancer most likely to spread to the brain are breast cancer, lung cancer, kidney cancer, and melanoma.
The symptoms of a brain tumor or brain metastases depend on where in the brain the tumor forms, the tumors size, and how fast the tumor spreads. Cancer treatment can also cause symptoms and side effects. Your loved one may have several symptoms or none at all.
Types of symptoms that may occur from cancer in the brain are:
Physical symptoms. These can include headaches, seizures, nausea, muscle weakness, vision problems, and bowel and bladder problems.
Cognitive symptoms. When the tumor affects how a persons brain processes information, symptoms can include personality changes, confusion, impaired judgment, memory loss, and socially inappropriate behavior.
Options to relieve symptoms may include:

How Do You Decide Which Metastatic Brain Cancer Treatment Is Right For You
Your neurosurgeon will discuss the most appropriate treatment approach with you by considering these and other factors:
- The type of primary cancer, your response to treatment and current status
- The location and number of metastatic tumors within the brain or spine
- Your general health and preferences regarding potential treatment options
- Your current symptoms
Along with benefits, doctors also consider the potential risks and side effects of any treatment. Many patients are worried about the effects of radiation. Others hesitate about the idea of surgery. Tell your doctor about your concerns they are important to consider.
Symptoms Caused By The Position Of A Tumour
Different areas of the brain control different functions, so the symptoms caused by a brain tumour will depend on where the tumour is located. For example, a tumour affecting:
- the frontal lobe may cause changes in personality, weakness in one side of the body and loss of smell
- the temporal lobe may cause forgetfulness, language problems and seizures
- the parietal lobe may cause aphasia and numbness or weakness in one side of the body
- the occipital lobe may cause loss of vision on one side
- the cerebellum may cause a loss of co-ordination, flickering of the eyes, vomiting and a stiff neck
- the brain stem may cause unsteadiness and difficulty walking, facial weakness, double vision, and difficulty speaking and swallowing

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.
A Neurosurgeon Explains: Astrocytoma Tumors
Vikram C. Prabhu, MD, FAANS
The brain is made up by many different cells, including neurons, which constitute the electric circuitry responsible for brain functions, and astrocytes, which provide the structure and support for neurons to work properly. Astrocytomas are tumors which originates from astrocytes, and, in adult individuals, they are the most common brain tumors. In the US, about 15,000 new astrocytomas are diagnosed every year. Males are slightly more affected than females, with a ratio of 1.3/1.

A Meningioma Diagnosis May Occur When The Doctor Is Looking For Something Else
Brain tumor diagnosis is often incidental that is, the doctor discovers a tumor on a CT or MRI while examining the individual for another reason such as a head injury or another neurologic problem.
When a doctor diagnoses a meningioma, you will get further tests to find out how the tumor is likely to behave. Based on these data, a neurosurgeon will recommend removing the tumor or just watching it to see if it grows.
Brain Tumors In Adults
- An estimated 69,950 adults age 40+ will be diagnosed with a primary brain tumor in 2021 in the U.S.
- Brain tumors are the eighth-most common cancer overall among persons age 40+ years, ninth-most among males, and fifth-most among females in this age group
- Brain tumors are the third-leading cause of cancer-related death in individuals 40 years and older
- The five-year relative overall survival rate for adults diagnosed with a primary brain tumor is 71.7%
- The rate is 21.5% for malignant tumors and 90.2% for non-malignant tumors
Choosing Not To Have Treatment
If your tumour is at an advanced stage or in a difficult place in the brain, a cure may not be possible and treatment may only be able to control the cancer for a period of time. This means you will be getting the side effects of treatment without getting rid of the tumour.
In this situation, it may be difficult to decide whether or not to go ahead with treatment. Talk to your doctor about what will happen if you choose not to be treated, so you can make an informed decision.
If you decide not to have treatment, you will still be given palliative care, which will control your symptoms and make you as comfortable as possible.

What Is A 5
A relative survival rate compares people with the same type of tumor to people in the overall population. For example, if the 5-year relative survival rate for a specific type of brain tumor is 70%, it means that people who have that tumor are, on average, about 70% as likely as people who dont have that tumor to live for at least 5 years after being diagnosed.
Diagnosing Malignant Brain Tumours
See your GP if you develop any of the symptoms of a malignant brain tumour, such as a persistent and severe headache.
Your GP will examine you and ask about your symptoms. They may also carry out a simple neurological examination .
If they suspect you may have a tumour, or they are not sure what’s causing your symptoms, you’ll probably be referred to a neurologist .

Risk Factors For Developing Brain Tumors
A risk factor is something that increases your chances of developing a certain disease or condition. Factors that increase your chances of a brain tumor are:
- Radiation exposure
- A condition that affects the immune system
- Family history of certain types of cancer
- Exposure to harmful chemicals like formaldehyde and vinyl chloride
Any cancer in the body can spread to the brain, but the most common include:
- Lung cancer
- Numbness in extremities
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.

Emotional Impact Of A Brain Tumor
Maybe you have just been told you have a brain tumor or maybe youve been living with that knowledge for a while. You may feel that you are on an emotional rollercoaster scared and angry one day, then hopeful and positive the next day. Your life will likely be different from what it was before, but if you are like most people, you will find a way to accept lifes latest development and focus your energy on adjusting to this new reality.
Emotional Effects of a Brain Tumor
Although everyones exact emotional response is unique, many people with a brain tumor report going through the same six phases. All are normal.
Nothing quite prepares you for the moment when you hear the words you have a brain tumor from your doctor. You may feel numb or confused. Do not be surprised if your first reaction is a blank stare and a feeling of dissociation instead of an emotional outburst. This is a defense mechanism your mind uses to avoid feeling overwhelmed.
As you move forward from the initial shock, it is natural to deny that anything is wrong and act as if nothing happened. Denial is another defense mechanism the mind uses to avoid processing the full impact of a brain tumor diagnosis at one time.

Are There Different Types Of Benign Brain Tumors
The most commonly diagnosed benign brain tumors include:
- Meningioma – tumor arising from the membranes covering the brain and spinal cord accounts for about 20% of brain tumors.
- Schwannoma – tumor in the 8th cranial nerve arising from Schwann cells accounts for about 9% of all brain tumors.
- Pituitary Adenomas – pituitary gland tumor accounts for about 8% of brain tumors.
- Hemangioblastomas – vascular tissue mass accounts for about 2% of brain tumors.
- Craniopharyngioma – cystic tumor from cell remnants of Rathke’s pouch , usually occurring in children accounts for about 1%-3% of brain tumors.
- Choroid Plexus Papilloma – choroid plexus tissue mass that blocks cerebrospinal fluid flow, usually in children accounts for less than 1% of brain tumors.

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:
What Causes A Brain Tumor
Doctors are not sure what causes most brain tumors. Mutations or defects in genes may cause cells in the brain to grow uncontrollably, causing a tumor.
The only known environmental cause of brain tumors is having exposure to large amounts of radiation from X-rays or previous cancer treatment. Some brain tumors occur when hereditary conditions are passed down among family members.

What Happens At The End
What happens at the end depends on how your brain tumour develops. Talk to your doctor or specialist nurse. They know your situation and might be able to give you specific information about what might happen.
When brain tumours grow very large, the pressure inside your head increases, causing drowsiness. At first it might be possible to control this by increasing your steroid dose. Eventually the steroids will not be able to reduce the swelling any further.
You might get headaches and sickness. These can often be controlled with painkillers and anti sickness medicine. But you might get drowsier and will need to sleep more often. This can come on quite suddenly or slowly. At this stage, you may be able to lead a relatively normal life. But you might sleep more than you used to.
Some people who have never had seizures , might have some in the last few weeks of their life. Your doctor can start you on anti epileptic medication if this happens.
Gradually you will need to sleep more and more and it may become more difficult to wake you. Eventually, most people slip into unconsciousness. You might be unconscious for a few days or weeks before you die. During this time you will need nursing care to make you comfortable.
What’s The Outlook For People With A Brain Tumor
The outcome for people with brain tumors varies greatly. Factors that can affect prognosis include the tumorâs type, grade, and location successful removal of all of the tumor and your age and overall health.
In many people, doctors can successfully treat a brain tumor. Other people live active and fulfilling lives with brain tumors that do not cause symptoms.
In some people, brain tumors can recur after treatment. These people may need to continue treatments, including chemotherapy or radiation, to keep the tumor from growing or spreading. After brain tumor treatment, you should follow up with your doctor regularly.
Other Nervous System Structures Include:
Cell division and cell death are a normal process in the body to replace old or damaged cells. Sometimes this division and new cell growth can continue after it is supposed to stop. This excess growth forms a tumor. Benign tumors grow in the area, but do not invade nearby tissue. Malignant tumors are cancers that do grow into nearby tissue. It is not always clear what causes the abnormal growth, but it often is a combination of genetic and environmental factors.
