signs of brain cancer in children

Increase in intracranial pressure: A brain tumor can exert pressure on its surrounding tissues and might also block the ventricles or the brain regions filled with fluid. This in turn will prevent the cerebrospinal fluid from flowing normally. As a result of all these changes in the brain, the patient’s intracranial pressure increases. Increase in intracranial pressure on the other hand leads to behavioral and emotional changes in the affected child; the child might suffer from depression, personality changes and irritability. There are also instances when children with brain tumor vomit during the morning due to increase in their intracranial pressure. The other symptoms accompanying these problems are drowsiness, nausea and headaches. The augmented intracranial pressure might also affect the patients cardiac and respiratory systems when not treated at the right time; the patient might also get into coma.

Seizures: Children suffering from brain cancer often develop seizures. The seizures occur due to irregularity in the electrical activities within the brain. How will you know that you child is having seizures? The common signs of seizures are: unusual sensations, unconsciousness and convulsions. In some seizures are also manifested in form of numbness, speech problems and muscle twitching.

You may have many questions regarding your tumor and the possible brain cancer treatment options. The side effects of the treatment, too, need to be discussed. Do not hesitate to consult your doctor.

Overview

Brain cancer treatment is generally complicated. A team of doctors needs to be consulted.

• This team of doctors generally comprises neurosurgeons, oncologists, and radiation oncologists. Your general practitioner plays a pivotal role in this team. In some cases, dietitians, social workers, and physiotherapists, too, play an important role.
• The treatment options depend on the location of the tumor, and also it size and type. The individual’s age and existing medical conditions also play an important role.
• The most common treatments for brain cancer include surgery, chemotherapy, and radiation therapy. In some instances, a combination of these techniques is used.

Brain cancer surgery

• Surgery is the most common technique to treat brain cancer. One of the aims of surgery is to ascertain the type of tumor. Removal of the tumor is also vital. Sometimes, the neurosurgeon will collect the sample of the tumor if the tumor cannot be removed.
• In benign forms of brain cancer, symptoms can be completely eliminated with the removal of the tumor. A neurosurgeon is specially qualified to remove these tumors.
• Brain tumors can be destroyed without opening the skull through stereotactic surgery, which is a ‘knifeless’ procedure. CT and MRI scans are used to diagnose the exact location of brain tumor. Radiation beams that are high in energy are focused on the tumor from different directions. Radiation disintegrates the tumor. This procedure is also known as ‘gamma knife’.
• Knifeless techniques have far fewer complications. The recovery time is also much quicker.

Individuals may need to undergo numerous treatments and procedures prior to surgery:

• You may be put on a steroidal drug, known as dexamethasone, in order to relieve swelling.
• Carbamazepine may be prescribed to prevent the occurrence of seizures. It is an anticonvulsant drug.
• A slender, plastic tube (known as shunt) may be used in order to drain the excessive cerebrospinal fluid that collects near the brain. While one end of the shunt is inserted into the cavity where collection of fluid occurs, the other end is threaded under the skin to connect to another part of the body. This results in the complete drain of the fluid.

Radiation Therapy

Radiation therapy is also known as radiotherapy. It involves usage of rays that are high in energy. These rays destroy tumor cells. It also prevents the cells from expanding and multiplying.

• Brain Cancer Radiation therapy is prescribed for individuals who sometimes cannot undergo surgery. In some instances, this therapy is used post surgery to disintegrate malignant tumor cells.
• Radiation therapy is a local one. This would mean that it targets only selected cells. It has no effect on other cells of the body or brain.

However a global research group helmed by LICR scientists at the Univ. of California, San Diego School of Medicine have reported in the mid-Aug edition of ‘Genes & Development’ that they have uncovered a novel signalling path in-between the GBM cells which in case finally obstructed or hampered can considerably slacken or lower tumor development and malignance.

GBMs surpass several cancerous forms in the varied groupings of cell sub-forms which feature vast heritable disparity. Cancer combatant treatments which are created for targeting a particular mutation or cellular path have a tendency of being lesser effectual while tackling heterogeneous state of tumor.

Doctor Frank Furnari, associate study researcher stated that innumerable heritable modifications might be one of the chief reasons for GBM’s lethality. Despite utmost therapy endeavours, the average survival rate in GBM cases identified is between 9 months to a year – a figure that has failed to change significantly since tens of years.

But, Furnari, an associate Prof. of medicine from the UCSD School of Medicine along with post-graduate fellow researchers observed that among GBMs merely a marginal number of tumor cells have a mutant type of the EGFR gene. Such cells impel the tumor’s swift, lethal development. Majority of the GBM’s tumor cells have a tendency of expressing wild-form or regular EGFR, still during self-expression, wild-form EGFR is a pitiable oncogene.

The researchers uncovered that cancerous cells having mutant EGFR (epidermal growth factor receptor) secreted molecules which caused adjoining cells having wild-form EGFR to hasten their cancerous development. Furnari pointed out that these mutant cells were actually giving instructions to other lesser malignant tumor cells in turning more cancerous.

Furnari stated that this signalling path present in-between GBM tumor cells was unidentified and does present a novel and rather hopeful link in the shield of glioblastomas. He added that in case cell communication could be inhibited or blocked then tumor growth could be slackened and thus might be better treated. Investigators have discovered duo molecules which seem to be triggering EGFR activity in mutant-free tumor cells.

The outcomes might additionally offer hints in the larger picture of the manner in which GBMs and other cancer types manage survival and flourish. Furnari mentioned that since long brain tumor studies have laid emphasis on the most lushly expressed mutations; however this study indicates that minor mutations also don a vital part.

Surgery by itself or merged alongside radiation therapy might be used in brain cancer treatments for several tumors inclusive of a number of ependymoma, craniopharyngioma, ganglioglioma, low grade astrocytoma and meningioma forms.

Tumors which have a tendency to spread into adjoining tissues in the brain like glioblastoma or anaplastic astrocytoma are incurable through surgical intervention. However, surgery could lessen the extent of tumor which would need to undergo chemotherapy or radiation therapy that could aid in improving the efficacy of such therapies. This might assist in prolonging life even though total tumor removal would not be possible.

Surgery could be one of the most viable brain cancer treatments that might additionally assist in improving a number of symptoms arising due to brain tumors, especially those that arise due to pressure build-up inside the cranium which could comprise of headache, feeling nauseous, puking and blurry eyesight. Surgery might additionally be helpful in controlling seizure attacks.

However surgery might not be an ideal choice in several scenarios. For instance, when the tumor is quite deeply set inside the brain or the patient is incapable of tolerating a major surgery due to other health concerns. Surgery is additionally not performed in case it would need removal of some portions of the brain needed for existence like brain stem.

Surgery is also not quite effectual in case of a number of brain tumor types like lymphoma, though it might be employed for acquiring a biopsy for identification.

Craniotomy- This is the key form of surgery to treat brain tumors and cranium would be opened during the procedure after anesthesizing the patients (general) for promoting deep slumber. Alternately the patient could be wakeful for some portion of the surgery (with the operated region de-sensitized) in case brain functioning is to be evaluated during the course of the surgery. Shaving of a section of the brain might become necessary. Firstly, a slit would be made in the scalp and folding back of the skin would be done by the surgeon. The neurosurgeon would then employ a specially designed saw-like apparatus for removing a part of the cranium that is above the tumor.

Craniotomy is classically large-sized to enable the neurosurgeon in inserting a number of apparatus and viewing sections of the brain required to manoeuvre with complete safety. In case of deeply located tumors in the brain, a tiny slit would be done into the brain for facilitating easier accessibility to the tumor. CAT, ultrasound or Magnetic resonance imaging (MRI) could be employed to assist in locating the tumor and its borders.

Tumor removal is done in numerous ways based on the hardness or softness and if it has several or hardly any blood vessels. One approach would be using a scissor or scalpels for incising it out or ultrasonic generator device fitted onto a probe that might be introduced inside the tumor for breaking it up and liquefying it. A small-sized vacuuming apparatus would now be employed for suctioning it out.

Several apparatus could be of assistance to the neurosurgeon for seeing the tumor and adjoining brain tissues. A microscope could be employed for viewing the brain when the operation is being done. Image-steered surgery involves repetitive capturing of the tumor images during the surgery for revealing the tumor site and the neurosurgeon’s tools. This could facilitate risk-free and vastly far-reaching resecting of a number of brain tumors.

The neurosurgeon could view brain functioning via electrical stimulation of areas of the brain in and adjacent to the tumor and would help in showing whether such parts are controlling vital functioning.

Intraoperative cortical stimulation is a method used for lowering risk of removal of crucial brain portions. Functional MRI is another method employed for locating some brain function before operation which would help in identifying and preserving the area during surgery.

Mostly, the bone portion that has been taken out would be placed back and affixed to the cranium employing metallic screw, plate, wire or specialized stitch types. The operated side would heal in a number of weeks and recuperation in hospital is generally around four to six days depending on the size, how big the tumor was and the overall health condition of the patient.

Several diverse viruses have been evaluated in the past for cancer treatment, especially for treatment of those cancer forms that have no effectual recognized therapy techniques. The DKFZ scientists came to an early realization that H-1 parvovirus has significant benefits as compared to the other viral forms and effectual weaponry against brain cancer. Presently, they have been the pioneers at proving that cancerous glioblastomas have complete regression as a consequence of being treated with parvoviruses.

The therapy trials were done on rodents that have been administered brain tumor cells via embedding. No sooner had the brain tumor grown to a specific size; the rats were administered parvoviruses via directly injecting inside the tumor or through the blood. Among rats that had been given direct jab inside the tumor, there was visible shrinkage in tumors subsequent to merely 3 days and also subsided totally in 8 from 12 rats. The rats managed to survive and being asymptomatic whereas un-treated placebo set of rodents ailed from acute ailment symptoms within 3 weeks after tumor cells were implanted. In the intravenous-therapy rodent set, there was complete tumor regression in 6 from 9 of them. The rodents have managed to survive for over a year’s time and being asymptomatic or no late side-effects due to the treatment.

The study investigators noted no infection-associated harm in the nervous tissue adjoining the tumor and the viruses not spreading to the entire organism. Despite DNA of the virus being identifiable in all body organs subsequent to numerous days after parvovirus being transferred yet it was solely for a brief time period. The parvoviruses had caused infection in healthy cells though they did not create a novel viral cohort. But, in the tumor tissues, the parvoviruses exhibited reproduction and viral protein being manufactured was discernable in just these cells. In rodents not bearing tumors, the parvoviruses had no reproduction. Hence, it seems that existence of malignant cells was essential criteria for parvovirus reproduction.

The other reasons for parvoviruses being potent brain cancer combating weapons are because they could obliterate tumors due to their innate properties so that their heritable matter would not require genetic manipulation like virus forms adenovirus, herpes or polio. Furthermore, they do not integrate their heritable matter inside genome of the host cell hence one need not be apprehensive that these parvoviruses could cause accidental augment in growth eliciting genes.

Parvoviruses have a capability of passing through the blood-brain barrier; hence their intravenous administration is beneficial. Additionally, they are capable of reproduction in cancerous cells which is especially crucial for successful glioblastoma therapy with its disseminating development. Hence, the second cohort viruses would be capable of reaching and eliminating even those cancerous cells which have previously inhabited at some space from the main tumor.

Treatment options for brain cancer include surgery, radiation therapy and chemotherapy. In some cases radiation therapy alone may be enough to treat the tumor however in other cases it may be necessary to combine one or more treatments for the best results and the most successful outcome.

Surgery is generally the first choice for treatment in tumors that can be accessed in this way. The primary objective of surgery is to safely remove as much of the tumor as possible without causing damage to nearby healthy brain tissue. The larger amount of the tumor that can be removed the better the chances of success. In some cases this is not possible and only part of the tumor may be removed. While this may improve the problem other methods of brain cancer treatment may also be needed. In cases where removal is not an option your doctor may take a biopsy of the tumor in an effort to identify its type and thus determine the best course of future treatment attempts.

Chemotherapy is a method of treatment in which drugs are used to slow the growth of cancer cells in addition to preventing them from dividing and destroy as many of the cancerous cells as possible.

Radiation therapy in some cases is the only treatment that is feasible especially when the tumor is in a location that makes surgical access difficult or impossible. In this type of treatment powerful energy beams are projected into the affected area in an effort to destroy the cancerous cells and prevent the tumor from spreading. This method is often used in individuals who cannot choose surgery as a viable option and is sometimes used following surgery to target any cancerous cells that may remain. This is a local therapy meaning it only affects cancerous cells and has no effect on healthy cells.

There are several procedures or treatments that may be necessary prior to surgery being performed. You may need to be given a course of anti swelling drug such as dexamethasone or a drug to prevent seizures like carbamazepine. If you have a large amount of fluid around the brain a shunt may be inserted to drain the excess fluid.

Which brain cancer treatment is used varies from one person to the next because no two people are alike. Two individuals with the same size, location and type of brain cancer may receive very different treatments. This is largely because what works well for one person may not work so well for someone else. Your doctor will discuss which treatments are most likely to be the safest and most effective choices for your individual circumstances after diagnosis has been made and stage and type have been determined.

Some of the most common symptoms that may be noticed in association with brain cancer include motion sickness, dizziness, frequent loss of balance, seizures, changes in personality or behavior, memory loss, headaches, nausea, vomiting and changes in how a person thinks or talks. Other things that may be affected by brain cancer include speech, hearing and sight.

In order for these symptoms to be properly diagnosed it is necessary to consult your family’s health care provider for further evaluation and testing. These occurrences may not be brain cancer symptoms at all but it is important to see a doctor in order to determine the cause of any symptoms you may encounter.

Once brain cancer has been diagnosed and the severity has been determined as well as what areas or affected it will be time to discuss treatment options. Although there are several treatment options available to treat brain cancer there are several factors that may be used in order to decide which one is best for each individual. Some of these factors will include the person’s general health, the stage of the cancer, what areas are affected by the cancer and how far it has spread. Other factors that may also be considered are age and personal preference based on each individual case.

There are several treatment options that may be considered in treating brain cancer. Some of these options may include chemotherapy, radiation therapy or surgery. In most cases surgery is the most commonly chosen method of treatment because it is often the best way to be sure that all of the cancer has been removed. In cases where surgery is not possible chemotherapy or radiation therapy may be used. There may also be cases where more than one of these treatments is used in order to prevent the return of the cancer or tumors.

Depending on the type of brain cancer involved there may be no visible brain cancer symptoms. In these cases it is often hard to detect this disease and it advances without detection. It is very important that any changes in personality, behavior and motor function be noted and brought to the attention of a doctor promptly. Early detection of brain cancer is very important and can mean the difference between life and death.

If you experience any unusual behaviors or other symptoms that may be associated with brain cancer seek the advice of your doctor as soon as possible. Brain cancer is treatable when detected early enough. Even if your symptoms are completely unrelated to brain cancer it is much better to know sooner rather than later if there is a problem.

Studies have shown that brain cancer often affects more men than women putting men at an increased risk of developing this cancer.

There seems to be a higher risk of brain cancer within the Caucasian race and less occurrences in other races.

Brain cancer or brain tumors are most often found in people over the age of seventy years. When they are discovered in children it is usually in children under the age of eight years.

Although it has not been determined that one of the brain cancer causes is heredity it has been suggested that if someone in your family has had some kind of brain cancer or tumor it may increase your risk of developing brain cancer.

Being exposed to radiation or certain chemicals may put you at an increased risk for developing brain cancer. Some of the chemicals believed to increase this risk include formaldehyde, vinyl chloride and Acrylonitrile. These chemicals are most often found in factories of the industrial nature such as those used in the production of plastic and textiles.

In addition to these suggested risk factors scientists are also researching the possibility that cell phone usage may increase the risk of developing brain cancer or tumors though no concrete evidence has yet been found to support this claim.

There are several symptoms that may be noticed in individuals with brain cancer or tumors however not everyone will exhibit these symptoms. Some people with brain cancer have no symptoms at all until the very late stages. If you do experience symptoms associated with brain cancer you should seek medical advice promptly in order to rule it out or be diagnosed at the earliest possible stage. Some of the symptoms that you should be aware of include headache, nausea, vomiting, seizures, dizziness, clumsiness, changes in vision, sight or speech, changes in behavior and personality and loss of appetite or fatigue.

These risk factors are not brain cancer causes and being in an increased risk group does not mean you will develop brain cancer. It only means that you may have a slightly higher risk of developing this type of cancer than other people who may not be part of the same risk groups as you. Every person is different on the inside as well as the outside and what affects one person may not affect another. For this reason testing is available to determine the presence of brain cancer and brain tumors and if you experience any of the symptoms or any others that you cannot explain it is important to be tested in order to catch it early.

All types of malignant or cancerous brain tumors are considered life threatening, however not all benign or non cancerous tumors are as dangerous. Although both types of tumors can produce serious complications and symptoms benign tumors are generally only life threatening when they block vital systems such as arteries and veins.

It is rare for primary brain cancer to spread past the central nervous system and in most fatal cases death is caused by the tumor growing out of control within the skull and running out of room.

Metastasized or secondary brain cancer generally represents a primary cancer elsewhere in the body in very advanced stages. For this reason the mortality rate for this type of brain cancer is usually quite high. The most common cancers that spread to the brain are breast cancer, melanoma, renal cell carcinoma and colorectal cancer.

In addition to the different brain cancer types there are many types of tumors that may be associated with primary brain cancer.

Gliomas are tumors that form in the glial cells which work to protect important parts of the brain. These are often the most frequent brain tumors found in the adult population. Gliomas are broken down into different categories in relation to what types of brain cells they affect.

• Astrocytoma cells are star shaped cells that help to protect the neurons of the brain. Although cancer in these cells can spread to other parts of the brain it is rare for them to move outside the central nervous system. Cancer of these cells is separated in grades determined by the speed of progression.
• Oligodendroglioma cells produce myelin which is a fatty substance the makes a protective coating around nerve cells. Cancer of these cells are most commonly found in individuals over the age of 45.
• Ependymoma tumors affect the cells that line the passage which carries cerebrospinal fluid through the brain and spinal cord also known as ependymal cells. Although these are a rare form of tumor they are more common in children and in most cases do not spread past the ependyma.

Meningiomas affect the tissue that protects the brain and spine known as the meninges. Although these can occur at any age they are more common in those over the age of 65. These generally do not create symptoms and are slow growing. Most of these are discovered by accident.

Schwannomas or acoustic neuromas affect the nerve cells that are responsible for hearing. These types of tumors usually respond well to surgery.

It is important to know the brain cancer types in order to know which treatment will be best suited and more effective. If you have exhibited any of the symptoms associated with brain cancer you should seek medical treatment and begin testing promptly.

Early symptoms of brain cancer may include things like difficulty walking, frequent loss of balance, difficulty talking or hearing, nausea, loss of appetite, memory loss, weakness, changes in eyesight, vomiting, headaches and motion sickness. Some other symptoms that may be noticed are changes in a person’s alertness, personality or even mental capacity.

These symptoms alone however are not conclusive in diagnosing brain cancer because most if not all of these symptoms can also be indicative of other less serious health issues. It is important when encountering these or any other symptoms that a health care professional be consulted so that proper testing can be performed.

Not all individuals will demonstrate or show early symptoms of brain cancer. In these cases it is very important that any changes in behavior or personality be noted and discussed with your doctor. Even if these are not related to brain cancer there could be another problem that needs attention.

Because many of these symptoms can be caused by other health conditions there are other tests that may be performed in order to determine the presence of brain cancer. Some of the most common tests include CT scans, MRI or magnetic resonance imaging as well as white blood cell counts and microscopic examination of cerebrospinal fluid. In some cases a biopsy may be used to diagnose brain cancer.

After the initial diagnosis of brain cancer has been made the next step is to determine how much of the brain is affected and if it has spread to any other areas. This is an important process as this information is necessary to determine what treatment will be most effective.

After brain cancer has been diagnosed and stage has been determined your doctor will discuss treatment options with you. Several things are considered when determining the treatment of brain cancer.

The most common treatment of brain cancer is to remove the area that is affected through surgery. This is done by removing the part of the brain that contains the tumor. In cases where this is not possible other treatment options may be used such as chemotherapy and radiation treatment. In some cases all of these treatment methods may be used in combination to ensure that the cancerous tumor does not return.

It is imperative to seek medical attention at the first sign of any of the early symptoms of brain cancer. The earlier this disease is detected and diagnosed the better the chances of treatment being successful.
