What are the causes of brain tumors?
Brain Cancer FAQThe causes of brain tumors are not known. Brain tumors are not contagious. They can occur at any age, although they are most common in children 3-12 years old and adults 40-70 years old. Risk factors include working in industries such as oil refining, rubber manufacturing and drug manufacturing; other studies show chemists and embalmers have higher incidence of brain tumors. Researchers also are looking at exposure to viruses as a possible cause.

The Sam Harry Foundation - FAQNo one knows what causes brain tumors, although research is ongoing in this area. Inherited and genetic factors may play a role. Environmental factors and viruses may also be involved. Certain risk factors may increase the chance for developing a brain tumor. Workers in oil refining, rubber manufacturing, drug manufacturing, and chemists and embalmers all have a higher incidence than average in developing brain tumors. However, at the present time, there is no clearly defined risk factor.Related Questions
What are the symptoms of brain tumors?
Brain Cancer FAQThe symptoms depend on the size of the tumor and the location. Symptoms are caused by damage to vital tissue and by pressure from the tumor or swelling, which may happen if the tumor blocks the flow of cerebrospinal fluid.
Related QuestionsWhat are the types of brain tumors?
Brain Cancer FAQThere are primary and secondary brain tumors. Tumors that begin in brain tissue are known as primary tumors. Secondary tumors are when cancer spreads from another site to the brain, which is called metastasis. Brain tumors are classified by the type of tissue in which they begin. The most common brain tumors are gliomas. Astrocytomas 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.
Related QuestionsWhat are the treatments for brain tumors?
Brain Cancer FAQThe doctor develops a treatment plan to fit each patient, depending on the patient’s age and general health and the type, location and size of the tumor. Brain tumors are treated with surgery, radiation therapy and chemotherapy. Before treatment most patients are given steroids to reduce swelling. They may also be given anticonvulsant medications to prevent seizures. Surgery is the usual treatment for most brain tumors. To remove the tumor, the neurosurgeon makes an opening in the skull.
Related QuestionsJohns Hopkins Surgical Neuropathology: Frequently Asked Ques...Even though it seems as if there are two types of brain tumors, benign and malignant, there are close to one hundred tumor types. Furthermore one can divide brain tumors into primary and metastatic types. The primary brain tumors arise from the cells that make up the brain and spinal cord or the tissues covering the brain. The metastatic tumors spread from another body site to the brain, and by definition, are always malignant.Related Questions
How are pediatric brain tumors diagnosed?
Pediatric FAQA brain tumor diagnosis usually involves several steps, which can include a neurological examination, brain scan(s) and/or a biopsy. Should a child’s symptoms lead the doctor to suspect a tumor, a neurological examination will be given. This is a series of tests to measure the function of the child’s nervous system and physical and mental alertness. If responses to the neurological exam are not normal, the doctor may order a scan.
Related QuestionsHow are pediatric brain tumors treated?
Pediatric FAQThe standard treatments for brain tumors are surgery, radiation therapy, and chemotherapy. In some cases when the tumor is slow growing, the treatment team may delay surgery and use frequent scans to monitor the tumor's growth. Sometimes surgery alone will cure a brain tumor. In general, radiation and chemotherapy treatments are used as secondary or adjuvant treatments for tumors that cannot be managed using only surgery.

Pediatric FAQSome of the general symptoms of brain tumors in children are headaches; vomiting (usually in the morning and without nausea); unsteadiness or loss of balance; seizures; double vision or vision problems; decreased coordination; fatigue or sleepiness; weakness on one side of the body; increased size of the head; uncontrolled eye movements; irritability; and behavioral changes. Symptoms are often vague in children, especially in very young children who are not able to fully describe their symptoms.
Related QuestionsHow are brain tumors diagnosed?
Anatomy of the Brain: The Brain Tumor Program at University ...Brain tumors are diagnosed through a combination of physical exam and diagnostic tests. A neurological exam assesses both a patient's physical condition?balance, sensory abilities, and muscle movement, for example?and his or her mental status. Next, images of the brain are captured by scanning techniques such as magnetic resonance imaging (MRI) or computed tomography (CT). In some cases, a physician may order a cerebral angiography, which is an X-ray of the brain's blood vessels.
Related QuestionsDo brain tumors run in families?
Vanderbilt Brain Tumor Center - Frequently Asked QuestionsThere are rare cases where brain tumors can occur in families and have a known genetic link. Most brain cancers, however, occur in patients with no known family history of brain cancer. We generally do not recommend screening family members for brain tumors.
Related QuestionsCan brain tumors be removed completely?
Vanderbilt Brain Tumor Center - Frequently Asked QuestionsBecause brain cancers invade the normal brain, it is often very difficult to remove them completely. This is especially true with tumors of higher grade (grades III or IV). Usually, neurosurgeons attempt to remove as much of the tumor as is safely possible. When the tumor infiltrates into a critical brain area, it may not be possible to remove it completely.

Related QuestionsWhich therapies are used to treat brain tumors?
Treatment FAQSurgery is the primary form of treatment for brain tumors that lie within the membranes covering the brain or in parts of the brain that can be removed without damaging critical neurological functions. Because a tumor is likely to recur if any tumor cells are left behind, the goal of surgery is to remove the entire tumor whenever possible. Radiation therapy and chemotherapy are generally used as secondary or adjuvant treatments for tumors that cannot be managed using only surgery.
Related QuestionsWhat should I know about clinical trials for brain tumors?
Treatment FAQClinical trials are research studies that involve people. The studies are designed to determine the safety and side effects of new therapies, and the effectiveness of new and current treatments. Clinical trials usually undergo three phases before reaching completion. Each phase answers a question about the safety and effectiveness of the treatment being tested. Phase I trials test a treatment to determine a safe dosage and its side effects. Phase II trials test a treatment for its effectiveness.
