Know About Brain Tumor Before Consulting a DoctorBY: Ritu Choudhary | Category: Brain Tumors | Submitted: 2010-07-03 18:44:16
The information on the topic of brain is designed to complement the discussion with your doctor. This general information can not always do justice to each individual; this depends on the criticality of the patient. Do you have after reading this information any further questions, and then you can ask your doctor. The text is based on information from the world Cancer Society. Signs of Brain Tumors The symptoms that can occur with a brain tumor are of three types: exit signs, epilepsy and complaints by an increase in pressure within the skull. What failure symptoms arise depends on the location of the tumor. Examples are paralysis, with a tumor in the left hemisphere, problems with language, such as inability in pronouncing words, or not understanding what others say. Also, there are memory related problems. If the tumor is found in the brain, behavioral changes can occur. Few common behavioral changes are dullness (laziness) and in-difference, irritability and moodiness. A tumor in the brain sometimes interferes with the brains ability to read and see. A seizure is often the first sign of a brain tumor. Pain attack is caused by irritation of the nerve cells in the brain. An epileptic seizure can be very light, possibly a few shocks in a hand or a brief 'absence'. But it is also possible that a person suddenly becomes unconscious or has violent shocks in arms and legs. Such a violent attack could be accompanied by unintentional urine loss and the tongue bite. The attack is virtually always self-limiting. The pressure inside the skull increases when a tumor grows. Furthermore, moisture often accumulates around the tumor (edema) and prevents the flow of cerebral fluid. This gives symptoms as persistent headaches and sometimes nausea and vomiting. As the pressure increases significantly drowsiness occurs. Pressing of the optic nerve due to tumor and pain can cause blurred or double vision. All these symptoms can also occur with other disorders. It is therefore wise for patients to consult a specialist whenever they see such symptoms. Forms of Brain Tumor Brain tumors are different forms. A brain tumor may arise in the brain itself (intra-cerebral tumor) or in the other tissues within the skull (additional cerebral tumor). An additional cerebral tumor can be dangerous to main brain if it presses against the brains. An example of a more cerebral tumor was meningitis, a tumor that originates in the meninges. Additional Cerebral tumors are less common than intra-cerebral. Intra-cerebral tumors are divided into primary and secondary tumors. A primary tumor is a tumor that arose directly into brain tissue. A secondary tumor is a metastasis of cancer elsewhere in the body, such as a chest or lungs. Such a secondary tumor is also called as brain metasis. Primary intra-cerebral tumors called glioma is the most common. A glioma is based on the support cells in the brain, also called glial cells. Other more rare brain tumors are ependymomas and medullablastoma. Diagnosis of Brain Tumor For symptoms that might indicate a disease of the brains, such as a brain tumor, doctors often refer to neurologists. They examine whether the overall health of brain and note the its functioning. The strength in the arms and legs, talking and sense of balance is also tested. When the neurologist suspects that there is a brain tumor, several other studies and tests are possible. The most common and important is CT scan, an MRI and an EEG. In a CT scan (computed tomography) are cross-sectional images of the brains are taken. These pictures illustrate the location, size and extension of a possible tumor in brain. MRI (Magnetic Resonance Imaging) is a study of magnetic fields and radio waves (not X-rays). EEG (electro-encephalogram) provides information about the functioning of parts of brain.
