Brain Cancer Awareness. It is my desire that no one should be aware of this disease, or anything else.
Pay attention to all forms of cancer are dangerous and can happen to anyone. Please pray for my friend, he is diagnosed with fourth time.I have more info on my website.
Symptoms and diagnosis
brain tumor takes up space in the skull and may interfere with normal brain activity. This may increase pressure on the brain, the brain shift or slide it on the head and / or invade and damage nerves and healthy brain tissue. Location of a brain tumor affecting the types of symptoms that occur. Identify the presence of a brain tumor is the first step in determining treatment.

1.What are the symptoms of a brain tumor? A brain tumor may have a variety of symptoms from headaches stroke. Different parts of the brain control different functions, so symptoms depend on tumor location. Brain tumors are a great mimics of other neurological disorders, and many of the most common symptoms may indicate other medical conditions. The best way to find out if you or someone you know has a brain tumor, the doctor will make a type of brain scan called an MRI scan or CT scan, called Sometimes it is hard to know whether CT or MRI should be done if someone you know has some of the symptoms and signs listed below, but it is important to note that these studies will usually establish whether a brain tumor is behind them. If you’re really worried, make sure to discuss your concerns with your doctor.
The symptoms of brain tumor are as follows: A new impetus for adults
gradual loss of focus or sense of movement of an arm or leg
? Unsteady or balance, especially if the headache is
? Loss of vision in one or both eyes, especially if the loss of peripheral vision
? double vision, especially as it relates to headaches
? Without hearing loss or dizziness
? Speech difficulty of gradual onset
Other symptoms may include nausea and vomiting are the most difficult in the morning, confusion and disorientation and memory loss.
The following symptoms are usually not caused by a brain tumor, but it can sometimes be:
Headache: Although headaches are probably the most common symptom of brain tumor, the majority of headaches – even persistent or severe headaches – it is not cancer. But some types of headaches are of particular concern. Constant headache that is worse than the morning in the afternoon, a persistent headache accompanied by nausea or vomiting, or headache accompanied by double vision, weakness or numbness all suggest a possible tumor.
change in behavior? Development of “I do not care” attitude, memory loss, loss of concentration, and general confusion may all be subtle signs. In this case, the neurologist may be an important step in the evaluation, but CT or MRI can also help.? Infertility or abnormal termination of menstruation (also known as amenorrhea)
? Concerns that seems to be caused by other diseases or concerns: seizure caused by a depression or a discovery that seems to subarachnoid haemorrhage (a type of stroke) can actually cause cancer.
If you are worried that you or someone you know might have a brain tumor, consult your doctor. If symptoms persist, an MRI or CT scan to the correct diagnosis. Early detection and treatment can improve survival. With grateful for confirmation of the content offered by Peter MCL.

2.How to have a brain tumor diagnosed? Identification of a brain tumor usually involves neurological examination, brain scan, and / or analysis of brain tissue. Doctors use diagnostic information to be classified as least aggressive tumors (benign), the most aggressive (malignant). In most cases, the tumor cell type of origin of the name or location in the brain. Determine what type of cancer can help doctors determine the most appropriate course of treatment.
neurological examination is a series of tests to measure the patient’s neurological and physical and mental alertness. If the answers to the exam is normal, your doctor may order brain scan, or refer the patient to a neurologist or a neurosurgeon, who ordered the brain scan. is a brain scan image of internal structures in the brain. A specialized machine will look the same way a digital camera photo. Using information technology, prepare the brain scan images photographing it from various angles. Some types of scans use a contrast agent (or the opposite color), allowing the physician to see the difference between normal and abnormal brain tissue. Contrast medium is injected into a vein and flows into the brain tissue. Abnormal or diseased brain tissue absorbs more color than the normal healthy tissue. The most common scans used for diagnosis are as follows:
MRI (magnetic resonance imaging) is a scanner that uses magnetic fields and computers to take pictures cerebral film. It does not use x-rays. This allows images of different planes, which allows doctors to create a three dimensional image of the tumor. MRI detects signals from normal and abnormal tissues and provides clear images of most tumors.
CT or CAT Scan (CT) combines sophisticated x-ray and computer technology. CT may be a combination of soft tissue, bone and blood vessels. CT images can be set for certain types of cancer, as well as help detect swelling, bleeding, and bone and tissue calcification. Normally, iodine contrast agent used during the CT scan. PET scan (positron emission tomography) provides a picture of brain activity, rather than its structure by measuring the rate at which the tumor absorbs glucose (sugar). The patient is injected deoxyglucose, which is labeled as radioactive markers. PET scan measures the brain activity and sends this information to your computer, creating a vivid picture. Doctors use PET scans to see the difference in scar tissue, recurring tumor cells, and necrosis (cells destroyed by radiation therapy). There are some disadvantages of these diagnostic tests, however. Please see What should I know about the diagnostic tests? For more information. biopsy is a surgical procedure in which tissue sample is taken and examined under the microscope, the tumor site. The biopsy gives information about the types of abnormal cells in the tumor. The aim is to discover the type and extent of a biopsy of the tumor. A biopsy is the most accurate method to obtain the diagnosis. open biopsy is done under the craniotomy. Craniotomy involves removing a piece of the skull to access the brain. After tumor resection (complete removal) or debulked (partially removed), bicycles are generally laid back. A closed biopsy (also called a needle or stereotactic biopsy) may be made when the tumor is the area of ??the brain, which is difficult to achieve. Closed biopsy, neurosurgeon drilled a small hole in the skull, and walking a thin hollow needle to remove the tumor tissue sample. If the sample is collected, the pathologist examines tissue under a microscope, and writes the report contains an analysis of brain tissue pathology. Sometimes the pathologist may not be able to make an accurate diagnosis. This may be due to more than one instance of the same tumor cells in a tumor. In some cases, tissue is sent to another institution for further analysis. Up
3 What else should I know about the diagnostic tests? Because MRI uses a magnetic field, people who have metal implanted in your body in any form should let your doctor know to give up planning procedures. MRI, these patients may not be possible because of a strong magnetic field may damage some types of implanted medical devices. Patients should notify their physician if they are cardiac pacemakers, heart monitors, surgical staples, or facial tattoos.
In a standard MRI, the patient is located in a narrow table that slides through the long, cylindrical tube with a narrow aperture. Although the patient’s room is NOK inside the cylinder, the patient can not move. Scan takes about 15-45 minutes. During scanning, the patient will hear a loud banging noise that is caused by the electronics maker. Patients may request earplugs to reduce noise. Some people feel claustrophobic MRI in advance and ask for a sedative to relax. Other people ask for an open MRI. open MRI machine is a cylinder, so that the patient is not included. The procedure takes about 45 minutes. There is some debate among physicians on the quality of MRI images over standard open or closed MRI. Contrast agents can cause allergic reactions in some patients. Gadolinium, a contrast agent used with MRI, which can cause temporary headaches <-! Next Page -> but has no other known side effects. Iodine is most commonly used contrast medium for CT scanning. If you know you are allergic to iodine, your doctor. Allergic reactions may include rash, warm feeling, or, in rare cases, difficulty in breathing. CT scans involve exposure to ionizing radiation, which is known to cause cancer. This is a concern about people who may need more CT scans, and children, because they are more sensitive to radiation than adults. It is reasonable that people who have had frequent x-rays and the parents keep their children’s brain tumors in the history of x-ray. This information may help physicians make informed decisions and to reduce the radiation dose. Up
4.How pathology report is used to diagnose a brain tumor? The pathology report contains the analysis time, craniotomy, or brain tissue by needle biopsy. Pathologist examining tissue under a microscope. Additional tests or analysis of tumor tissue can be made. If the pathologist writes pathology reports, providing information necessary for the diagnosis of tumor type.
