If your primary care doctor suspects you have a brain tumor, you may be referred to a specialist who is trained in treating brain and nervous system disorders (neurologist). Your doctor may recommend a number of tests and procedures, including:
Imaging tests. Magnetic resonance imaging (MRI) is often used to help diagnose brain tumors. In some cases, a dye (contrast material) may be injected through a vein in your arm during your MRI study to help show differences in brain tissue.
A number of specialized MRI scan components â including functional MRI, perfusion MRI and magnetic resonance spectroscopy â may help your doctor evaluate the tumor and plan treatment.
Other imaging tests may include computerized tomography (CT) scan and positron emission tomography (PET).
Collecting and testing a sample of abnormal tissue (biopsy). Depending on the location of the glioma, a biopsy may be performed with a needle before treatment or as part of an operation to remove the brain tumor.
A stereotactic needle biopsy may be done for gliomas in hard-to-reach areas or very sensitive areas within your brain that might be damaged by a more extensive operation. During a stereotactic needle biopsy, your neurosurgeon drills a small hole into your skull. A thin needle is then inserted through the hole. Tissue is removed through the needle, which is frequently guided by CT or MRI scanning.
The biopsy sample is then analyzed under a microscope to determine if it's cancerous or benign.
A biopsy is the only way to definitively diagnose a brain tumor and give a prognosis to guide treatment decisions. Based on this information, a doctor who specializes in diagnosing cancer and other tissue abnormalities (pathologist) can determine the grade or stage of a brain tumor.
The pathologist will also examine the physical appearance and growth rate of your biopsy sample (molecular diagnosis). Your doctor will explain the pathologist's findings to you. This information helps guide decision-making about your treatment plan.
Little research has been done on complementary and alternative brain tumor treatments. No alternative treatments have been proved to cure gliomas. However, complementary treatments may help you cope with your brain tumor and its treatment. Talk to your doctor about your options.
Some complementary treatments that may help you cope include:
A diagnosis of a brain tumor can be overwhelming and frightening. It can make you feel like you have little control over your health. But you can take steps to cope with the shock and grief that may come after your diagnosis. Consider trying to:
Find someone to talk with. Find a good listener who is willing to listen to you talk about your hopes and fears. This may be a friend or family member. The concern and understanding of a counselor, medical social worker, clergy member or cancer support group also may be helpful.
Ask your doctor about support groups in your area. Or check your phone book, library or a cancer organization, such as the National Cancer Institute or the American Cancer Society.
