Glioma
In this condition factsheet:
Diagnosing Glioma
Doctors use a number of techniques or procedures to determine if a person has a brain tumour. First, a doctor performs a physical examination and asks about the person's medical history. If a brain tumour is suspected, the person will likely be referred to a neurologist. The neurologist will likely perform neurological tests to determine how the nerves in the brain and spinal cord are working. Other tests used may include:
- blood tests
- chest X-ray
- computed tomography (CT or CAT) scan (if a tumour is present, it will show the location)
- magnetic resonance imaging (MRI) (not always performed)
- electroencephalogram (EEG)
- a tissue sample from the tumour to determine the type
For low-grade astrocytoma tumours, magnetic resonance imaging (MRI) is often the best way to see the tumour. High-grade astrocytoma tumours are best viewed with a CT scan. The grade of the tumour can also be determined by looking at the cells under a microscope.
If a brain tumour is diagnosed, the best method of treatment must be determined. It should be determined whether it is safe for the person to drive.
Treating and Preventing Glioma
People with gliomas often receive a combination of different types of treatment for the best chance of recovery. Possible treatments include chemotherapy, radiation therapy, targeted therapies, and surgery.
Medications are useful in the treatment of glioma. Antiepileptic medications help reduce the risk of seizures. Chemotherapy, which uses a combination of powerful medications, helps damage or kill cancer cells. Unfortunately, chemotherapy medications also affect healthy cells in the body which may lead to side effects such as hair loss and vomiting. Corticosteroid medications may be recommended to reduce the swelling around a brain tumour.
Surgery is recommended in most cases to remove the tumour. The surgeon may decide to remove part of or the entire tumour depending on its location. If the tumour is on or close to the brain stem, surgery becomes more challenging. Surgery may also be done to relieve the pressure inside the brain.
Radiation therapy uses X-rays to destroy cancer cells in the tumour. Radiation therapy may damage healthy tissue around the tumour but doctors try to limit this damage as much as possible. Radiation can be done initially on its own, or if disease comes back after surgery.
Targeted therapies can be used to treat some forms of glioma. These therapies target and inhibit certain molecules which tell cancer cells to grow and divide. Just like many other cancer therapies, there can often be side effects, which vary depending on which targeted therapy drug is used. The most common side effects include:
- fatigue
- flu-like symptoms
- low blood cell counts
- nausea or vomiting
- skin issues such as rash
- vomiting
Some people also choose to enroll in a clinical trial for experimental medications or use complementary and alternative therapies (e.g., herbal preparations, reflexology, acupuncture, and Chinese medicine). Ask your doctor about what clinical trials are being offered that may suit your cancer treatment needs and what complementary therapies are available.
Generally, people choose to use complementary or alternative therapies along with the treatment recommended by their doctor.
To reduce your risk of developing different forms of cancer, make healthy choices every day. Some of these choices include:
- stopping smoking
- eating a healthy diet
- exercising regularly
- maintaining a healthy weight
- limiting alcoholic drinks
- reducing exposure to the sun's damaging rays and tanning beds
- minimizing exposure to chemicals and, if needed, handling chemicals safely and as instructed
