What is a brain tumor?
Primary brain tumors develop when the normal, healthy cells inside the brain begin to grow and function differently. These cancerous cells build up, forming a mass called a tumor, and can vary in degrees of aggressiveness (called grades).
Grades I and II are considered lower-grade (less aggressive) tumors. These types of tumors tend to grow more slowly and are less likely to affect nearby tissues. Grades III and IV are higher-grade (more aggressive) tumors that tend to grow more quickly. These types may leave the brain and travel into nearby tissues, often requiring a higher level of care and treatment.
Secondary brain tumors, also known as metastasis brain tumors, are tumors that grow within the brain after spreading from another area of the body, such as the lung, bowel, kidney, breast or prostate.
Common types of primary brain tumors include:
- Gliomas – These tumors occur in the brain and spinal cord. Gliomas are the most common type of brain tumor and their severity varies depending on their location and rate of growth.
- Astrocytoma tumors – These tumors can form on the brain or spinal cord. While they are cancerous, they can either grow very slowly or aggressively. Treatment for astrocytoma tumors depends on their aggressiveness.
- Ependymoma tumors – These tumors can form on either the brain or the spinal cord, but they’re more common in the spine for adults. They form in the ependymal cells that make cerebrospinal fluid — a fluid that supports your brain. These tumors can be benign (non-cancerous) or malignant (cancerous).
- Oligodendroglioma tumors – Originating in the brain, these tumors are a rare type of glioma that usually form in the front part of the brain. While it’s extremely rare, they can also form on the spine.
- Medulloblastoma – This is the most common type of malignant brain tumor and sometimes spreads to other parts of the brain and spinal cord. These tumors typically grow from the cerebellum (small brain), which can cause a buildup of fluid, putting pressure on the brain (hydrocephalus).
- Central nervous system (CNS) lymphoma – CNS tumors are rare, malignant tumors that form from lymph tissues in the brain or spinal cord. Sometimes, these occur when lymph tissue spreads to the brain or spine from other parts of the body.
- Meningioma tumors – These tumors grow in the meninges (membranes that surround the brain and spinal cord) and can compress nerves and vessels. They are the most common type of tumor to develop in the head.
- Pituitary tumors – Tumors can form on your pituitary gland, which produces hormones that affect growth and the function of glands throughout the body. When a pituitary tumor forms, it can either cause the production of too many hormones or block hormone production.
- Schwannoma – A schwannoma occurs when a tumor forms on the tissue surrounding the nerves. Often, this type of tumor is not cancerous.

Symptoms of brain tumors
The symptoms of a brain tumor can be similar to many other conditions and include:
- Balance issues
- Increased head pressure
- Hearing problems
- Loss of appetite or difficulty eating
- Memory problems
- Nausea or vomiting
- Numbness or weakness in the arms or legs
- Personality changes
- Changes in hearing
- Seizures
- Severe or frequent headaches
- Slurred speech
- Sudden vision problems
- Trouble swallowing
Having any of these symptoms doesn’t mean you have a brain tumor. However, it’s important to make an appointment with your doctor to rule out any health issues.
Brain tumor risk factors
Often, a brain tumor’s cause is unknown. However, certain risk factors can increase your risk of developing a brain tumor. These include:
- Age: While brain tumors can develop at any age, the risk is higher for adults 65 and older and children.
- Gender: Men are more likely to develop a brain tumor than women.
- Family history: If you have a family member who’s been diagnosed with a brain tumor, you’re at a higher risk. About 5% of brain tumors may be linked to genetics.
- Health history: Certain aspects of your health history, including seizures and head injuries, can increase your chance of developing a brain tumor.
- Other risk factors: Other factors that can raise the risk of developing a brain tumor include:
- Previous radiation exposure
- Certain infections, viruses and allergens
Diagnosing brain tumors
Detecting a brain tumor is the first step in treating it — so you can get back to living the life you love.
Some of the diagnostic tests your doctor may perform to test for a brain tumor include:
- Magnetic resonance imagining (MRI) – MRIs use powerful radio waves and magnets to create detailed, 3D images of the brain.
Most MRIs operate at a strength of 1.5 Tesla (a unit that measures the strength of a magnetic field). Our team uses 3 Tesla MRI technology, which operates at twice the strength of traditional MRI scanners.
This technology provides highly detailed images of the brain, which allows us to treat tumors more accurately and better than ever.
- Computerized tomography (CT or CAT) scans – CT and CAT scans use X-rays to obtain cross-sectional images of the brain.
- Spinal tap – If you have this procedure, your doctor will remove fluid from your spine to help make a diagnosis.
- Bone scans – Bone scans are nuclear imaging tests that help your doctor make a diagnosis.
- Biopsies – During a biopsy, your doctor removes a small sample of tissue with a thin needle or during a surgical procedure. Then they examine the tissue under a microscope to determine if it contains cancerous cells (also called malignant cells).
Brain tumor care at Geisinger
While our specialists are experienced in treating even the most complex brain tumors, our entire team works together to help you fight your cancer — every step of the way.
Our brain tumor specialists are dedicated to providing innovative treatments and personalized care. We offer:
When surgery is performed, our team uses minimally invasive techniques whenever possible alongside live imaging and neurological monitoring. Our surgeons are also trained in minimally invasive laser ablation surgery, using a laser probe during brain tumor surgery to burn rather than remove a tumor. Minimally invasive and laser ablation procedures often have a faster recovery time compared with traditional surgery.
Our surgery team works hard to plan as much as possible before surgery in order to provide you with a safe experience, faster recovery and a prompt return home.
Radiation oncology uses radiation to control or destroy harmful cancer cells.
Our board-certified cancer doctors and highly skilled clinical team deliver conventional radiotherapy treatments that include:
- External beam radiation, which uses special technology to send radiation to the tumor from outside the body.
- Internal radiation, which targets the tumor using safe levels of radiation.
- Intensity-modulated radiation therapy (IMRT), which uses a 3D image of the tumor to deliver high-precision radiotherapy that fits the tumor’s exact outline.
- Image-guided radiation therapy (IGRT), which is used to treat cancers in areas of the body that move during and between treatments. This includes cone beam CT scans to accurately view the tumor and target it during treatment.
- Stereotactic body radiation therapy (SBRT), which uses precise beams of radiation to focus high doses of radiation shaped just around the tumor, with very little damage to surrounding healthy tissues.
CyberKnife® robotic radiosurgery is a non-invasive treatment for tumors that are hard to reach or inoperable. This robotic therapy targets complex tumors — including cancerous and non-cancerous tumors — by delivering high doses of targeted radiation safely, anywhere in the body. And it’s offered at the Frank M. and Dorothea Henry Cancer Center at Geisinger Wyoming Valley Medical Center in Wilkes-Barre.
No incisions involved. So you have quicker treatments, less pain and faster recovery. Learn more about CyberKnife.
Chemotherapy is a drug-based treatment designed to slow the growth of or shrink tumors and can be given through an IV or taken in pill form.
Your chemotherapy may be given:
- Before your surgery, to attempt to reduce the size of the tumor
- After your surgery, to destroy any cancer that still remains in the area and reduce the chances of the cancer coming back
- Along with radiation therapy, which is called chemoradiation or chemoradiotherapy
Because of the blood-brain barrier (the brain’s extra layer of protection that fights infection), traditional chemotherapy is not used to treat brain cancer. Our specialists use the latest laser therapy techniques to deliver targeted chemotherapy to better treat brain tumors. This includes intrathecal chemotherapy, which delivers chemotherapy through cerebrospinal fluid instead of through your bloodstream.
