For most patients, surgery will be necessary for successful brain tumor treatment. UNC Neurosurgery offers expertise and cutting edge technology when it comes to the surgical treatment of brain tumors. Our neurosurgeons examine and treat many different types of brain tumors, including pituitary tumors, in patients of all ages.
Common signs of a brain tumor in adults include frequent and severe headaches, dizziness, nausea, vision difficulty, seizures, confusion, and balance problems. If you are experiencing any of these symptoms, please contact your primary care provider. A neurological exam and medical imaging, such as an MRI or CT scan, will be used to confirm the presence of a brain tumor.
UNC belongs to three brain tumor consortia: the Brain Tumor Trials Collaborative (BTTC), the Alliance (Alliance for Clinical Trials in Oncology), and CERN (Collaborative Ependymoma Research Network). UNC also has a robust brain tumor research program with over a dozen labs dedicated to the diagnosis and treatment of brain tumors. Learn more about brain tumor research at UNC Medical Center.
Treatment of a brain tumor is determined by several factors. The size, type, and location of the brain tumor are all considered when our multidisciplinary brain tumor team develops a treatment plan for each patient.
The Department of Neurosurgery plays a key role in UNC’s multidisciplinary Brain Tumor Program. Our neurosurgeons partner with colleagues from neuro-oncology, radiation oncology, neuropathology, neuroimaging, neuropsychiatry, and supportive care to provide the best possible brain tumor treatment for our patients. We strive to individualize each patient’s care by using a team approach to develop an ideal treatment strategy.
During surgery, your neurosurgeon will try to remove as much of the brain tumor as safely possible, with the goal of complete removal. Your neurosurgeon will discuss the benefits and risks of brain tumor surgery with you during a consultation visit.
In. cases where surgical removal of the tumor is not possible, a procedure called a stereotactic needle biopsy may be performed to collect a tissue sample of the tumor.
A craniotomy is a common surgery used by our neurosurgeons to treat diseases and abnormalities of the brain, including brain tumors. During the procedure, part of the bone from the skull is removed to access the area of the brain with the tumor. Surgeons will remove the brain tumor and collaborate with neuropathology to get as much patient specific information as possible from the tumor tissue.
In some cases, the brain tumor causes a buildup of cerebrospinal fluid in the brain, which can cause pressure on the brain. If this occurs, your neurosurgeon may recommend surgically placing a shunt to relieve pressure and safely drain the excess fluid away from the brain.
Embolization may be performed on a brain tumor patient prior to the removal of a brain tumor to cut off blood supply to the tumor, thus reducing blood loss during removal and making the surgical site easier to access.
Endoscopic brain surgery is a minimally invasive procedure used to treat brain tumors. Because this procedure is minimally invasive, patients experience a faster recovery and reduced risk of damage to the brain and a reduced risk of side effects.
In malignant (cancerous) types of tumors, radiation is often used with our without an open surgery. There are many types of radiation with some being very focused in one area (Cyberknife), and your surgeon and radiation oncologist will work with you to decide on the best treatments for you.
Rehabilitation may be necessary for some brain tumor patients following their brain tumor surgery. Talk with your neurosurgeon and surgery team to find out which brain tumor surgery is right for you.
We offer weekly adult neurosurgery clinics for brain tumor patients in Chapel Hill, NC. Call 984-974-4175 to schedule an appointment.
UNC Neurosurgery also offers pediatric brain tumor treatment.
