4 Common Types of Brain Tumors

More than 1.3 million Americans are living with brain tumors. While they’re not always cancerous, they are a daunting health concern — and if you or a loved one is experiencing worrisome symptoms, it’s normal to have questions.

Understanding the different brain tumors can help demystify this complex condition and give you insight into potential treatments. David A. Wiles, MD, a leading neurosurgeon in Chattanooga, Tennessee, offers the expertise you need.

Here are four common types of brain tumors and symptoms to watch out for.

1. Gliomas

Gliomas originate from glial cells, which are cells in your brain that support nerve cells. These tumors can form in various parts of your brain and spinal cord, and they are some of the most common brain tumors.

Subtypes include astrocytomas, oligodendrogliomas, and ependymomas. Symptoms may vary depending on the tumor's location but can include headaches, seizures, and neurological changes like weakness or sensory changes.

2. Meningiomas

The meninges are the protective layers surrounding your brain and spinal cord, and meningiomas are tumors that grow there. Meningiomas are often slow-growing and typically benign.

However, because of their location, they can cause significant symptoms depending on the pressure they put on surrounding brain tissue. Symptoms include headaches, changes in vision or hearing, and difficulty with balance or coordination.

3. Pituitary adenomas

Pituitary adenomas develop in your pituitary gland, a small but vital gland located at the base of your brain. Some pituitary adenomas are non-functional, which means they don’t cause symptoms. Others can cause hormone overproduction and a range of health issues, like hormonal imbalances, vision changes, and headaches.

4. Medulloblastomas

Medulloblastomas are a type of brain tumor that originates in your cerebellum, the region responsible for coordination and balance. Although they can affect anyone, they’re most common in children and young adults.

These tumors tend to grow rapidly and can cause symptoms like headaches, nausea, vomiting, and problems with balance and coordination. Sometimes, medulloblastomas can spread to other parts of the central nervous system.

Recognizing the potential symptoms of brain tumors

Brain tumors are fairly rare, but learning to recognize the potential symptoms is important for early detection and intervention. Schedule an appointment with a neurologist like Dr. Wiles if you experience symptoms, such as:

• Persistent, worsening headaches
• Unexplained seizures
• Unexplained changes in vision, hearing, speech, or motor function
• Memory problems, confusion, or changes in behavior or personality
• Nausea and vomiting, when accompanied by other neurological symptoms

We see patients of all ages living in Chattanooga, Bristol, Kingsport, and Johnson City, Tennessee. During your consultation, Dr. Wiles and our team do a thorough physical exam, ask questions about your symptoms, and review your medical history.

We may also order imaging tests, like an MRI or CT scan, to visualize your brain and identify any abnormalities that could indicate the presence of a tumor. Then, we discuss next steps.

Don’t wait to schedule an evaluation if you or a loved one experiences any concerning symptoms. Early intervention can significantly improve treatment outcomes, and we’re here to help you find the answers you need. Call our office at 423-459-9800 or request your first appointment online now.
