Types of Benign Brain Tumors

At Rush Radiosurgery, we treat a variety of malignant and benign brain tumors with the state-of-the-art TrueBeam STx® technology. While a brain tumor diagnosis can be scary, many tumors found in the brain may be benign. Unlike malignant tumors that are cancerous, benign tumors are non-cancerous growths of cells that cannot spread or invade other parts of the body.

Read more about the different types of benign tumors below:

  • Meningioma: Most meningiomas are benign tumors that arise from the membranes surrounding the brain and spinal cord. In many cases, meningiomas grow slowly, meaning that depending on its location, a meningioma may reach a large size before it causes any symptoms.
  • Acoustic Neuroma: Also called a vestibular schwannoma, an acoustic neuroma is a rare, slow growing benign tumor of the balance and hearing nerves. While the tumor does not invade the brain, it can begin to push against the brain as it grows over a period of years, potentially causing vision or balance problems among the first symptoms. Visit the Acoustic Neuroma Association website to find more information and resources for this type of tumor.
  • Pituitary Adenoma: One of the most common types of benign brain tumors, it is said that up to 10 percent of people will develop a pituitary adenoma at some point in their lifetime. Because pituitary tumors are usually found on the front part of the pituitary gland (the gland that produces hormones), about 50 percent of these tumors produce an excess amount of one hormone, creating a hormone imbalance in people affected.

Treatment of brain tumors varies based on the location and size of the tumor. For surgically inoperable or hard to reach tumors, a noninvasive treatment option can be an alternative. Rush Radiosurgery’s TrueBeam STx technology treats brain tumors using stereotactic radiosurgery, a painless, noninvasive technique that targets tumors with pinpoint radiation beams, minimizing radiation exposure to surrounding healthy tissue and decreasing the likelihood for side effects.
