BrainTumors: FAQ and A Neurosurgeon's Answers

While we know popular medical drama TV shows like Grey’s Anatomy don’t reflect real life, how they portray brain tumors can lead to huge misconceptions.

To help set the record straight, Gwinnett Medical Center’s Michael Stechison, MD, PhD answers a few common questions, answered by. 

Dr. Stechison is not only one of the region’s most respected neurosurgeons, he’s been an educator and practitioner of neurosurgery since 1989 and is particularly known for his microsurgical treatment of brain tumors.

What are the symptoms of a brain tumor?

People who have benign tumors sometimes exhibit changes in their personality or behavior. Headaches can be common – but it is important to know that most people with headaches don’t have a brain tumor. Headaches associated with brain tumors often are worse in the morning and frequently are associated with nausea and vomiting. Other symptoms are new onset of seizures, weakness in an arm, leg or side of the body, visual disturbance or altered behavior. A rapidly growing malignant tumor is more likely to produce symptoms while a slow-growing benign (noncancerous) tumor may have no symptoms and may be discovered incidentally on a brain scan done for another reason.

What causes brain tumors?

Each year in the U.S., approximately 20 per 100,000 people (0.02 percent) will develop a primary brain tumor, which is a tumor that begins in the brain. The DNA of a cell is damaged through a combination of mutation and inherited faulty genetic copy, and the cell begins to divide uncontrollably, reproducing itself and becoming unresponsive to signals telling it not to divide. Secondary (metastatic) brain tumors occur when cancer cells spread to the brain from a primary cancer elsewhere in the body.

What risk factors might increase the likelihood of developing a brain tumor -- and is using a cell phone one of them?

Primary brain tumors have no proven environmental risk factors other than ionizing radiation. In the 1950s and 60s radiation was used to treat "cradle cap" and this was observed to have an association 20 years later with tumors in the brain. But now the only use of ionizing radiation is to treat certain tumors. Having an occasional X-ray is low risk. Electromagnetic radiation (e.g. cell phones) is NOT a proven risk factor.  Certain tumors that run in your family might put you at increased risk, as well.

Is a brain tumor always cancerous?

No.  There are many types that are benign. In many cases these can be cured with complete surgical removal.  Some benign tumors, however, are in "malignant" locations that might not allow for complete removal with surgery.  If all of the tumor can’t be removed, it might be necessary to treat with stereotactic radiosurgery, a form of focused radiation treatment performed by the radiation oncologist and a neurosurgeon.

My doctor told me that I have a brain tumor. What should I do next?

Some tumors require urgent surgery.  Others can be scheduled when it’s convenient for you.  Based on the imaging report, your primary care physician can tell you if it is likely a benign tumor, a slow-growing lesion or a more serious tumor.  Either way, it is important to make arrangements to see a neurosurgeon, preferably one with specific expertise in treating brain tumors.
