Some people who have a brain tumor experience no symptoms, especially if it’s very small.

Researchers know brain tumors develop when certain genes on the chromosomes of a cell are damaged and no longer function properly, but they aren’t sure why this happens. Your DNA in your chromosomes tells cells throughout your body what to do — it tells them when to grow, when to divide or multiply and/or when to die.

When brain cell DNA changes, it gives your brain cells new instructions. Your body develops abnormal brain cells that grow and multiply faster than normal and sometimes live longer than normal. When that happens, the ever-growing crowd of abnormal cells takes over space in your brain.

In some cases, a person may be born with changes in one or more of these genes. Environmental factors, such as exposure to large amounts of radiation from X-rays or previous cancer treatment, may then lead to further damage.

In other cases, the environmental injury to the genes may be the only cause.

There are a few rare, inherited (passed down from parent to child) genetic syndromes that are associated with brain tumors, including:

Diagnosing a brain tumor can be a complicated process and may involve several specialists. In some cases, though, healthcare providers may discover a brain tumor when performing imaging tests for another medical issue.

If you’re experiencing symptoms of a brain tumor, your healthcare provider will perform a physical exam. They’ll also ask questions about your:
