What is a brain biopsy?

A brain biopsy is a diagnostic procedure in which a small piece of tissue is removed from the brain for examination under a microscope. This procedure is typically performed when a doctor suspects a patient may have a brain tumor, infection, or other abnormality.

During a brain biopsy, a surgeon makes a small incision in the scalp and drills a hole in the skull. A needle or other surgical instrument is then inserted through the hole to remove a sample of brain tissue. The sample is then sent to a laboratory for analysis.

Brain biopsies are usually performed on an outpatient basis, meaning the patient can go home the same day as the procedure. However, in some cases, a patient may need to stay in the hospital for observation overnight.

Brain biopsies are generally considered safe, but there are some risks associated with the procedure, including:

* Infection

* Bleeding

* Swelling

* Damage to the brain tissue

* Seizures

* Death

The risks of a brain biopsy are typically outweighed by the potential benefits of the procedure. Brain biopsies can help doctors to diagnose brain conditions and develop treatment plans.
