Detection Of Brain Cancere

The presence of the above symptoms may lead a physician to suspect brain cancer. A CT scan or magnetic resonance imaging (MRI) are the first examinations to be performed to properly diagnose a brain cancer, whatever the type. These specialized radiological examinations can detect many types of brain tumors and determine their location and size accurately. However, they do not determine whether the tumor is cancerous or not.

We must perform a biopsy to determine if the tumor is cancerous. For this, we take a sample of the tumor during surgery. If the tumor is too deep in the brain, surgeons can use a technique called stereotactic biopsy or establishment of the needle through three-dimensional approach. This technique uses an MRI to create a three dimensional image of the brain that are then used to guide a needle contained in a special case to the appropriate region of the brain. It sucks and is collected tumor cells in the needle for analysis. Once collected, we analyze the biopsy sample using microscopes and special chemicals to determine the type of tumor. It usually takes several days before obtaining the results of a biopsy.

We may sometimes collect cells of brain tumors in cerebrospinal fluid (CSF), a special fluid that surrounds the brain and spinal cord. CSF samples are taken using a thin needle that is inserted in the lower back under local anesthesia, this procedure is called a lumbar puncture. We can do this procedure when too much pressure accumulates in the brain. Indeed, the pressure change resulting from the brain drain may cause aspiration of part of the brain tissue at the base of the skull, causing serious complications.
