Stereotactic Biopsy

A tumor in the brain is a mass of some abnormal cells. This mass can be malignant or benign. Malignant tumors are cancerous and benign tumors are non-cancerous. Primary brain tumors originate in the brain; these form in the brain tissues. Secondary brain tumors originate in other parts of the body and spread to the brain. Usually malignant tumors become secondary tumors which form when cancer spreads from other parts of the body.

Symptoms and Diagnosis:

The symptoms of brain tumor are seizures, vomiting, headaches, nausea, issues related to vision or hearing, etc. These are the usual symptoms. However there are certain symptoms that are specific to the location of the tumor: pressure near the location of the tumor, problems in performing

After that, x-rays are used to take pictures of nerve roots and spinal cord.

Skull X-ray: The doctor uses skull x-ray to learn about any calcium deposit in the brain. Many times changes in the skull bones are also checked using the X-ray.

Biopsy:

o Surgical Biopsy: This biopsy is done during the tumor removal surgery. The surgeon will take a hard-to-reach tissue sample during the surgery. o Stereotactic Biopsy: During this process, either CT or MRI is used. The images captured by these devices help the surgeon to determine the exact location of the needle in the targeted tissue from the tumor. o Needle Biopsy: Like other needle biopsies, the surgeon uses a needle to remove the suspicious tissue sample. But a small hole in the skull is first made, known as blur hole in order to pass the needle through it.

Risks Associated with Screening:

Although the tests are the only ways to detect brain tumors, sometimes these tests may pose some risks. For example, during a stereotactic biopsy there are chances of bleeding which can cause mild problems like headache to serious issues like stroke, coma and the worst,
