Surgery is often the primary treatment for many types of brain tumors, aiming to remove or biopsy the abnormal tissue and alleviate symptoms. Here's what you need to know about surgery for brain tumors:

1. Craniotomy Procedure: During a craniotomy, a neurosurgeon creates an opening in the skull to access the brain tumor. This allows for direct visualization and precise surgical intervention. The extent of tumor removal depends on factors such as tumor size, location, and proximity to vital brain structures.

2. Tumor Removal: Whenever feasible, surgeons aim to completely remove the brain tumor to achieve the best possible outcome. However, in some cases, only a portion of the tumor can be safely excised to avoid damage to critical brain tissue.

3. Biopsy: In cases where complete tumor removal is not possible, a biopsy may be performed to obtain a sample of the abnormal tissue for further analysis. This helps guide treatment decisions and determine the tumor's characteristics, such as its type and grade.

4. Stereotactic Biopsy: Stereotactic techniques, such as CT-guided or MRI-guided biopsy, enable precise targeting of the tumor while minimizing surgical invasiveness. These minimally invasive procedures require only a small hole in the skull and offer accurate localization of the tumor.

Surgery for brain tumors is a complex procedure that requires expertise and precision. By understanding the surgical process and its goals, patients and their families can make informed decisions and actively participate in their treatment journey.
