The most common form of treatment for brain tumours is surgery. An aperture is made in the skull by a neurosurgeon to remove a brain tumour. The procedure is known as a craniotomy. The surgeon makes every effort to get rid of the whole tumour. Your doctor may remove as much of the tumour as feasible if it cannot be entirely eliminated without harming important brain tissue. By relieving pressure on the brain, partial removal aids in symptom relief and minimises the quantity of tumour that requires radiation therapy or chemotherapy. Unremovable tumours include some. Your doctor might only perform a biopsy in such circumstances. A pathologist will take a small portion of the tumour and analyse it under a microscope to identify the sort of cells it contains. This aids your doctor in selecting the best course of action. A needle is occasionally used to do a biopsy. To determine the precise position of the tumour, doctors employ a specialised head frame (similar to a halo) and CT or MRI scans. A small hole is made in the skull by the surgeon, who then inserts a needle to reach the tumour. Stereotaxis is the practise of performing a biopsy or receiving therapy using this method.
