A biopsy is a procedure wherein a small sample of the suspected tissue is harvested from the body. Afterward, it is examined under a microscope to determine whether it’s cancerous or not.
Biopsies can be done as a part of surgery to remove a brain tumor, or a standalone procedure. If it’s the latter, then a tool called a stereotactic needle is typically used to retrieve a sample. Though, this is rarely done with brain tumors nowadays. If the tumor in the brain is metastatic and the primary tumor is more accessible, the primary tumor is subjected to a biopsy procedure instead.
A lumbar puncture is a procedure wherein a sample of your cerebrospinal fluid is taken by inserting a needle into the spine. During this procedure, local anesthesia is typically used. The sample will then be studied to check for signs of a tumor or cancer.
Can Brain Tumors be Cured?
Answering the question of whether or not brain tumors can be cured usually depends on the type of tumor. If the tumor is benign, which means it’s not cancerous, it usually can be treated without any serious complications.
But if the tumor is malignant or cancerous, treatment can be more difficult.
Treatment Options for a Brain Tumor
Depending on the prognosis made by the doctor, the following options can be provided.
For both malignant and benign brain tumors, surgery is a viable form of treatment. This involves removing a part of the skull to access the brain directly, and cutting out the tumor.
