Astrocytoma is a type of brain tumor that originates in the star-shaped brain cells known as astrocytes. Common synonyms for astrocytoma include glial tumors, gliomas, and astroglial tumors. These tumors are typically graded based on their level of malignancy, with grades I and II being considered low-grade and grades III and IV being high-grade. Other synonyms for astrocytoma may include diffuse astrocytoma, anaplastic astrocytoma, and glioblastoma multiforme. Treatment options for these tumors may include surgery, chemotherapy, and radiation therapy, depending on several factors such as the tumor's location and grade. It is important to consult with a healthcare professional if any symptoms are noticed that may suggest the presence of a brain tumor.
