A meningioma of 8 mm is not yet a particularly serious matter, but it must be given clinical attention. This is because meningioma, as a form of intracranial tumor, is distinguished by its benign and malignant nature. If it is benign, only the occupational effect affects the skull. In the case of malignant cases, there is more than just an occupational effect. Therefore, in these aspects, it is important to review the meningioma as regularly as possible to clarify the specific rate of growth and the specific nature of the meningioma in order to have very good treatment and treatment indications. With the advancement of technology, for meningiomas as small as 8 mm, it is possible to first try to apply radiotherapy, which is also commonly known as baking electricity. However, the efficacy of the treatment must be reviewed periodically to be able to evaluate it specifically. If the tumor does increase rapidly in a short period of time, craniotomy must be performed in a timely manner, as it may be a malignant condition and very dangerous.
