In fact, cavernous hemangioma is not a true tumor, but a vascular malformation lacking an arterial component and is a benign disease. Whether it is life-threatening or not depends on the site of onset. Generally speaking, if the site of onset is in a non-fatal, resectable area, the patient is treated as if it were a benign disease and does not affect the person’s natural survival time. Therefore, when cavernous hemangioma is found, it is generally not necessary to be overly nervous, and it is sufficient to go to a regular hospital to receive active treatment in a timely manner. However, it is important to note that if the onset of the disease is in a specific area such as the brain stem, it may be a serious health hazard. In conclusion, cavernous hemangioma generally does not have a significant impact on the life expectancy of patients, but since patients with cavernous hemangioma are likely to have seizures, measures should be taken to prevent falls and trauma, and review should be done in strict compliance with medical advice.
