There is no authoritative data to show how long malignant meningioma can live if no surgery is done. According to clinical experience, the survival period of patients may be around half a year to one year, but it is also related to the degree of malignancy and is not fixed.
Malignant meningioma will cause direct compressive damage to the surrounding brain tissues and brainstem, while extracranial metastasis or multiple distant metastases may gradually appear as the disease progresses.
If malignant meningioma is left untreated, the growth and metastasis of the tumor will directly cause damage to the body and decrease the function of the immune system, and at the same time, it will cause the symptoms of gliosis in the brain tissue, which will directly affect the life expectancy.
Generally speaking, after the discovery of malignant meningioma, surgery should be carried out as early as possible to remove the tumor, and after the surgery, regular radiotherapy can effectively control the proliferation and spread of cancer cells, so as to slow down the onset of malignant tumors, and to achieve the purpose of prolonging the life expectancy and protecting the health of the organism.
Therefore, it is recommended that patients should seek medical treatment as early as possible and actively treat the tumor under the guidance of doctors, so as to avoid delaying the condition.
