What are the chances of a meningioma coming back?
Complete removal of a meningioma and dura is the best way to avoid a recurrence. However, there is still a 24 to 32 percent chance that a meningioma will recur in 15 years, even when the original tumor was completely removed. In about 95 percent of recurrences, the new meningioma grows in the same spot as before.
