I Have A Meningioma In The Left Frontal Lobe, I

I have a meningioma in the left frontal lobe, I have had seizures. tia's, and frequent falls. But the recent problem is that my vision is decreasing in my left eye. My eye specialist is concerned that if I do not have this addressed, then I will lose vision in my left eye. She feels that it needs to be removed.
this may make my migraines better also?
What is the answer?
