In 1994 my wife had the same symptoms. They operated on her in Springfield but found that they could not get to all of the tumor. However, they cut the eye nerve that controls her right eye as far as looking down. Found that tumor was benign but had to be removed. After a short recovery time, we went to KC to the new (then) Gamma Knife hospital. They worked on her all day shooting controlled radiation. One area could not be hit but they hoped the treatment might bleed over to stop the growth.
That was 24 years ago and each year she get a new MRI. No new growth yet and she is still as mean as she ever was.
KEEP YOUR STRONG FAITH IN THE LORD.
