Cavernous angioma

I had a grand mal seizure in my sleep in October.I became very violent and couldn't remember anything.The doctors dianosed me with a cavernous angioma in the right temporal lobe.They also found a venious angioma on my left lobe plus stenosis of artery in the left neck and a thyroid cyst.now,i've seen 4 neurosurgen's 3 want to remove the cavernous angioma on thr=e right lobe but one is conservative.I'm confused what to do.They say as i get older the angioma might leak and cause a stroke.So should I have it removed or could it be caused from other conditions. Thanks
