good morning. my names james i have been diagnosed with a 53mm cerebral cyst wich they think is arachnoid 2 yrs ago. i didnt do any follow up when i found out because i was in perfect health besides the fall that required the ct scan . about 6 months ago i had a massive headache wich i couldnt move talk or do anything becuase the pain would increase. i vomited and passed out for 30 hours. then about 2 months ago i randomly collapsed and again vomited and passed out. so i went to the doctors after that an got a mri. they confirmed my cyst grew to 7cm and they also found a venous angioma and hemosiderin from early cavernoma. i just want to know how worried i should be and if i should tell my family. also a little medical backround about family history- 2 of my sisters had surgery to remove cancer cells in there ovaries, my farther and my brother are epileptic my brother was for 10 yrs and stopped taking meds and has been perfect since(10+yrs). can someone give me and idear of what i could be dealing with or some ideas of things i should do.
