[|Human|] My girlfriend had a MRI last Thursday she received her MRI readings last Friday. The DR. said that she had a 3cm Lesion on the left side of her brain. She gets really bad headaches and sometime messes her speech up. How serious could this be? She is 22 5,8 125lbs. this is the first time it has been this serious.
[|AI|]  Hello and welcome to Chat Doctor ! I read your question carefully, and I understand your concern. However, I am afraid that you do not provide enough information. A lesion in the brain is a very non-specific term, could mean anything a tumor, an infection, inflammation, stroke, malformation etc., could be something really life-threatening or something completely benign which she might have had since birth. So please write again providing this time the full MRI report so that we read the full description. That along with some more details on the time course of her symptoms might allow us to provide a more informative answer. Looking forward to hearing from you again.
