<human>: doctors discovered that 20 years old friend of mine had brain tumor and surgery was conducted to solve the case,2 years after surgery he started drinking alcohol a lot i guess he is an addict ,when we have just a normal chat it takes almost a minute to respond to me.i remember one day he fainted. what does those signs show?,do you mean the problem still exits? please elaborate what could be the problem. thanks in advance.
<bot>: Hi, Thank you for posting your query. There are several reasons that could cause problems in your friend:1. Recurrence of the tumor-some tumors can grow again after surgery, this can be found out with a repeat brain scan.2. Seizures-brain tumor and surgery can leave a scar in the brain, which could cause seizures and result in fainting.3. Alcohol relatedPlease show to a neurologist for opinion. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly/
