<bot>: Hi, welcome to Chat Doctor. I understand your query as well the concern. Your history looks like that the lump might be attached with the brain, because of that you are having speech, vision & balance problem. But it needs to be confirmed by USG of the lump to rule out whether it is attached to the brain or just superficial. Then consult any doctor/surgeon nearby for further guidance. Good luck, Thanks.
