I am 20 years old and was told i have a beligna brain tumor on the left side of my head. The reason for finding this was due to headachs and being sick. I quit smoking about 3 weeks before i found out and now ive been sick with multiply symptoms rranging from asthma, uti, stomach virus, cold , sinus infection, ear infection, migrains, weird vision ect... i was wondering if this could be from quiting smoking or were these the symptoms of the tumor. My doctor has not sent me to a neurologist or any other specialist, if it was serious enough to see a doctor would he automatical send me to one, i had a mri done, thats how it was found..would a mri tell if it was serious. Will a tumor ever disappear?
