My name is orville,when they found mine it was 11mm.7 will block you're fluid and kill you.if you're really young they might remove it,but there are only about 125 cases in the us.they're less than 1percent of brain tumors.most doctors are not qualified to even think about doing it.they pull your face off and remove the top half of your skull.they will keep telling you they are going to keep an eye on it.you will get tinnitus,double vision,your walk will change,a lot of bs.i recommend you stay out of dark quiet places,because that tumor will get into your head really bad.myself I leave my bathroom light on.best of luck.i am also at risk of sudden death,after 7 mm,you're almost there.so sorry
