Would children tylenol (acetaminophen) get rid of brain tumor headache in toddler? if a tumor was present would more symptoms be present beside headache?

Please clarify: Looking at the bigger picture it appears you are concerned that a child may have a brain tumor. However, it would appear also from the question that there has not been a diagnosis made to this point of such a thing. The child simply has a headache. Is that correct? I see no downside to using pediatric tylenol (acetaminophen) preparations in this particular case. What else is going on to worry you for a tumor?
