Doctors, what are the different symptoms for migraine headaches and brain tumors?

Secondary headache: A secondary headache is an organic headache that is symptomatic of an underlying problem. These conditions include some of the more ominous conditions (e.g., brain tumors, brain hemorrhage) as well as some benign conditions such as sinus infections and allergies. When evaluating a patient's headache or migraine it is imperative to exclude a secondary headache.
