What do you suggest if my mother aged 50, was being treated for migraine for the past 5 years untill a ct scan revealed she had a tum?

Secondary headache: Primary headaches do not have an organic (tumor) cause. When evaluating a patient's headache, it is imperative that the physician first identify and exclude a secondary headache based on history and clinical examination before proceeding to the diagnosis of the primary headache (migraine) disorder. Even a patient with a previously diagnosed primary headache can have a secondary headache.
