Brain Tumor. Rarely is a brain tumor the cause of headache. Headache can be either a late or early symptom of a brain tumor, depending on the location of the tumor. A constant, progressively increasing pain or a change in the character of headache pain may alert the physician to this occurrence.
Some of the more common triggers for headache are lifestyle related, such as poor diet, stress, muscle tension, and lack of exercise. Serious underlying disorders, such as brain tumours, are rarely the cause of headache, although persistent headache should always be investigated by a doctor. Headache can be classified into two broad categories: primary and secondary. Examples of primary headache include cluster and tension headaches.
