Does a severe headache indicate the presence of a brain tumor?
Not necessarily. Headaches do occur with brain tumors, typically when they become large and are associated with swelling, but they are still an uncommon symptom. Headaches are far more common in other diseases, including migraines and arthritis of the neck. If you are now having headaches that you never had before, you should see your doctor. However, the probability is still relatively low that the onset of headaches is caused by a brain tumor.
