Does persistent head aches related to tumor in brain?

Depends: Does this person already have a tumor DIAGNOSED and present in the brain? Or are you worried about the possibility of having a brain tumor based upon having persistent headaches? If the former then, this is not uncommon...if the latter then, a simple physical examination will disclose the likelihood that the headaches are pointing to something more complex inside the head (usually not though).

Usually not: There are many causes for headaches. Headaches are not usually from brain tumors, but if you are having persistent headaches see your doctor or a neurologist. Make sure you are drinking plenty of water as dehydration can cause or worsen headaches.
