Unlikely. Headaches are common and are often caused by stress or tension. It could also be migraine which is also quite common. Brain tumors do cause headaches but are relatively rare. You should have your doctor examine you and test you for the likely cause and treat it appropriately. A specialist/ neurologist may be consulted if your pcp is unable to control it well and to your satisfaction.
