If you are experiencing severe or regular headaches, it might be the symptom of something far more serious. A headache is a common early sign of a brain tumor.
You should be especially concerned if you are regularly waking up with headaches. Equally, if your headaches are more intense than usual or continue throughout the day, it is a good idea to consult your doctor as soon as possible.
A tumor causes headaches by increasing the pressure on the brain. Called Increased Intracranial Pressure (IICP), this can be in the form of excess fluid or mass or even brain swelling itself.
The skull only has enough room to house the brain and a regular amount of fluid. Any excess tissue or fluid will increase the pressure and cause pain.
