Signs and symptoms of brain cancer can be either general or specific and depend on:
General symptoms of brain cancer are caused when the tumor is putting pressure on the brain or spinal cord. Specific symptoms are caused when the tumor is inhibiting the function of a specific part of the brain.
Certain symptoms, such as drowsiness, nausea, or fatigue could be related to conditions other than brain cancer. However, if you notice them in combination together or with any of the other symptoms listed, be sure to schedule an appointment with your physician.
