4. Vomiting
The need to throw up can be a stand-alone symptom but it will most commonly present itself in a bundle of symptoms. Vomiting that accompanies dull, persistent headaches is reported widely in brain tumor patients. When you need to throw up in the morning, even when not feeling queasy, this could be tumor-related. Besides being most common in the morning, when a tumor is behind the seemingly random but persistent need to throw up, it is linked to sudden movements.
These could be as simple as rolling over in bed, standing up quickly, bending down, changing from jumping to skipping, or suddenly engaging in physical activity. The abruptness and any usual feelings of nausea prior to throwing up are what would link vomiting to a brain tumor. It is usually therefore due to something else if you feel nauseous and expect to throw up, or your vomiting can be explained by something else such as a migraine or bug.
