It depends on the location of the tumor. Most commonly, a brain tumor will increase the pressure within the skull as it grows, forcing the medulla (the lowest part of the brain) downward into the spinal canal. Compression of the medulla can seriously affect blood pressure, breathing, and heart rate.

This type of tumor typically forms within the bones of the skull or vertebrae, rather than in the brain itself. Treatment usually involves surgery to remove the tumor.
The Abdominopelvic cavity is used. But these are two different cavities put together (abdominal cavity and the pelvic cavity). These two cavities hold completely different organs of our body they have different purposes. To be better understood and to be able to correctly diagnosed they should not be referred to as one cavity.
