In brief: Not usually
Although extremely uncommon, glioblastoma has been found outside of the nervous system in a metastatic fashion, most often inthe lungs or lymph nodes.
It is usually found after surgery for the brain disease.

In brief: No
A tumor/cancer that is originated from brain as primary organ ( primary brain tumor/cancer) does not spread outside the brain.
Now, however, many cancers that are originated from other parts /organs in the body ( such as breast cancer, lung cancers, etc) can spread to the brain ( metastatic cancer to brain). Metastatic cancer to brain is far more common than primary brain cancer/tumor.

In brief: No
Brain cancers do not spread outside the head, unless a shunt has been placed connecting the inside of the brain with, usually the peritoneal cavity.

In brief: Very rarely
This depends on the type of brain tumor.
In general, primary brain tumors do not spread to the rest of the body (metastasis). There are rare cases in which primary brain tumors can spread to other organs.
