- Malignant Brain Tumor
Malignant brain tumors do not have distinct borders and tend to grow rapidly, causing pressure within the brain. It is highly unlikely for malignant brain tumors to spread beyond the central nervous system.
* Malignant tumors are more serious and often life-threatening
* Cells can break from the malignant brain tumor, spreading to other parts of the brain or to the spinal cord. Rarely do these cancerous cells spread to other parts of the body
