Brain Tumors Cancer Treatment

Brain Tumor Overview

Despite popular belief, there is no one form of brain tumor, and not all brain tumors are cancerous. Cancerous tumors are malignant in nature. They grow rapidly and aggressively, and can also spread to other parts of the body. On the other hand, tumors that do not invade other healthy tissues of the body are called benign tumors. Benign tumors do not present the same risks as malignant tumors, but they can still impair the brain's normal functioning.

In itself, our brain houses different kinds of cells, making up different tissues. In terms of primary brain cancers, one type of cell deviates from its normal functioning and transforms itself to reproduce rapidly. This rapid growth leads to formation of a tumor.

Such tumors, which originate in the brain are called primary brain tumors. Whereas, metastatic brain tumors are caused due to a process called metastasis, in which cancer cells travel to the brain through blood vessels or lymph vessels from other parts of the body that are infected with cancer.
