Cancer is one of the most dreaded degenerative diseases with a wide range of types and sites. Virtually every organ and tissue in the human body is vulnerable to cancer. For reasons not yet understood, certain cells in a body tissue may break away from the orderly and controlled pattern of normal growth and begin reduplicating at a greater rate of speed. This accelerated growth becomes an enlargement, or a tumor. These new growths, or neoplasms, may remain clustered in the localized area of the tissue where their growth took place. They do not have a tendency to spread or metastasize by invading surrounding tissues or by seeding more distant tissues. These types of neoplasms are called benign tumors. In most cases, benign tumors can be surgically excised and permanently removed. There is, however, one type of benign tumor that is extremely dangerous. This is a meningioma. A meningioma grows from the cells of the meningeal tissues stretched over the brain. As the tumor grows larger, it takes up space within a confined area. The pressure exerted by its increasing size can often destroy delicate brain tissue.
