10 Common Brain Diseases

8. Brain tumor

A brain tumor any mass of abnormal tissue cells, which form a growth inside the brain. These growths can be benign (non-harmful) or malignant (cancerous). Either way, they can cause problems by the pressure they cause onto the brain. Tumors grow because more and more cells combine into the mass. As it grows in size, the risk of seizure, motor function disruption and confusion grows. Doctors can treat cancerous tumors or remove them depending on location and size. Treatment is not always required in the case of benign tumors, unlike cancerous tumors, they will not spread to other parts of the body.
