Multiple sclerosis is an autoimmune disease that affects the brain and spinal cord (central nervous system). Multiple sclerosis (MS) affects women more than men. The disorder is most commonly diagnosed between ages 20 to 40, but it can be seen at any age. MS is caused by damage to the myelin sheath. This sheath is the protective covering that surrounds nerve cells.
Typically benign tumors, adenomas often press on the pituitary gland, causing loss of function of one or more hormones. Many pituitary adenomas are called âfunctioning tumorsâ because they actually make hormones and may cause an increase in hormone levels instead of a decrease.
Heart Tumors. Any type of abnormal growth in the body is called a tumor, whether it is determined to be cancerous (malignant) or non cancerous (benign). Malignant tumors are fast growing and likely to spread to other parts of the body quickly, while benign tumors are slow growing and often harmless depending on where in the body they are located.
