Pituitary dependent hypercortisolism, more commonly known as Cushing's disease, is caused by a pituitary tumor (non-cancerous) that triggers excessive levels of the stress hormone cortisol.
Other tumors or conditions also may lead to excess secretion of cortisol, such as tumors of the adrenal gland and lung. This is called Cushing's syndrome. If left untreated, Cushing's syndrome (as well as Cushing's disease) can seriously affect the quality and length of life.
