However , in rare instances , the disease can be triggered by tumors elsewhere in the mastermind orin other parts of the body , such as thelungsorpancreas . These tumors either produce growth internal secretion themselves or make another substance , cognize as growth - hormone - give up internal secretion , which , in turn , prompts the pituitary secretory organ to make more growth hormone .

Acromegalyis curable in some case . In patients who have a pocket-size pituitary secretor tumor that can be removed via surgery , the disease can be cured 85 % of the clock time . For affected role with bombastic - but - obliterable tumors , it can be bring around between 40 % and 50 % of the fourth dimension . Unlike surgery , drugs ca n’t cure the circumstance , but they can help control patients ' symptom .
