Pituitary adenomas, also known as pituitary tumors, are treated mainly with surgery and, depending on the circumstances, with adjuvant radiation therapy or medication, for example, in the early stages of lactogenic pituitary tumors, they can be treated with the oral drug bromocriptine. If the prolactin continues to be greater than 500 ng/mL during the course of the medication and the tumor continues to grow, surgery should be considered. If other types of pituitary tumors cause clinical symptoms, surgery needs to be considered. For recurrent or invasive tumors, radiation therapy may be considered when surgical removal is difficult. Therefore, in the treatment of pituitary tumors, it is necessary to consider the size, nature, and growth direction of the tumor in relation to the surrounding tissue structures, and to emphasize individualized and comprehensive treatment.
