The most obvious sign of female pituitary tumor is endocrine disruption caused by hyperprolactinic adenoma, in addition to headache and visual impairment. The pathologic type of female pituitary tumor with the highest incidence rate is prolactin cell adenoma, therefore, in addition to headache and visual impairment caused by pituitary tumor compression, the earliest sign is the excessive secretion of prolactin by the tumor cells, resulting in hyperprolactinemia, which is most common in young women and manifests as amenorrhea, breast milk overflow, and infertility. It should be noted that the endocrine symptoms of postmenopausal women are not significant and are not easy to appear in the early stage, and only when the tumor grows to the saddle and causes damage to the visual field, it will be diagnosed, and then the tumor body is more huge. It is suggested that patients should go to regular hospitals for treatment according to their own symptoms in time, so as to avoid delaying the condition and causing serious consequences.
