Non-functioning pituitary tumors usually do not stop growing, and there is a risk of further enlargement causing compression and other injuries, so surgical resection is recommended. Pituitary tumor is one of the common neuroendocrine tumors with relatively high incidence. Pituitary tumors are classified into functional pituitary tumors and non-functional pituitary tumors according to functional classification. Anaplastic pituitary tumors just do not have pituitary endocrine function, but their tumors also have the possibility of enlargement. Further enlargement of non-functioning pituitary tumors may lead to localized compression symptoms, such as visual field damage or visual field disorders when the optic cross is compressed, as well as symptoms such as headaches. Surgery is required for symptoms of compression, with the goal of safely removing the tumor, relieving clinical symptoms, and reducing the recurrence rate. If you experience the above symptoms or suspect that there is no functional pituitary tumor, it is recommended that you go to the hospital in a timely manner.
