Under normal circumstances, pituitary tumors generally do not heal spontaneously. Pituitary tumors are benign tumors and although they grow slowly, they tend to continue growing. When they enlarge to a certain extent, they produce a series of symptoms and signs, such as headaches behind the eye sockets, the forehead, and both temporal sides. If the tumor breaks through the sellar diaphragm, it might also affect the optic nerve, leading to decreased vision and visual field defects. Moreover, it can severely erode the pituitary gland, causing symptoms and signs like decreased pituitary function, endocrine hormone disorders, and bringing significant suffering to the patient.
