What are the symptoms of pituitary tumor recurrence?

The most common symptom of pituitary tumor recurrence is headache, which often occurs persistently. Following recurrence, patients may experience vision deterioration, primarily characterized by blurred vision in one or both eyes. As the condition progressively worsens, patients may eventually become blind, which is one of the most common symptoms after tumor recurrence. In women, pituitary tumor recurrence can lead to menstrual irregularities or amenorrhea, and sometimes spontaneous milk discharge from the nipples may occur.
