Is any of this happening?
Be seen today
If you already have a pituitary tumor, contact your care team promptly for worsening headaches, new visual symptoms, major changes in thirst or urination, or a return of previous hormone-related symptoms.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you develop persistent headaches with gradual vision changes, unexplained menstrual or sexual changes, milky breast discharge, unusual growth-related changes, or symptoms suggesting a hormone imbalance.
These symptoms often have other explanations, but they deserve assessment.
Keep planned follow-up appointments even when you feel well.
Every sign above is quoted from the sofidex article on Pituitary tumor. If you are not sure, err upward — it is always reasonable to be checked.
