Can Prolactinomas Grow Back?

Prolactinomas can come back within five years. We will monitor you, especially if you had a large prolactinoma. Our research shows that these tumors can be especially aggressive in men. We have also developed ways to predict how likely a tumor is to return, based on a study of more than 800 of our surgical patients.

Do prolactinomas go away?

A prolactinoma won't go away on its own without treatment. Long-term medication can shrink the tumor until it's gone. However, it's important to note that prolactinomas can come back, even after successful treatment with medication or surgery.

Can prolactin come back?

The higher the prolactin level, the slimmer the chance that prolactin production will return to normal after surgery. Surgery corrects the prolactin level in most people with small pituitary tumors. However, many pituitary tumors come back within five years of surgery.
