Prolactinoma Resource Guide

At a Glance

A prolactinoma is a benign, non-cancerous tumor of the pituitary gland that is highly treatable. Most patients are successfully treated with medication rather than surgery. This guide provides the foundation for navigating your diagnosis, lab results, and treatment plan.

Welcome to your resource guide for understanding and managing a prolactinoma. Being diagnosed with any type of tumor can be an overwhelming and frightening experience, especially when it involves a structure in the brain like the pituitary gland.

This guide is designed to empower you with evidence-based information, cutting through the medical jargon to give you clarity on what a prolactinoma is, how it behaves, and what your treatment journey will likely look like. It is important to know right from the start that prolactinomas are benign (non-cancerous) and are highly treatable, most often with medication rather than surgery [1][2].

Here, you will learn how to navigate your diagnosis, audit your own lab results, understand your treatment options, and prepare for a healthy life beyond diagnosis. The pages in this guide are structured to answer your most pressing questions, providing practical advice to help you become an active partner in your care.

How to Use This Guide

At the top and bottom of each page, you will find targeted questions to ask your doctor and self-reflection questions to help you clarify your own needs and priorities.

Common questions in this guide

Is a prolactinoma a type of brain cancer?
No, prolactinomas are benign, which means they are non-cancerous. They are highly treatable tumors located in the pituitary gland.
How is a prolactinoma usually treated?
Prolactinomas are most often treated successfully with medication rather than surgery. Your healthcare provider will evaluate your lab results and symptoms to determine the most effective treatment path for you.
Which specialists will I need to see for a prolactinoma?
Patients with a prolactinoma typically see an endocrinologist to manage hormone levels and medication. Depending on your specific tumor and treatment plan, you may also need to consult with a neurosurgeon.
Who should I contact between appointments if I have questions?
It is important to establish a main point of contact at your clinic for any questions that arise between visits. Ask your doctor whether you should reach out to the endocrinologist, a specialized nurse, or another care team member.
