In some ppl with micro-prolactinomas, a 6 month course of bromocriptine can cause long term suppression of prolactin secretion. If that doesn't work, or if you're not a candidate for bromo therapy, then there is a procedure called a transphenoidal resection of the tumor. Here is a link that describes the procedure:

They basically go through your nostrils with a long needle and thin camera (endoscope). It's done by brain surgeons (neurosurgeons) so I have no experience with this.

Regarding bromocriptine therapy, I'm not sure if that's still the first medical option or if there has been a transition to the use of cabergoline (or possibly pramipexole but I highly doubt it as is not FDA approved for the treatment of prolactinomas).

But see a doctor and get evaluated before you start worrying about all this stuff.
