Most likely: It is good to note that your periods have resumed. Please have your prolactin levels rechecked. Your endocrinologist will probably recommend a follow up MRI to see if the tumor has shrunk.

Maybe: This is a great sign & shows the Cabergoline is doing something & this may all be a prolactinoma. That said, this size tumor will often (not always) produce much higher prolactin levels & the elevated prolactin may be do to something called pituitary stalk compression, now lessened as Cabergoline will shrink most pit tumors. If the case a surgery would be safer/easier. Good news either way!
